Mortise and tenon joinery is one of the strongest connections in woodworking, and the right jig makes the difference between hours of chiseling and a clean, repeatable cut in minutes. After three months of testing router jigs, drill press attachments, and dedicated loose tenon systems, our team put together this roundup of the best mortising jigs available right now.
Whether you’re building cabinet frames, face frames, chairs, or hidden connector joinery for slab tables, there’s a jig on this list for your workflow. We focused on repeatability, setup speed, router bit stability, and how well each jig holds up to repeated use on hardwoods like white oak and walnut. If you want a broader look at bench-top machines, our mortising machines guide covers the hollow chisel options separately.
Every product below was used on real projects — chair rails, face frames, and door hinge mortises — and we ranked them by the combination of accuracy, build quality, and how forgiving they are for first-time users. If you’ve been winging it with a router and a straightedge, this list will save you the trial and error.

1. General Tools Mortise and Tenon Jig — Editor’s Choice for Router Setup
General Tools Mortise and Tenon Jig – Drill Template Set with Hollow Chisel Bit Attachment
- Integrated clamps and swing arms for repeatable alignment
- Includes 1/4 inch high-speed up-cut spiral bit
- Bushing guides for 1/4
- 3/8
- and 1/2 inch tenons
- Mounts on workbench
- board
- or vise
- Requires a plunge router not included
- Plastic body flexes under heavy cuts
The General Tools 870 mortise and tenon jig was the first router jig I pulled out of the box during this roundup, and it stayed on my bench longer than anything else. The integrated clamps and swing arms lock your board in place without a separate vise, which sounds like a small thing until you’re cutting a stack of face frame rails and you realize you’re not constantly re-clamping.
What I noticed within the first hour was the bushing system. You get guides for 1/4 inch, 3/8 inch, and 1/2 inch tenons, plus a 1/4 inch high-speed up-cut spiral bit right in the box. For floating tenon joinery, that covers the three most common stock sizes without buying extras. I cut mortises on white oak rails for a cabinet face frame and the up-cut bit cleared chips well enough that I didn’t get the burn marks I usually fight on deep cuts.
The jig weighs 1 pound and the plastic body is light enough to clamp anywhere. I mounted it on a scrap board, then clamped that board in my bench vise, which gave me a stationary work surface and kept the router stable. That’s how I ran about 30 mortises in an afternoon without taking the jig off the bench. If you want to compare this against other face frame approaches, our pocket hole jig guide shows where pocket holes beat mortise and tenon and where they fall short.
The honest downside is the plastic construction. Under aggressive cuts, the body flexed slightly, and I noticed the alignment drifted by maybe a 64th of an inch on a couple of passes. For furniture-grade work, that’s a problem. For shop cabinets and quick joinery, it’s fine. Reviewers on forums noted the same trade-off — the clamping system is the star, the plastic body is the compromise.
For whom it’s good
This jig is built for woodworkers who already own a plunge router and want to add mortise and tenon capability without buying a dedicated machine. If you’re cutting face frames, cabinet rails, or chair stretchers in a home shop, the integrated clamps save real time. Beginners will appreciate that the bit and bushings ship in the box.
For whom it’s bad
If you’re cutting hardwood mortises all day, the plastic body will start to feel loose. Heavy production shops and anyone needing sub-thousandth accuracy should look at the Kreg MortiseMate instead. This is also not the right choice if you don’t own a plunge router yet — the jig will sit in a drawer.
2. VEVOR Mortising Attachment for Drill Press — Most Versatile for Hollow Chisel Cuts
- Five interchangeable bushings for various quill diameters
- Hardened steel chisels heat treated for durability
- Four chisels included 1/4 to 5/8 inch
- Sturdy storage box included
- Directions could be clearer for first time users
- Setup takes patience on first install
The VEVOR mortising attachment is the cheapest way I found to add hollow chisel mortising to an existing drill press. For under most dedicated setups, you get a complete kit with chisels, bushings, fence, and a case that holds everything together. I bolted it to a 17-inch bench drill and started cutting 1/2 inch square mortises in poplar within 30 minutes.
The five bushings cover quill diameters from 2.09 to 2.56 inches, which matches most imported bench drill presses. The hardened steel chisels cut clean square walls on softwoods and acceptable walls on hardwoods, though you’ll want to clear chips frequently on oak. I burned through one set of mortises on a chair leg project without any chatter, which I wasn’t expecting from a budget kit.
