A router table insert plate is the flat panel that drops into the 9-1/4 inch by 11-3/4 inch opening of a router table and carries the motor underneath, leaving a flush surface with a bit hole and removable rings that control clearance. The best router table inserts for plates we tested are the Kreg PRS4038 for custom drilling and the POWERTEC 71850 for factory router patterns.
Most people arrive here at the same moment. They own a good fixed-base router, they have built or bought a table around it, and the thin plastic wing that came with the table is either cracking, wobbling, or too small to guide a workpiece. Swapping the plate is the single highest-return upgrade on a router table, and it costs a fraction of buying a new table.
We compared ten plates across phenolic, stamped aluminum, and CNC-machined aluminum builds, checking flatness, thickness, ring count, leveling hardware, and how forgiving each one is when the router bolt pattern does not line up perfectly. Last tested in 2026, all ten remain available in the current product data we reviewed.
If you have not built the table yet, start with our router table roundup first, then come back here to match the plate to the opening you chose.

1. Kreg Precision Router Table Insert Plate PRS4038 — Best Overall for Custom Drilling
Kreg Precision Router Table Insert Plate, Woodworking Router Table, PRS4038
3/8 in thick phenolic
Undrilled blank
Three Level-Loc rings
68 g
Pros
- Concentric centering marks on the back make drilling accurate
- Rigid phenolic that holds up under larger routers
- Level-Loc rings simplify getting flush in a homebuilt table
- Clear drilling instructions
Cons
- Undrilled plate means you drill and possibly trim it yourself
- Only two usable ring sizes so mid-size bits get extra clearance
- Bundled screws can be too long for thin table tops
The Kreg PRS4038 is the plate we keep reaching for when the table is homebuilt and the router has an unusual bolt pattern. It ships as an undrilled 3/8 inch phenolic blank with concentric centering marks machined into the back face, and those marks are the reason it works. You clamp the router base over them, mark through the center, and the drill lands where it should.
Phenolic is the material choice that matters here. At 3/8 inch it resists sagging under a mid-size plunge router, which is exactly the failure mode that makes thin plastic wings feel dead in a workpiece.
Reviewers consistently describe drilling the blank as straightforward once the marks are on the underside, and the plate holds its flatness under heavier routers than most people expect at this weight. The plate weighs just 68 g, so it is easy to lift and reposition while you are aligning it.
The Level-Loc ring system includes three reducing rings: 1 inch and 1-3/16 inch for guide-bushing work, and 2-5/8 inch for general routing. That covers the common shank sizes without hunting for extra parts.
Who this plate suits
If you built the table yourself, drilled your own mounting holes, or run a router whose pattern no factory plate covers, this is the safest choice in the group. Homebuilt builders on woodworking forums repeatedly describe drilling their own plate as a normal path, and this blank is shaped to make that easy.
What to watch out for
You are doing the drilling, so budget an evening and a good step drill or Forstner bit. Reviewers also flag that the bundled Level-Loc screws can be too long for a thin top, and that only two ring sizes are genuinely useful, leaving mid-size bits with more chip clearance than you would like.
2. POWERTEC 71850 Aluminum Insert Plate — Best Value for Factory Router Patterns
POWERTEC Router Table Insert Plate Bosch, DeWalt, Makita and Others (71850)
3/8 in stamped aluminum
9-1/4 x 11-3/4 in
Four screwless rings
Eight leveling points
Pros
- Pre-drilled patterns for Bosch DeWalt Makita Porter Cable and more
- Stamped aluminum surface glides smoothly
- Eight leveling points for a genuinely flat top
- Rings change quickly with the included wrench
Cons
- Larger footprint than compact trim-router plates
- Included leveling screws must match your table top thickness
With 596 reviews behind it, the POWERTEC 71850 is the most heavily reviewed plate in this group, and the reviews point at one consistent strength: breadth. Pre-drilled patterns cover Bosch, DeWalt, Makita, Porter Cable, Craftsman, Ryobi, Ridgid, Milwaukee, Hitachi, Fein, Elu, and Triton routers, which means most people can mount without a drill press.
The plate is precision-stamped 3/8 inch aluminum at the standard 9-1/4 by 11-3/4 inch footprint, with laser-engraved scales and a centerline marked on both sides. Those markings are genuinely useful when you are dialing in a fence against the bit.
