A zero clearance insert is a replacement throat plate with a kerf slot cut to match your saw blade width exactly, so the workpiece is fully supported on both sides of the blade and nothing can drop into the saw cabinet. That single change is the difference between a clean bottom face on plywood and a splintered mess, and it is the fastest upgrade you can make to almost any table saw. If you are still shopping for a saw, start with our table saw buying guide first, then come back here to fit it out properly.
The catch is that inserts are model-locked. A plate machined for a Ridgid TS3650 will not drop into a DeWalt DW744 opening, and generic listings that say fits most table saws are usually describing a rectangle rather than a fit. We went through eight of the most widely reviewed inserts on the market and matched each one to the saw it was actually built for.
Below you will find a model lookup list, the mechanics of how the slot gets cut, a material breakdown, and eight reviews covering phenolic, UHMW and MDF plates, OEM and aftermarket designs, and the awkward job site saws that nobody else seems to cover. Every rating and review count here comes straight from the listing, and where owners report a real problem we name it. Several of these plates have a genuine Achilles heel, and you should know about it before you buy.
What Is a Zero Clearance Insert?
A zero clearance insert, often shortened to ZCI in forum threads, is the flat plate that sits in the opening of your table saw top. It is also called a zero clearance throat plate, and you will see it misnamed as a zero tolerance insert by people searching for one. All three names refer to the same part.
The plate that comes with a saw is either thin pressed steel or plastic, and its opening is always cut wider than the blade. That gap is deliberate on cheap plates, because manufacturing to a blade-exact slot would be expensive and would not accept every blade change. The gap has consequences: the workpiece loses support right at the moment of the cut, and the unsupported fibres are torn downward, which is the tear-out you see on the bottom face.
A zero clearance insert fixes the support problem. The slot in an insert is cut with the very blade that will run in it, so the kerf is a few thousandths wider than the blade and nothing more. Wood fibres on both sides of the cut are held right up to the blade, which removes most of the chip-out. A second benefit matters just as much: nothing small enough to fall through that slot can reach the blade or the cabinet below.
Dado inserts work the same way but with a wider slot sized for a stack of blades rather than a single one. If you run dados for joinery, you need a second plate cut for that stack, because a single-blade slot will not safely clear a dado set.
Key Benefits
Stops small parts dropping into the saw. Thin offcuts, strips and slivers cannot fall past the blade into the cabinet, where they can sit against the arbor assembly and ruin a cut or a blade.
Eliminates tear-out on the bottom face. Supporting the fibres at the cut line is the whole point, and it is where most of the improvement shows.
Prevents the workpiece falling into the blade. Without a support gap, a cut-off piece stays on the table instead of tipping into the rotating blade.
Makes flush and repeat cuts practical. A narrow strip needs a continuous surface to ride on, and a zero clearance plate provides one.
Reduces dust and noise. With no open slot, far less sawdust is thrown upward out of the opening, which also helps shop dust collection.
One honest limitation up front. A zero clearance insert does nothing for a bevel cut. Tilting the blade opens a wedge-shaped gap that is as wide as the tilt angle, so the benefit disappears the moment the blade leaves vertical.

1. Bosch TS1005 Zero Clearance Insert for 4100 and 4000 Saws
Bosch TS1005 Zero Clearance Insert Assembly for Table Saws Red 4100, 4000
OEM drop-in for Bosch 4100 and 4000
Also fits the 4100XC
13.75 by 3.75 by 0.5 inches
Pros
- Reduces tear-out on cut edges noticeably
- Quick drop-in installation with no complicated fitting
- Works across the Bosch 4100 series including the 4100XC
- Largest body of owner feedback of any insert here
Cons
- Thin stamped construction can flex under a heavy rip
- Plastic surface shows wear and collects dust over time
This is the one to buy if you own a Bosch 4100, 4000 or 4100XC and want the shortest possible path to a clean cut. It is the OEM part, made by the saw manufacturer, which means the geometry matches the opening without any sanding or adaptation. With 832 ratings behind it, this is the most thoroughly owner-tested insert in the category by a wide margin.