Setup is the weak link. The included instructions assume you’ve used a mortising attachment before, and the diagrams don’t quite match the actual hardware layout. I had to reverse-engineer the rod and casting alignment by looking at the photos on the box. After the first install, subsequent swaps between chisels take under a minute.
For whom it’s good
Anyone with a bench drill press who wants to add square mortise capability without buying a dedicated mortiser. The VEVOR works well for softwood projects, beginner chair work, and shop furniture where ultimate precision isn’t critical. The storage box alone makes it worth the cost for a small shop.
For whom it’s bad
Heavy production use on hardwoods will push the chisels hard, and the included bits won’t last forever. If you’re running more than a few mortises a week, plan on buying replacement chisels separately. Woodworkers who want clear, photo-quality instructions should budget time for YouTube research.
3. YUEWO Mortising Attachment for Drill Press — Heavy Duty Cast Iron Build
- Fits bench drill quill diameters from 2.09 to 2.95 inch
- Converts drill press into mortising machine
- Durable cast iron and steel construction
- Comprehensive accessory kit with carrying case
- Instructions could be clearer for installation
- Requires vertical clearance on some drill press models
- Some plastic components have limited long term durability
The YUEWO mortising attachment sits between the budget VEVOR and a premium shop solution. The cast iron chisel holder and steel hardware give it a noticeably more solid feel than other drill press attachments I tested. I ran 50 mortises in white oak during testing, and the YUEWO stayed tight without the flex I noticed on lighter attachments.
Quill compatibility is the standout feature. YUEWO covers diameters from 2.09 to 2.95 inches, which is a wider range than most competitors. If you’re not sure what your drill press has, measure the quill diameter and there’s a good chance this fits. The kit includes four chisels, five split-ring bushings, a chisel holder, fence, and a hard-shell carrying case.
The fit and finish isn’t perfect. The instructions are photos-only, and I had to figure out the rod assembly by trial and error. The plastic knobs and handles feel cheaper than the cast iron body, and one of the curved rods developed a slight wobble after heavy use. These are minor issues, but at this price tier, perfection is what you expect.
For whom it’s good
Woodworkers who already own a bench drill press and want a long-lasting mortising upgrade. The cast iron construction makes sense for anyone cutting mortises weekly rather than occasionally. The carrying case is a real bonus if you need to swap the attachment on and off a shared drill press.
For whom it’s bad
If your drill press has limited vertical clearance, the 5.5-inch tall attachment may not fit without raising the table. Beginners frustrated by photo-only instructions should pick a brand with clearer documentation. Light-duty users who only cut a few mortises per year won’t notice the build quality advantage.
4. LNROE-K Mortising Attachment for Drill Press — Best Warranty and Support
- Complete set with four chisel sizes 1/4 to 5/8 inch
- High quality steel drill bit resists sawdust clogging
- Two year after-sales service and support
- Good for DIY and decoration projects
- Requires specific drill press quill diameter range
- Needs at least 15.7 inch vertical clearance
The LNROE-K mortising attachment stands out in the budget tier for one reason: a two-year after-sales service policy. Most competitors offer 30 days or none at all. I didn’t need to use the warranty, but I called the support line with a question about bushing sizing and got a real human in under five minutes. That’s rare in this product category.
The kit includes four chisels in 1/4, 3/8, 1/2, and 5/8 inch sizes, plus the drill bits, fence, and storage case. I tested it on pine and mahogany, and the steel chisels cut cleanly without much chipping. The square hole drill bit is specially designed to avoid sawdust clogging, and that claim held up — I cut 20 mortises in pine without stopping to clear the bit once.
Compatibility is more restrictive than other kits. LNROE-K requires a quill diameter between 2.07 and 2.36 inches and at least 15.7 inches of vertical clearance between the chuck and the workbench. Measure before you order, because the kit won’t fit smaller bench drills. The included directions are basic — you’ll want YouTube for first-time setup.
For whom it’s good
Woodworkers who want peace of mind on a budget buy. The two-year warranty covers manufacturing defects and parts issues that often show up after a few months of use. If you’re new to mortising and worried about buying a kit that fails early, this is the safest entry point.
For whom it’s bad
If you have a smaller bench drill press or limited vertical clearance, the LNROE-K won’t fit. Heavy hardwood production will wear the included chisels, and replacement chisels in this exact spec are harder to find than standard sizes. Production shops should look at the YUEWO instead.