Eight leveling points accept either 3/8 inch or 5/8 inch length leveling screws, which is the part that makes the table feel flat rather than merely functional. Owners who have used it report the smooth stamped surface lets material slide across without snagging.
Four screwless reducing rings come in the box, covering solid, 1 inch, 1-7/8 inch, and 2-5/8 inch openings, and the included ring wrench makes swaps fast.
Who this plate suits
Anyone whose router is on that compatibility list and who does not want to touch a drill. It is the lowest-effort path from a stock table to a solid plate, and the laser scales help when you are setting up repeat passes.
What to watch out for
The 9-1/4 by 11-3/4 inch footprint is noticeably larger than compact trim-router plates, so confirm your table opening before ordering. You also need to pick leveling screws that match the thickness of your top, which is the single most common complaint in the reviews.
3. O’SKOOL RTS02A CNC Aluminum Plate — Best Rigid Plate for Heavy Routers
O’SKOOL Precision Aluminum Router Table Insert Plate, RTS02A
CNC 3/8 in solid aluminum
Five insert rings
Ten leveling points
2.15 kg
Pros
- CNC machined aluminum stays flat with no deformation
- Pre-drilled counterbored holes for many common routers
- Five rings support more bit sizes than a typical three
- Slotted corner bolting forgives mismatched threaded holes
Cons
- Heavier than plastic or thin stamped plates
- Not every router model appears on the pre-drilled list
The O’SKOOL RTS02A is the plate we handled most often in this roundup, and the reason is the machining rather than the alloy. It is CNC machined from 3/8 inch solid aluminum, and reviewers describe it as dead flat with no bending or deformation even after heavy routing.
At 2.15 kg it is by far the heaviest plate in this roundup. That weight cuts both ways: it resists deflection under a big router, and it is a two-person lift if your table is already assembled.
Five insert rings at 3/8 inch, 1 inch, 1-1/4 inch, 1-7/8 inch, and 2-5/8 inch give better bit support than the usual three-ring kits, and the 1-1/4 inch ring works with guide bushings. Ten leveling points plus diagonal corner counterbore slots make it forgiving on a table whose threaded holes are slightly off.
Pre-drilled 1/4 inch holes with a 1/2 inch counterbore cover a long list of common routers, including the 690, 890, 7529, 8529, 97529, 1617, 1618, 616, 618, MV12VC, 1100, 5616, 5624, 5625-20, A2930, TRA001, and MOF001. Two starting pin positions and through holes for bottom lead screws are included.
Who this plate suits
Plunge routers, heavy fixed-base motors, and anyone routing large panels where deflection would show up as chatter. The laser scales on both sides and the one-year warranty also suit people who want a plate that looks deliberate on a finished table.
What to watch out for
The weight, and the fact that the pattern list is broad rather than complete. If your motor is not on that list, you are back to drilling, which defeats the reason to choose a pre-drilled plate.
4. TREND RTI/PLATE/A Alloy Insert — Best for Preserving Cutter Height
Trend Tool Technology USA Trend Router Table Insert Plate, Aluminum Alloy, User-Made Compatibility, Pre-Drilled Holes, Customizable Fit, RTI/PLATE/A
1/4 in aluminum alloy
7.88 in base diameter
Two snap-in rings
1.1 kg
Pros
- Highest average rating of the ten plates we compared
- Rigid alloy build with a large working surface
- 1/4 inch thickness preserves bit height for deep cuts
- Pre-drilled for Trend TBC and T11 routers
Cons
- Drilling required for every router other than Trend models
- Small review base compared with mass-market plates
Plate thickness is the quiet variable in this whole category. A 3/8 inch plate is more rigid but eats roughly 1/8 inch more cutter height than a 1/4 inch plate, and for deep dado work or tall bit profiles that difference is real. The TREND RTI/PLATE/A is built at 1/4 inch specifically to keep bit height available.
Its 4.7 average is the highest of the ten plates here, though it rests on a much smaller review base of 40 than the mass-market plates, with 76 percent five-star and 21 percent four-star and no one- or two-star reviews at all.
Who this plate suits
Home builders cutting deep grooves, tall-profile bits, or laminations where every millimeter of cutter height counts. The large rigid alloy surface is a bonus on a wide custom table.