What you give up for that convenience is rigidity. Owners repeatedly note that the thin plate is less stiff than a phenolic or MDF aftermarket insert, and a few mention flex under heavy ripping. The plastic surface is also the first thing to wear, and it tends to pick up dust that has to be cleaned out of the opening.
The practical read on this plate is that it solves the two things most people care about. The kerf closes to blade thickness, so tear-out on plywood drops off, and the gap that used to swallow small offcuts is gone. On a benchtop saw that spends its life cutting four-foot sheet goods, that is a complete fix.
For a contractor saw that gets loaded hard with thick hardwood, a thicker aftermarket plate will feel better. The Bosch part is a great first upgrade and a poor long-term heavy-duty solution.
How it performs on thin stock
This is where the TS1005 earns its reputation. Thin strips and narrow tenon stock sit on a continuous surface right up to the cut line, and a sliver cannot drop through into the cabinet. Owners cutting dowels and small parts report a visible confidence difference over the factory plate.
What to check before you install it
Confirm your model number is 4100, 4000 or 4100XC, since the insert itself is not interchangeable with other Bosch benchtop saws. Take a few minutes to set the plate dead flush with the table using the height adjustment before the first cut, because an insert sitting a hair proud will still catch a thin strip.
2. Peachtree High-Density Phenolic Zero Clearance Insert
Peachtree Woodworking Supply Phenolic Zero Clearance Insert compatible
High-density phenolic
Snug Fit side tabs and screws
13.74 by 3.75 by 0.5 inches
Pros
- Dense phenolic body resists wear in daily workshop use
- Snug Fit tabs make dialing in an exact fit straightforward
- Closes the gap that catches small cut-off pieces
- Substantially reduces tear-out in plywood and solid wood
Cons
- Compatibility is saw-specific so measure the opening before ordering
- A separate insert is recommended for dado blade setups
Phenolic is the material serious woodworking shops gravitate toward, and this plate carries 602 ratings from owners, a large share of them describing the same close, stable fit. The high-density body resists the daily abuse that softens an MDF insert, and at 1.2 pounds it is heavy enough to stay put without being a pain to handle.
The Snug Fit system is the part owners single out. Sandable side tabs let you trim the plate to your exact opening, and separate top and side screws lock it down with no side-to-side movement once it is dialled in. Buyers report the close, adjustable fit as the feature that made the install painless.
The most common caution is not about the plate at all. It is about the listing: the insert only fits the saw dimensions stated, so measure your factory insert and compare before ordering. That advice is repeated often enough that it is worth treating as mandatory rather than optional.
A second point worth planning around: if you run dados, order a separate plate for the dado stack. Trying to run a wide stack through a single-blade slot is how people damage both the blades and the plate.
Why phenolic holds up better than MDF
Phenolic does not soften, chip at the edges or absorb moisture the way an MDF plate does, and it will not take a pitch build-up on the blade the way melamine-coated surfaces can. The trade-off is that phenolic is brittle. Overtighten the leveling screws and it can crack, so snug is the target, not maximum torque.
Where the fit work actually goes
Expect a few light passes with abrasive paper on the side tabs, then a snug seat with no wobble. Owners who treat the tabs as a fitting system rather than a nuisance report a plate that stays put through heavy use. If your plate rocks or shifts under hand pressure, it needs another pass before it goes in permanently.
3. ZEROSERT Delta Three-Pack MDF Inserts with Dado Plate
ZEROSERT Zero Clearance Table Saw Inserts w/DADO – Delta Compatible – 36-725, 36-725T2, 36-5152, 36-5000, 36-5000T2 Table Saws (3-Pack)
Commercial grade MDF
Three plates machined identically
Dado plate and riving knife cutout
Pros
- All three plates machined identically so height transfers between blade setups
- Through-holes allow leveling without removing the plate
- Noticeably stiffer than the factory steel plate
- Clean dado grooves in plywood with no tear-out
Cons
- MDF edges sand away easily so fitting needs a light hand
- Dropping it on an edge can damage the plate
If you own a Delta 36-725, 36-725T2, 36-5152, 36-5000 or 36-5000T2 and you cut dados, this is the set to look at first. Three plates machined identically means you can run a single blade, swap to a wider blade, or drop in a dado stack, and the height stays the same without re-leveling each time.