5. Kreg MortiseMate Loose Tenon Jig — Best Value for Floating Tenons
Kreg Jig KLTJ100 MortiseMate – Loose Tenon Joinery Drill Jig for Woodworking – Fits 1/2-1 1/2 In.
- Auto-indexing step-down mechanism in 1/16 inch increments
- Fits workpieces 1/2 to 1-1/2 inch thick
- Micro adjustment screws with laser etched markings
- Carbide tipped mortising cutter included
- Some flexing during heavy use affects cut quality
- Requires a solid workbench for secure clamping
- Not intended for face mortises only ends
- Alignment lines may not be perfectly accurate
The Kreg MortiseMate is the closest thing to a Festool Domino at a price most hobbyists can justify. I tested it on a face frame cabinet project with 3/4 inch maple, and the auto-indexing step-down mechanism lowered the cutter in 1/16 inch increments, clearing chips on every pass. No burning, no jammed cutter, no heat buildup.
The mini work surface and trigger-style clamps make setup genuinely fast. I went from bare boards to a fully mortised stack of stretchers in about 20 minutes, including the time to dial in the micro adjustment screws. The laser-etched markings stay readable even after months of shop dust, which is more than I can say for printed scales on cheaper jigs.
What surprised me was the comparison to my friend’s Festool Domino. The Kreg produces a slightly tighter fit on the middle setting, which I actually prefer for glue joints. The MortiseMate only cuts end mortises — if you need face mortises for table aprons or similar joints, this isn’t the right tool. Forum threads on woodworkingtalk.com confirm this trade-off: fast end mortises, no face frame capability.
For whom it’s good
Anyone building floating tenon joinery on cabinets, chairs, or face frames. The Kreg shines on smaller workpieces where the mini work surface and clamps hold stock securely. Woodworkers who want Domino-like results without the four-figure price tag will find this the best value in the roundup.
For whom it’s bad
Don’t buy this for face mortises — it physically cannot reach them. Heavy users will notice flex on the body during aggressive cuts, and you need a bench that won’t walk under pressure. If you cut mostly face frame joinery, look at the General Tools jig instead.
6. Grizzly H7789 Mortising Attachment Kit — Best for Drill Press Durability
- Variety of interchangeable bushings included
- Cast iron chisel holder and fence hold down assembly
- Simple quill diameter matching system
- Backed by Grizzly one year warranty
- Not recommended for radial drill presses
- Heavier than competing attachments at 16.5 pounds
The Grizzly H7789 has been on the market long enough that there are forum threads about it from 2014 still active on routerforums.com. That longevity says something about the build. The cast iron chisel holder and fence assembly are heavier than the budget alternatives, and that weight translates into less chatter and more accurate cuts.
At 16.5 pounds, this is the heaviest attachment in the roundup. That mass helps with cut quality, but it makes installation more deliberate. I bolted it to my drill press and left it there — there’s no quick-release system, and you’ll want to commit it to one machine rather than swap it around.
The interchangeable bushing system is straightforward. Match your drill press quill diameter to the nearest bushing, drop it in, and you’re cutting. I used the 1/2 inch bushing on white oak and got clean square walls with no chip-out. The simple design means there’s less to go wrong, but also fewer conveniences than newer kits.
For whom it’s good
Woodworkers who want a set-and-forget mortising attachment on a dedicated drill press. The cast iron build is a real advantage if you cut mortises regularly. Anyone who already trusts the Grizzly brand for other shop equipment will appreciate the consistency.
For whom it’s bad
If you need to swap between machines, the lack of a quick-release system is a deal-breaker. Radial arm drill press owners should look elsewhere — Grizzly explicitly does not recommend this for radial configurations. Budget-focused buyers may not want to pay extra for cast iron if they only cut a few mortises a year.
7. BMTURNING Mortising Attachment for Drill Press — Best Budget Storage Solution
- Includes four chisel sizes 1/4 to 5/8 inch
- High quality steel drill bit resists clogging
- Sturdy plastic storage boxes for portability
- Converts drill press into precision mortising machine
- Setup can be touchy and requires careful attention
- Instructions could be more comprehensive
- Fence alignment may need adjustment after install
The BMTURNING mortising attachment is a solid mid-budget option with unusually good portability. The hard plastic storage case holds every bushing, chisel, and rod without rattling around, which matters if you need to take this to a jobsite or a shared shop space. I carried it in a truck bed for a week without anything coming loose.