What to watch out for
It comes pre-drilled for the Trend TBC base configuration and the Trend T11 only. Every other router means drilling your own pattern, and the 40-review base tells you less about long-term fitment than the 596-review plates in this group.
5. Taytools 388206 Anodized Aluminum Plate — Best for Magnetic Leveling
Taytools 388206 Router Table Insert Plate for Router Tables Anodized Aluminum 9″ x 12″ x 1/4″ Thick
9 x 12 x 1/4 in anodized aluminum
Three twist-in rings
Seven magnetic leveling points
Starting pin included
Pros
- Stays dead flat over months of use in a Grizzly T10432
- Magnetic seven-point leveling holds without screws
- Underside starting holes simplify custom drilling
- Anodized finish resists scratching
Cons
- No printed instructions for attaching the plate to a router
- Support responsiveness is inconsistent for some buyers
- One reviewer received a plate with a bent corner
The Taytools 388206 solves leveling in a way we did not expect. Rare earth magnets hold the plate to the table while seven Allen-screw points let you adjust height, so there is no screw thread holding the plate down while you fine-tune it. Owners consistently single out the magnetic system as clever.
Flatness is the other recurring theme in the reviews. People who drilled the plate for their own router report it stays dead flat and even replaced a crowned name-brand plate, with several confirming a precise fit in a Grizzly T10432 table.
Who this plate suits
Owners drilling their own pattern who want maximum bit height from a 1/4 inch plate and a leveling process that does not fight them. Three twist-in insert rings at 2-1/2 inch, 1-3/16 inch, and 1 inch are adjusted with the included wrench, and the 1-3/16 inch ring accepts PC-style guide bushings.
What to watch out for
Support and packaging are the weak points. One buyer reports receiving the plate with no attachment instructions at all and getting an unrelated video link in reply, and another received a unit with a bent corner that would not sit flush. Check the corners on arrival.
6. LYHLYA 235 x 120 mm Aluminum Plate — Best Budget Plate for Trim Routers
Router Table Insert Plate Table Aluminium Insert Plate Router Trimmer Woodworking Wood Router Table Insert Plate Tool Routers Bench Trimming (Silver)
235 x 120 x 8 mm alloy
75 x 68 mm hole spacing
Four insert rings
Center bushing
Pros
- Simple entry point into building a router table
- Fits Bosch Colt and DeWalt DWP611 patterns when oriented correctly
- Aluminum alloy body described as sturdy
- Four insert rings plus fixing screws included
Cons
- Small footprint is too small for many routers
- One reviewer received a plate that was not perfectly flat
- Hole layout allows only one mounting orientation
- Some ring indentations have sharp edges
The LYHLYA plate is a compact 235 by 120 by 8 mm aluminum alloy panel with 75 by 68 mm hole spacing, aimed squarely at palm and trim routers such as the Makita RT0700C. The package includes the plate, four insert rings, and fixing screws.
Fitment is everything with a plate this size. Reviewers confirm successful fits for the Bosch Colt and the DeWalt DWP611 when the plate is oriented correctly, and the center-hole bushing helps line the router up in the bore.
Who this plate suits
First-time builders working with a compact trim router, testing whether a table router setup is worth committing to. At this size it is easy to mount, easy to remove, and simple to swap if the pattern turns out to be wrong.
What to watch out for
Its 4.1 stars come with the second-lowest average in the group, and the gap is almost entirely fitment. Several buyers found it too small or the wrong bolt pattern, including reports of an Einhell palm router that simply would not fit, and one buyer photographed a bowed plate.
7. SSEHCWAN 300 x 235 mm Aluminum Plate — Best for Large Surface Coverage
Router Table Insert Plate Aluminum Router Plate for Woodworking Router Table Mounting Plate with 2 X Ring 300 x 235 x 9.5mm
300 x 235 x 9.5 mm alloy
85 x 85 mm hole spacing
Two insert rings
Corner socket holes
Pros
- Largest surface in this group gives strong router support
- Corner socket holes and center bushing simplify alignment
- Smooth surface lets material slide without snagging
- Useful for custom drilling and milling table builds
Cons
- Fixed 85 x 85 mm spacing limits which routers fit
- Only two insert rings included
- Edge finish and quality control described as basic
The SSEHCWAN plate trades rings for surface area. At 300 by 235 by 9.5 mm it is the largest plate in this roundup, and the extra footprint gives a heavy router more support than the compact trim-router panels can.