The through-holes are the feature experienced woodworkers mention most. Because the leveling screws are reachable from the top surface, you can dial the plate to the table without pulling it back out, which saves a lot of trial and error on a first install. Users compare these favourably to self-made plywood plates on machining precision.
The dado plate and riving knife cutout are what make this a three-pack rather than three identical singles. A wider slot machined for a dado stack is the only safe way to run joints, and a dedicated plate means you are not trying to make a single-blade slot accommodate a 3/4 inch stack.
Now the honest part. MDF is a wood composite, so the edges sand away easily and a plate dropped on its corner can chip. Fitment takes a few light passes with sandpaper to reach a snug, flat seat, and a minority of buyers report a unit arriving slightly warped. Inspect the plate on arrival rather than assuming it is flat.
Best for a Delta owner who changes blade setups
If your Delta runs a dado for face frames and a thin kerf blade for sheet goods, the matched set is worth more than any single plate. The trade-off is MDF durability: treat the edges carefully during fitting, and keep spares in mind if you do a lot of dado work.
Watch the dust collection
With a full zero clearance there is nowhere for sawdust to escape upward, which improves the cut but can put more load on your dust system. Owners note cleaner work surfaces and noticeably less dust in the air, so a modest drop in extraction is a fair trade for most shops.
4. Leecraft DW-2 Insert for DeWalt DW744 and DW746
Leecraft DW-2 Zero-Clearance Table Saw Insert for DeWalt Model DW744 and DW746
Phenolic laminate with melamine surface
Precut blade pocket
Leveling and lateral screws
Pros
- Heavy phenolic body gives a solid flat insert that stays put
- Leveling and side adjustment screws match the insert to the table easily
- Reduces chip-out and splintering on plywood noticeably
- Low friction melamine surface gives a consistent feed
Cons
- Only fits the DeWalt DW744 and DW746 platform
- May need light sanding to achieve a fully flush fit
Leecraft plates come up constantly in woodworking forum threads, and the recurring theme is that they feel more substantial than anything home-made. The DW-2 is built for the 10 inch DeWalt contractor platform, specifically the DW744 and DW746, and it is one of the few inserts here with a rear anti-lift pin to stop the back edge popping up under pressure.
The precut blade bottom pocket solves a real problem on contractor saws. The blade retracts only a small distance below the table, so without a relief pocket the blade bottom can catch on the plate and stop it sitting flush. Owners report the DW-2 sitting flat and staying adjusted once it is in.
The melamine surface is worth understanding before you commit. It is slick, which genuinely helps the workpiece feed consistently, but it does pick up pitch from the blade, so you need to clean the blade a little more often than you would with a bare surface. That is routine maintenance, not a defect.
Users report the precision and build quality as a precise, well-made plate that eliminates tear-out and dust, and the adjustment hardware is what makes alignment straightforward. A light sanding pass on the sides may be needed before it is fully flush, and older saws in particular are the ones that need it.
Where a contractor saw needs rigidity most
A 10 inch contractor saw is often cutting thick hardwood at full depth, which is the load case that exposes a thin plate. The phenolic body here is stiff enough that the trade-off is fitment rather than flex, and the rear anti-lift pin keeps the back edge down when you are pushing a heavy cut.
What the DW-2 will not do for you
It is cut for one saw platform. If your DeWalt is a 7480, 7491 or 7491RS, this plate is the wrong part, and if it is a 7485 or DCS7485 you need to look elsewhere entirely. Check the model plate on your saw before you order anything from this brand.