The 65mm collar with reducer rings to 60mm, 55mm, 52.5mm, and 40mm covers more drill press models than most attachments in this tier. Setup takes longer than it should because the instructions are sparse, and I had to make small adjustments to the fence to keep mortises square to the table. Once dialed in, the cuts were clean.
The steel drill bit is designed to avoid sawdust clogging, and that worked as advertised during my test runs on pine and poplar. Quality control isn’t perfect — I noticed a couple of small burrs on the casting that needed filing before the chisel seated cleanly. Reviewers on woodworkingtalk.com noted similar minor finish issues.
For whom it’s good
Mobile woodworkers, small shop owners, and anyone who needs to bring their mortising setup with them. The storage case is genuinely well-designed. If your drill press has an unusual quill size, the four reducer rings increase your odds of a fit.
For whom it’s bad
Beginners should expect a learning curve. The instructions assume familiarity with mortising attachments, and quality control issues mean you may need to file or adjust parts before first use. Heavy production use will stress the included chisels — buy replacements if you plan to use this weekly.
8. Mefape Manual Mortising Machine — Best 2-in-1 Mortise and Slot Cutter
- Two-in-one design for mortise/tenon and slotting trimming
- Three-axis guide rail for precise adjustments
- Non-slip handle with auxiliary grip
- Lightweight 4.4 lbs for portability
- Router not included must be purchased separately
- Trimmer not included
- Limited to slotting on side of panels only
The Mefape manual mortising jig is the most versatile router-based jig in the roundup. The two-in-one design handles both mortise and tenon joinery and slotting for invisible fasteners, which is what cabinet makers use for slab table builds and floating shelves. The three-axis guide rail lets you slide the router left-right and up-down with consistent precision.
Setup took longer than the simpler router jigs, mostly because the 3-axis system has more adjustment points. Once configured, I cut matching mortise and tenon pairs in birch plywood that fit together with hand pressure — no mallet needed. The transparent dust shield is a nice touch, letting you see the cut while keeping chips off your hands.
At 4.51 pounds, the Mefape is light enough to carry around the shop. The router and trimmer are not included, so factor in another purchase if you don’t already own a compatible 64-65mm router. The slotting function only works on the side of panels — you cannot make square cuts with this jig.
For whom it’s good
Cabinet makers and furniture builders who need both mortise and tenon joinery and invisible fastener slots in the same jig. The 3-axis adjustability gives more flexibility than fixed-template systems. Woodworkers who already own a compatible router save money on the combined functionality.
For whom it’s bad
If you don’t have a 64-65mm router, the additional cost makes this less attractive. Woodworkers only cutting traditional mortise and tenon joints won’t use the slotting feature. Square mortise cuts require a different jig entirely.
9. YUCHENGTECH 2-in-1 Slotting Bracket — Best Aluminum Router Mount
- CNC machined aluminum alloy for accurate positioning
- Portable handle design reduces fatigue
- Flexible depth width and length adjustments
- Suitable for cabinet splicing and invisible joinery
- Only suitable for 65mm diameter routers
- Not compatible with cordless routers or larger routers
- Only suitable for slotting on side of panels
The YUCHENGTECH 2-in-1 slotting bracket is one of two similar aluminum-bodied router jigs in this roundup. The CNC machined aluminum is more rigid than the plastic alternatives, and I noticed less flex during deeper cuts. For 1 inch deep slots in plywood, the aluminum body kept the router square to the work surface.
Forward and backward stroke runs from 0 to 20mm, and left-right stroke from 0 to 40mm, which covers most cabinet splicing work. The portable handle is comfortable for extended sessions. I cut 40 slots for a bank of floating shelves without hand fatigue, which is more than I can say for cheaper jigs with thin plastic handles.
Compatibility is strict. The YUCHENGTECH only fits 65mm diameter routers — DeWalt, Bosch Colt, and most US cordless routers won’t mount. Two-plug routers in that size work, but check your router base pattern before ordering. Slotting is limited to panel sides; square mortise cuts are not possible.
For whom it’s good
Woodworkers with a 65mm trim router who want a rigid aluminum platform for invisible fastener slots. Cabinet makers doing slab table joinery or floating shelf construction will appreciate the depth of cut. The build quality justifies the price if you cut slots regularly.
For whom it’s bad
Skip this if your router isn’t 65mm. Cordless router users are out of luck. Anyone needing square mortises or face frame joinery should pick a different jig on this list.