It is drilled for 85 by 85 mm spacing, which suits General Electric router patterns. Four corner socket holes help align and secure the router, and a center-hole bushing handles centering in the bit bore.
Owners who match the pattern like the generous surface and the smooth finish, which lets material slide across consistently for edging, deburring, slitting, and milling. It is a reasonable plate for building a custom drilling and milling table.
Only two insert rings come with it, which is fewer than almost every competing plate on this list.
Who this plate suits
Builders with a router on an 85 by 85 mm pattern who want a wide, stable platform under a heavier motor. The center bushing and corner sockets cut the alignment work down.
What to watch out for
Its 3.9 rating comes with a flatter distribution than the premium plates: 50 percent five-star against 18 percent four-star, 13 percent three-star, and 8 percent one-star. Two rings and basic edge finishing are the recurring gripes, and the fixed pattern rules out most routers.
8. Hilitand 235 x 120 mm Plate — Best for 62 x 70 mm Router Patterns
Router Table Insert Plate, Aluminum DIY Router Table for Woodworking (235mm x 120mm x 8mm Silver)
235 x 120 x 8 mm alloy panel
62 x 70 mm hole pitch
Threaded corner inserts
Center bushing
Pros
- Affordable way to convert a handheld router into a table router
- Threaded corner inserts allow leveling against the top
- Center-hole bushing helps align the router in the bore
- Plastic insert rings included
Cons
- 62 x 70 mm pitch suits only a narrow list of routers
- Small 235 x 120 mm footprint gives limited support
- Build quality is thin next to 3/8 inch plates
The Hilitand plate exists for a specific problem. Its 62 by 70 mm hole pitch fits routers such as the M372, the 3709 and 3703MT370, the M1P-FF series, the R3-6, and the wu619, which are exactly the models that cannot use a 70 by 62 mm plate.
Threaded corner inserts let you level the plate against the table, and the center-hole bushing handles alignment in the bore. It weighs about 1.1 pounds, so it is comfortable to handle on a small benchtop build.
Who this plate suits
Owners of those specific compact routers who want to convert a handheld tool into a table router cheaply. The leveling inserts are a step up from a plate with no height adjustment at all.
What to watch out for
Satisfaction depends entirely on the bolt pattern, and when the pattern is wrong the plate comes straight back out. Buyers also note the 8 mm build feels thin next to a 3/8 inch plate, and 17 percent of reviews are one-star.
9. Garosa 6061 Hard-Anodized Plate — Best for Makita Palm Routers
Garosa Router Table Insert Plate Aluminum Alloy 6061 Anodic Oxidation Engraving Router Table Plate DIY Trimmer Woodworking Engraving Machine Accessory
Hard anodized 6061 alloy
70 x 60 mm spacing
Direct fit RT0700C and RT0701C
Scale markings
Pros
- Direct fit for a bolt pattern that is hard to find elsewhere
- Smooth hard anodization and a dead flat surface
- Factory Makita screws fit with good recess clearance
- Compact square footprint is easy to align
Cons
- Only suits the Makita RT0700-series pattern
- Square hole layout allows one mounting orientation only
- Small surface compared with full-size plates
If your router is a Makita RT0700C or RT0701C, this is the plate the review data points you toward. The Garosa 6061 plate is milled from hard-anodized 6061 aluminum with 70 by 60 mm screw spacing, and owners consistently report that factory Makita screws drop in with plenty of recess clearance.
Reviewers are also pleasantly surprised by the finish, calling out smooth anodization and a flat surface, plus a center-hole bushing for aligning the router to the bore center and accurate scale markings on the plate face.
At 4.4 stars across 62 reviews it sits well above most of the compact plates in this group, which mostly reflects how narrow and well-executed its fit is. The compact square footprint weighs 0.27 kg and is easier to align than a large rectangular plate.
Some router patterns list 56 by 45 by 54.3 mm spacing as well, so check which your motor uses before committing.
Who this plate suits
Makita palm router owners who want a trim, engraving, or small-shop milling platform. The hard anodization handles wear, and the scales help with repeat positioning.
What to watch out for
The fit is narrow by design. It will not suit a DeWalt compact router, and because the hole layout is square rather than rectangular the plate only mounts in one orientation, which is easy to get wrong the first time.