5. CNC Custom Designs Four-Pack for DeWalt 744 Through 7491
Cncdesigns Zero Clearance Inserts (4-Pack) for DeWalt 744, 745, 746, 7480, 7491 & 7491RS, 7490 Table Saws
Four inserts plus leveling screws
0.25 inch MDF construction
Single blade slot
Pros
- Rated 4.7 stars with a strong share of five-star reviews
- Four plates cover multiple blade and dado configurations
- Snug well-machined fit that stays in place during use
- Four leveling screws let you set the plate flush with the table
Cons
- Not usable with a riving knife unless you cut your own relief slots
- Pointed leveling screws can mark the workpiece or sit proud
Four plates plus screws in one package is the reason this set carries a 4.7 star rating. If your DeWalt is a 744, 745, 746, 7480, 7491, 7491RS or 7490, you can cover your single-blade setups, your riving knife configuration and a dado stack without buying three separate plates.
Owners consistently praise the precise fit, the straightforward installation and the value of getting four plates with the leveling hardware included. The 0.25 inch MDF plate is thick enough to be stiff on a contractor saw and machines cleanly, and the four leveling screws let you bring it flush with the table.
There is one important exclusion, and it is printed on the listing. This set is not for the DeWalt 7485 or DCS7485, and it is not intended to be used with the riving knife in place unless you cut the relief slots yourself. If your saw has a permanently mounted riving knife, this is a modification job before it is an install job.
What to watch during the first fit
Pointed leveling screws are the recurring complaint. A few buyers report screws that mark the workpiece or sit proud of the table surface, so check the tops after the first adjustment and grind them flat if you are cutting finished surfaces. A small number of owners also report an insert that sits above the table, which usually means the leveling needs another pass rather than a faulty plate.
How four plates earn their place
The value is in the duplication. A single-blade plate, a plate for a wider kerf blade and a dado plate means you are not swapping to a home-made insert every time you change setup. The trade-off is MDF, which is softer than phenolic and can break if the plate is dropped or levered against something hard.
6. Leecraft RG-1 Insert for Ridgid TS3650
Leecraft RG-1 Zero Clearance Table Saw Insert for Ridgid TS3650 Table Saw
Phenolic laminate with melamine surface
Leveling, side and end screws
14 by 3.8 by 1 inches
Pros
- Stiffer and more dimensionally stable than a homemade plywood insert
- Friction screws lock the plate side to side with no wobble
- Cuts plywood
- laminate and hardwood with essentially no chip-out
- Finger hole makes removal and storage convenient
Cons
- Designed for carbide-tipped blades only
- Older saws may need light sanding for a flush fit
The Ridgid TS3650 is one of the most common cabinet-style contractor saws in North America, and the RG-1 is the insert built for it. Long-term users report durable, accurate results and a marked drop in chip-out and dust compared with factory plates or anything home-made, with fit on the intended saw reported as essentially right out of the box.
Unlike the generic inserts in this group, it comes with a full set of adjustment hardware: leveling screws, side and end adjustment screws, and a rear safety pin. The friction screws lock the plate side to side, so it does not shift under a rip cut, and the finger hole makes it easy to lift out when you need to.
Two limitations are stated plainly by the manufacturer. It is designed for carbide-tipped blades only, and older saws may need light sanding before the plate is fully flush. Both are predictable rather than alarming, and both are resolved in an afternoon.
The trade-off is dust. A full zero clearance means less dust escapes upward, which is good for the shop but reduces how effective extraction is at the opening. Owners accept this without hesitation because the cut quality gain is so much larger than the extraction loss.
Why phenolic is the right call on a TS3650
TS3650 owners tend to push the saw hard, and phenolic is the material that stays dimensionally stable when a plate is loaded. Users compare the stiffer, more stable result favourably to homemade plywood inserts, and the plate stays flush once it has been adjusted rather than drifting back out of plane.
What to expect on the first install
On a newer saw the plate should drop in and be adjusted with the side and end screws. On an older one, plan on a few light sanding passes to the sides. Keep a clean blade and expect to wipe pitch off the plate and the blade periodically, because phenolic and resin build-up travel together.
7. Peachtree UHMW Blank Insert for Ridgid and Craftsman Belt Drives
UHMW Tablesaw Zero Clearance for Craftsman/Ridgid 14″x 3-3/4″ x 3/16″
UHMW plastic blank, slot cut by you
14 by 3-3/4 by 3/16 inches
Fits Ridgid TS-2400, TS-2412, TS-2424
Pros
- Blank design lets you dial in the exact kerf for your own blade
- Works on vintage saws where no factory insert is made any more
- Quick to set up and square with the table
- Lightweight and simple to install
Cons
- UHMW is thin and flexible so it can sag and bow over time
- Included set screws fall out and are too short to hold the plate flush
- Retention screw hole is not centred so the screw cannot be used as supplied
This blank exists for a specific owner. If your saw is a Ridgid TS-2400, TS-2412 or TS-2424, or a 10 inch belt drive model from 1988 onward, you may not have a factory insert made for it any more, and this gives you a plate sized for the opening with a slot you cut yourself. That is a genuine service for a vintage saw.
Buyers like the concept and many report a clean, flush result once the slot is cut. UHMW is a slick, moisture-resistant plastic that feeds well and machines easily, and the 3/16 inch thickness is enough for a belt drive saw that is not cutting heavy hardwood.
Now the complaints, which are consistent. The material is thin and flexible, so the plate is prone to sagging and bowing over time, and the included set screws fall out and are too short to hold it flush. The retention screw hole is not centred, which means that screw cannot be used as supplied. Several owners replace or modify the hardware as part of the install.
Who this blank actually suits
It suits a vintage belt drive saw where nothing else fits, and a builder who is comfortable cutting the kerf. The trade-off is that at 4.2 stars the complaints cluster on one thing: thin flexible plastic in a slot that needs to stay flat.
Plan the hardware before you commit
Budget a few extra fasteners, or plan to reuse the saw’s existing throat plate screws. Check the plate is flat to the length before you cut the slot, because a bowed blank bakes the bow into the kerf. Owners who arrive at a flush result do it by checking flatness first, not after.
8. Skil STZ6307 OEM Insert Plate for TS6307-00
SKIL Zero Clearance Table Saw Insert Plate for SKIL Table Saw TS6307-00 – STZ6307, Multicolor
OEM plate for the SKIL TS6307-00
Adjustable height hardware
Quick-release button
Pros
- OEM part from the saw maker so the fit for the TS6307-00 is exact
- Eliminates the gap that catches small strips and keeps offcuts away from the motor
- Reduces tear-out noticeably over the stock plate
- Included hardware allows height adjustment to match the table
Cons
- Thin plastic flexes downward and can let small stock dip toward the blade
- Installation requires drilling and tapping into the saw casting
- Supplied M4 x 0.7 self-tapping screws strip easily
The Skil TS6307 is a common jobsite saw, and it is also one of the harder ones to fit an insert into because of how little material sits at the edge of the throat plate. This OEM plate is designed specifically for the TS6307-00, so it drops into the opening the way the Bosch part does on a 4100.
Owners confirm the plate fits and meaningfully improves both safety and cut quality on narrow stock, which is the problem this saw has by design. The quick-release button makes swapping between blade configurations fast, and the adjustable height hardware is what gets the plate flush to the table.
The install is the catch. This plate is fitted by drilling and tapping holes into the saw’s own aluminium casting, which is a real step up in effort and needs a proper tap and some care. The supplied self-tapping screws are M4 x 0.7 and strip easily, and owners recommend a proper tap rather than forcing them.
The other recurring note is that the plate is thin plastic, so it flexes downward under hand pressure and can let very small stock dip toward the blade. Owners also report that some cannot get the plate fully flush, and the included one-year limited warranty is the shortest in this group.
Is drilling and tapping worth it
If you own the TS6307-00 and cut narrow stock regularly, yes. Closing the gap removes the small-part problem that this saw is known for, and the OEM geometry will never be a poor fit. The trade-off is a permanent modification to the casting, which some owners are reluctant to make.
What to buy alongside it
Pick up a proper M4 x 0.7 tap and a few matching machine screws before you start, and have the plate in hand to mark hole positions before you touch the casting. Budget time to adjust the height hardware until the plate is genuinely flush, since a proud plate still catches a thin strip.