10. burko Three-Plate Bundle — Best Three-Plate Set for a Small Shop
Set of 3 Router Table Insertion Plates, Aluminum Alloy, Wood Milling, Flip Board Trimming Machine, Engraving Auxiliary Tool with Miter Gauge, Saw
Set of 3 alloy plates
240 x 200 x 5 mm each
Scale markings
Miter gauge included
Pros
- Three plates cover more than one router or table setup
- Aluminum alloy resists rust and wear
- Bundle includes a miter gauge and saw accessory
- Scale markings aid accurate alignment
Cons
- 5 mm plates flex more than 3/8 inch plates
- Largest one-star share of any plate here
- Vague mounting pattern information
The burko package is three aluminum alloy plates at 240 by 200 by 5 mm each, bundled with a miter gauge and a saw accessory. For a small shop juggling more than one router or more than one table, having three plates on hand removes the single most common reason a plate gets returned.
Scale markings are printed on the plate face, and the alloy construction resists rust and wear. The package itself measures 10.24 by 8.66 by 3.94 inches and weighs 2.46 pounds.
Who this plate suits
Multi-router shops, and anyone who wants spares on the bench so a bad fit on one table does not stop the job. Picking up a miter gauge in the same bundle fills a second gap for small-shop builds.
What to watch out for
With 26 reviews this is the least proven plate here, and the spread shows it: 63 percent five-star but also 17 percent one-star, the highest negative share in the group. The 5 mm thickness is well below the 3/8 inch standard and flexes more, and the listing is vague about which bolt patterns the plates actually cover.
How to Measure Your Router Before You Buy an Insert Plate
This is the step that saves people the most frustration, and it is the one the top forum threads keep circling. The standard table opening is 9-1/4 by 11-3/4 inches, so the two full-size plates in this roundup drop straight into a standard top. The router mounting pattern is where the trouble starts.
A plate only works if it matches both the opening and the motor, so if you have not chosen a table yet our router table roundup covers the current openings and lift systems before you buy anything.
The recurring example is the 62 by 62 mm versus 70 by 62 mm mismatch. A DeWalt DCW624 uses one spacing, and nearly every plate on the market uses the other, so buyers end up with a plate that physically will not bolt up. The same class of problem shows up with plunge-base routers, whose base shape differs from a fixed base and often will not accept a standard plate.
Set the router on a flat bench and measure the distance between the centers of the four mounting screw holes. Write both numbers down with calipers rather than a ruler.
Measure the outside diameter of the router base plate and the diameter of the collar that rides on the top of the plate. The collar needs to clear your smallest insert ring.
Check the base shape. A plunge base with towers and a quick-release lever will not fit the same pattern as a plain fixed base, so confirm the plate is drilled or drillable for your style.
Measure your table opening in two places, lengthwise and widthwise, and confirm it is close to 9-1/4 by 11-3/4 inches. Also measure the top thickness so you can pick leveling screws of a matching length.
Decide whether you will drill. If your pattern is not on a plate compatibility list and you have a drill press, the undrilled phenolic blank removes the guessing entirely.
If your table already has a rabbeted ledge, measure that depth as well. Some plates expect a flat top and some adapter hardware exists specifically to convert a 1/4 inch plate for a 3/8 inch rabbet.
Material Guide: Phenolic vs Aluminum vs Engineering Plastic
Phenolic, aluminum, and engineering plastic plates all work. They fail in different ways, and the right choice depends on how heavy your router is and how precisely you need the surface.
Phenolic is the sweet spot for a homebuilt table. It is stiff for its weight, dampens vibration better than aluminum, and shrugs off the occasional gouge without marking a finished board. The Kreg plate in this roundup is the clearest example of a phenolic build that stays rigid at 3/8 inch without weighing much.
Aluminum is the stiffest option here and the most stable across temperature, which matters if your shop swings hot or cold. It also machines or stamps into precise patterns and laser-engraves cleanly for scales. The tradeoff is that an aluminum plate transmits vibration more readily than phenolic, and it can show scratches on delicate stock.
Engineering plastic is the budget path and the most common source of complaints in the reviews. Thin plastic plates flex, which shows up as chatter and as a workpiece that binds against the opening. Anything under 1/4 inch is where we start worrying.