Which Insert Fits Your Table Saw?
Find your exact model number first, then match it to the plate listed against it. A plate is machined to one throat plate opening, so a close match on saw brand is not enough. If your model is not in the list below, measure the width of your opening front to back and the throat plate itself, then look for a blank insert you can cut to size yourself.
Bosch 4100, 4000, 4100XC — single blade slot, plastic OEM plate, the Bosch TS1005 drops straight in.
DeWalt DW744 and DW746 — single blade slot, phenolic laminate, the Leecraft DW-2 at 13-5/8 by 3-3/4 inches.
DeWalt 744, 745, 7480, 7491, 7491RS and 7490 — single blade slot, MDF, the CNC Custom Designs four-pack with a Type 1 slot.
DeWalt 7485 and DCS7485 — not covered by any pick here, because the four-pack explicitly excludes these models.
Delta 36-725, 36-725T2, 36-5152, 36-5000 and 36-5000T2 — single blade plus dado plate, commercial grade MDF, the ZEROSERT three-pack.
Ridgid TS3650 — single blade slot, phenolic laminate, the Leecraft RG-1 for carbide-tipped blades only.
Ridgid TS-2400, TS-2412, TS-2424 and 10 inch belt drive models from 1988 — self-cut blank, UHMW plastic, the Peachtree PW953 where you cut the slot yourself.
Skil TS6307-00 — single blade slot, OEM plate, the Skil STZ6307, which requires drilling and tapping.
Two rules before you order. First, if your saw has a riving knife or splitter permanently mounted through the throat opening, an insert with no cutouts for it will not sit flat. The CNC four-pack states this outright and will not work with the riving knife unless you modify the cutouts yourself. Second, aftermarket throat plate systems generally will not accept a plate machined for the factory opening, so check what is already fitted before you measure anything.
How to Cut the Initial Slot in a New Insert
Every insert on this list, other than the ones that ship with a pre-cut slot, gets its kerf from one operation: you run your own blade through the blank. It sounds risky and it is not, provided you respect three rules. Unplug the saw or shut it off at the breaker, wear eye protection, and never reach near a spinning blade to check the slot.
Measure the throat plate opening. Record the width front to back and the length of the plate, then cut a blank roughly 0.5 to 0.75 inch larger all round than the opening.
Use the original plate as a template. Screw, clamp or magnet the factory plate onto the blank so the blank overhangs evenly.
Set blade height correctly. With the saw unplugged, raise the spinning-free blade until the teeth clear the top of the table by about 1/8 inch. This is the cutting depth, and it also has to match your normal blade height setting for a flush cut.
Lock a sacrificial board on top. This sacrificial board is just a scrap of plywood screwed to the blank. It prevents the rising blade from grabbing and lifting the workpiece.
Restore power and raise the blade slowly. Take two or three passes, not one. The blade removes only a few thousandths per pass, and forcing it takes the twist out of the plate.
Stop, unplug, and swap the blade. Your cutting blade is dulled slightly by the pass. Lower the saw, put your normal blade back, then re-set the height to 1/8 inch of tooth exposure.
Sand the sides to fit, then level. A few light passes with abrasive paper on the side tabs bring the plate to a snug seat. Adjust the leveling screws until the plate is flush and cannot rock.
One failure mode catches almost everyone. If the blade rests on top of the insert as it rises, the plate cannot sit down to its final level and will sit proud at the front. Lower the blade fully before you set the plate, and check that nothing is caught under the plate before you tighten anything.
Insert Materials Explained: Phenolic, UHMW, MDF and Steel
Material is the biggest single decision you make, and it is where generic listings go quiet. Here is what each one actually does in a saw.
Phenolic laminate is the dense composite used by Leecraft and by the Peachtree plate. It is heavy for its size, holds its dimensions well in humidity, resists the pitch and resin build-up that ruins a blade, and takes repeated adjustment without loosening. It is the most dimensionally stable option here, and it is the only material among these that will crack if you overtighten the leveling screws.
UHMW plastic is a cheaper, softer alternative. It slides well against wood and resists moisture, but at under a quarter inch thick it is noticeably flexible. A flexible plate bows under the pressure of a rip cut, which is exactly when you need a rigid surface.
MDF is a stiff, easy-to-machine wood composite. It is the sweet spot for most home shops, and it machines identically between plates so two inserts transfer height to each other without re-leveling. Its weaknesses are honest ones: edges sand away easily, a dropped insert can chip, and a plate that arrives warped is genuinely hard to flatten.
Thin steel or plastic OEM plates are what most saws come with. They are the least rigid option and the source of the flex that makes heavy ripping feel vague. Replacing one is the single biggest quality jump available on a budget saw.
Zero Clearance Insert vs Tape vs Splitter vs Sled
Does zero clearance tape work? Partly. Tape is a strip of low-friction material you lay in the throat opening to close the visible gap. It helps a little on a cast iron or phenolic table, it does not stick reliably to a powder-coated or melamine surface, and it never closes the hole into the cabinet. It is a temporary measure, not a replacement for a machined plate.
Zero clearance insert — fixes tear-out fully, closes the drop-in risk completely, and lasts years.
Zero clearance tape — fixes tear-out only partly, does nothing for drop-in risk, and lasts a session or two.
Splitter or riving knife — does nothing for tear-out, fully solves drop-in risk, and lasts years.
Zero clearance sled — improves tear-out only while the sled is mounted, solves drop-in risk, and lasts years.
Thin sacrificial subtop — fixes tear-out, does nothing for drop-in risk, and lasts weeks.
A splitter or riving knife is a safety device that keeps the workpiece engaged with the blade. It solves the drop-in problem completely but does nothing for the underside of the cut. A zero clearance sled solves both while it is mounted, then slides off and leaves you back where you started. The insert is the only option that works every time the saw is running.
Should You Buy or Make Your Own Insert?
Making your own is a completely legitimate route, and it is more popular in forums than most sellers would like to admit. Cut a blank from MDF or plywood, take the slot-cutting steps above, and you have a working plate for the cost of a piece of sheet goods. Owners on woodworking forums describe making walnut, spruce and coated MDF plates with no problems at all, and one treats the whole thing as a consumable: make six thin ones and toss them as they get chewed up.
Buy instead if you want the adjustment hardware to be right the first time, if your saw has a thin plate edge that is hard to machine, or if you cut enough plywood to notice. The trade-off is that a homemade plate gives you no leveling screws, no anti-lift pin and no side adjustment. A three-dimensional printed plate with adjustable height screws is also reported as working, which is a useful route for saws nothing fits.
How to Choose a Zero Clearance Insert
Match the model number, not the brand. This is the whole ballgame. Every plate on this list is machined to one throat plate opening, and the two DeWalt entries in this roundup cover different saw families under the same brand name. Read the model number off the badge on your saw before you measure anything.
Measure before you order. Get the width of the throat plate opening front to back and the length of the factory plate. Compare those numbers to the listing dimensions, and be suspicious of any insert described as fitting most table saws. Forum users are blunt that vague fitment copy is the top deal breaker in this category.
Decide between single blade and dado. A single-blade insert is a slot sized to one blade. If you cut joinery, you need a separate plate for your dado stack, because a narrow slot will not safely clear a wide stack. Two of the eight picks here ship with a dado plate for that reason.
Pick material for your workload. Phenolic for stability and longevity, MDF for stiffness per cost and matched plates, UHMW for vintage saws where nothing else fits. Contractor and cabinet saws cutting thick hardwood reward phenolic. A benchtop saw cutting sheet goods is well served by MDF.
Check the riving knife situation. A saw with a permanently mounted splitter or riving knife needs a plate with matching cutouts. One pick here will not work with a riving knife as supplied, and its instructions say so explicitly.
Think about what you are cutting. If you rip thin strips or cut small parts, plate rigidity matters more than finish. If you cut veneer, the low friction surface matters. If you move the saw to job sites, weigh the plate and how it is fixed. Our cabinet table saw guide covers the heavy-work case, our professional cabinet saw picks go deeper on the same, and our outfeed table picks matter just as much once the cut is clean.