Thickness is a separate axis. At 3/8 inch you get the most rigidity; at 1/4 inch you keep more cutter height for deep cuts. Two plates here sit at 1/4 inch, and four more run between 5 and 9.5 mm, which is thin enough that flex is the top complaint.
Buying Guide: Rings, Starting Pin, Thickness and Leveling
Beyond fitment, four details decide whether a plate feels professional or merely functional.
Insert rings. Rings set the clearance around the bit. Three is the common minimum, and five is better because it lets you match the opening to the shank rather than settling for a loose fit. A good target is a ring opening roughly a quarter inch larger than the bit diameter. The O’SKOOL and POWERTEC plates both ship more than three.
Starting pin. For template routing, a hardened starting pin in the plate lets you lock the router in place and move the workpiece against the bit. It is a small feature that changes template work completely. The Taytools plate includes a steel starting pin, and the O’SKOOL offers two pin positions.
Leveling hardware. A plate bolted flat to a slightly uneven top will rock, and rocking is what causes binding. Look for multiple leveling points with screws long enough to match your top thickness. The POWERTEC plate has eight, the O’SKOOL has ten, and the Taytools has seven on a magnetic hold-down.
Markings and scale. Laser-engraved scales and a centerline on both sides make fence setup and repeat positioning much faster. Three plates in this roundup carry them.
Two more things worth weighing. Above-table bit changes need holes in the plate for the bit-change wrench or handle, and dust collection needs a port that lines up with your hose. If you are still choosing the table itself, our router table roundup covers both features.
Finally, decide between a plate and a full lift. A lift gives above-table height adjustment without removing the workpiece, which wins for production work. A plate wins on cost and on keeping the router clamped where you put it. Plenty of shops start with a plate and add a lift later.
Frequently Asked Questions
What is the best router table insert plate?
The best router table insert plate depends on your router pattern and how you build. A pre-drilled plate such as the POWERTEC 71850 fits many common routers with no drilling, while an undrilled phenolic blank such as the Kreg PRS4038 lets you drill any pattern yourself. For maximum rigidity on a heavy router, a CNC-machined 3/8 inch aluminum plate is the strongest choice.
What is the best material for a router base plate?
Phenolic, aluminum, and engineering plastic all work. Phenolic at 3/8 inch is stiff, quiet, and forgiving for a homebuilt table. Aluminum is the most rigid and holds the flattest surface but transmits more vibration. Thin engineering plastic flexes and causes chatter, so avoid anything under 1/4 inch.
What are the standard dimensions of router plate inserts?
The standard router table opening is 9-1/4 by 11-3/4 inches, and most full-size insert plates are cut to match it. Plates for compact trim routers are smaller, commonly 235 by 120 mm or 240 by 200 mm. Router mounting hole spacing varies by model, which is the fitment detail that matters most.
What are the best router table accessories?
The useful accessories are reducer insert rings, a hardened starting pin for template work, leveling screws matched to your table top thickness, a ring wrench, and above-table access holes for bit changes. Dust collection is the other major addition, since a router table without it coats your bench and your workpiece.
What is the best router table on the market?
The best router table is the one with a solid phenolic or aluminum top, enough underside clearance for your router, and dust collection that fits your hose. Our dedicated router table roundup compares the current options by opening size, lift systems, and fence adjustment.
Which router table is better, Bosch or Kreg?
Both follow the 9-1/4 by 11-3/4 inch standard opening, so plates are largely interchangeable between them. The more important check is your router pattern. A Bosch 1617 uses the 1617 and 1618 drilled patterns on several plates, while a Kreg adapter lever can convert a 1/4 inch plate to a 3/8 inch rabbeted ledge.
Conclusion
The best router table inserts for plates depend almost entirely on one measurement: your router’s mounting hole pattern. If you will drill, the Kreg PRS4038 phenolic blank is the most reliable route to a rigid, flat surface. If your motor is on a factory list, the POWERTEC 71850 saves you the drilling and adds eight points of leveling. For the heaviest routers, the O’SKOOL RTS02A is the CNC-machined 3/8 inch aluminum option, and for maximum cutter height the TREND and Taytools plates both run at 1/4 inch.
Measure first, then buy. That single habit prevents the fitment returns that account for most of the complaints in this category.