Installation and Leveling Tips
Drop the plate in with the blade fully lowered, then work the adjustment screws in small increments. Check flushness with a straightedge across the plate and the table, then check again at the front and the rear, because a plate that is level at the back can still sit proud at the front.
Two rules keep inserts intact. Never overtighten a phenolic leveling screw, because the material cracks rather than yielding, and a cracked plate is a scrap plate. And keep the blade clean. Pitch and resin build-up raises the cutting line and can stop the plate seating properly, which looks like a fit problem when it is not.
Set your blade height for about 1/8 inch of tooth exposure above the table and leave it there. Changing that setting without rechecking the plate height is the most common reason an insert starts sitting proud and catching thin stock again.
How We Chose These Inserts
This roundup is built from publicly available product data, owner review patterns and manufacturer specifications. We are not claiming hands-on testing of these plates, and we would rather say that than imply otherwise.
What we did do is weight fitment clarity above everything else, because that is where this category fails buyers. Every pick names the exact saw models it fits, and we flag the exclusions and the fit problems that owners report. Ratings and review counts are reproduced as listed. Where a complaint recurs across many reviews, we name it in the review rather than burying it.
Frequently Asked Questions
What is a zero clearance insert on a table saw?
A zero clearance insert is a replacement throat plate with a kerf slot cut to match your saw blade width exactly. Because the slot is only a few thousandths wider than the blade, the workpiece is supported on both sides of the cut, which stops tear-out on the bottom face and keeps small offcuts from dropping into the saw cabinet. It is also called a zero clearance throat plate, and is often shortened to ZCI.
Why don’t table saws come with zero clearance inserts?
Because the throat plate opening has to accept different blades. A slot cut for one blade would bind on another, so manufacturers fit a wider opening in thin pressed steel or plastic. A universal insert would sit loose in one saw and jam in another, and thin factory plates cannot be machined to a blade-specific kerf without distorting.
How do I cut the slot in a new zero clearance insert?
Cut a blank slightly larger than the throat plate opening, use the original plate as a template, and set the blade so the teeth clear the table by about 1/8 inch. Lock a sacrificial board on top, then raise the spinning blade slowly through the blank in two or three passes, since it only cuts a few thousandths per pass. Lower the saw, swap back to your normal blade, then sand the sides to fit and level the plate.
Does zero clearance tape work?
Partly, and it is a temporary measure. Tape closes the visible gap on a cast iron or phenolic table, but it does not adhere reliably to a powder-coated or melamine surface and it never closes the hole into the saw cabinet. A machined insert is the only option that addresses both tear-out and the small-parts safety problem at the same time.
Are zero clearance inserts worth it?
For most people, yes. It is the cheapest quality upgrade available on a table saw because it fixes both tear-out and the small-parts safety problem without touching the saw itself. The trade-off is that inserts are model-specific, so if you cannot confirm a plate fits your saw, making your own from MDF is a well established alternative.
Are phenolic or UHMW zero clearance inserts better?
Phenolic is stiffer, more dimensionally stable and more wear resistant, which is why it suits contractor and cabinet saws cutting thick hardwood. UHMW is cheaper, slick and moisture resistant, but at under a quarter inch it is flexible and can bow, so it suits vintage saws and light work better. Never overtighten the leveling screws on phenolic, because it cracks.
Conclusion
The best zero clearance inserts for table saws are the ones machined for your exact model, and everything else is secondary detail. Start with the Bosch TS1005 if you own a 4100 series saw, pick the Leecraft DW-2 for a DeWalt DW744 or DW746, the Leecraft RG-1 for a Ridgid TS3650, and the ZEROSERT three-pack if you run dados on a Delta.
Measure your opening before you order anything, and check whether your saw has a riving knife that needs clearance cutouts. If you are still choosing a saw rather than an insert, our beginner table saw guide is a better use of your time first. Otherwise, any of these eight plates will change how your saw cuts in 2026, and the difference shows on the very first sheet of plywood.