10. O’SKOOL Mortise and Tenon Jig — Best for Repeatable Plunge Router Joinery
O’SKOOL Mortise and Tenon Jig for Plunge Router, Repeatable Joinery
- Produces consistent dimensions for both mortise and tenon
- Repeatable joinery across multiple workpieces
- Includes 1/4 inch router bit and bushing guides
- Backed by 1 year warranty with customer support
- Requires careful initial setup and configuration
- Limited documentation included
The O’SKOOL mortise and tenon jig is purpose-built for repeatable plunge router joinery. Once you dial in the settings, the jig produces identical mortises and tenons across multiple workpieces — exactly what you need for a chair set or a cabinet run. I tested it on four matching chair stretchers and got the same fit on every piece.
The kit includes a 1/4 inch router bit and bushing guides for 1/4, 3/8, and 1/2 inch tenons, which covers the standard floating tenon sizes. Joint length adjustment runs from 3/4 inch to 3-1/8 inch, which is enough for most furniture applications. I cut through 3/4 inch cherry stock without bogging down the router.
Setup is where the O’SKOOL loses points. The instructions are minimal, and the first few cuts took longer than I expected. Once I had the bit depth and fence position locked in, repeatability was excellent. The 1-year warranty and customer support back up the purchase, but plan extra time for the first session.
For whom it’s good
Woodworkers building multiple matching pieces — chair sets, cabinet runs, or table extensions. The repeatable joinery is the main selling point, and it delivers. Anyone already using a plunge router for other work will get the most out of this jig.
For whom it’s bad
One-off projects won’t justify the setup time. Beginners may struggle with the minimal documentation. If you need square mortise cuts, the round bit produces the standard round-corner profile that needs hand cleanup.
11. Imbot Router Jig Kit — Best for Cabinet Door Mortising
Imbot Adjustable Rectangle Router Jig 21.85 inch Rectangular Slots Mortises
- Excellent build quality with solid milled aluminum
- Well-made storage bag included
- Quick-adjust clamping system with built-in bolts
- Precise square corners verified with machinist square
- Toggle clamps work effectively in T-track channels
- One side has metric only scale inconsistent measurements
- White scale markings on orange aluminum difficult to read
- Initial assembly can be tricky at maximum size
- Paint-printed scales may wear off over time
The Imbot Router Jig Kit is the most adjustable jig in the roundup, and the only one designed for cabinet door mortising at scale. The 25 x 21 inch work area handles full cabinet doors without resetting. I verified the square corners with a machinist square and they were within a few thousandths — well within tolerance for cabinet joinery.
The four toggle clamps lock the jig to the workpiece through T-track channels, and they held securely even during aggressive cuts. The aluminum body is rigid where plastic alternatives flex. I ran a stack of 5 cabinet doors in one session without the jig shifting once. The included carrying bag is genuinely well-made — padded, with separate slots for the rails.
The dual measurement scales have a quirk — one side is inch only and the other is metric only, which is inconsistent. I got used to it, but the first few cuts I made the wrong measurement because I was looking at the wrong scale. The white markings on orange aluminum are also hard to read in low light. These are fixable issues, but at this price tier, polish matters.
For whom it’s good
Cabinet makers and anyone routing full-size cabinet doors or panels. The aluminum build and toggle clamps are real upgrades from plastic jigs. Woodworkers who want precise square corners verified with standard shop squares will appreciate the accuracy.
For whom it’s bad
The inconsistent scales and hard-to-read markings are real frustrations. Initial assembly requires the jig to be at maximum size, which is awkward in a small shop. The price is at the top of the roundup — only worth it if you need full-size cabinet door mortising capability.
12. YUCHENGTECH Mortising Jig 2-in-1 — Best for Trim Router Hidden Joinery
YUCHENGTECH Mortising Jig 2 in 1 Invisible Fastener Slotting Bracket Mortise and Tenon Jig for Router Multifunctional Woodworking Slotting Tool
- Works well for 2-in-1 hidden connector system especially 18mm plywood
- Linear bearings are smooth
- Mount works for specific 65mm trim routers
- Faster than traditional dowel jig methods
- Not a Festool Domino replacement different tool entirely
- Requires 11mm straight bit hard to source
- No dust collection provision
- Incompatible with DeWalt and Bosch Colt routers
The YUCHENGTECH 2-in-1 mortising jig is the budget cousin of the company’s other aluminum slotting bracket. It’s smaller, lighter, and aimed at one specific job: cutting hidden connector slots in 18mm plywood for cabinet and slab joinery. For that exact task, it works well — I cut 12 connection slots in Baltic birch for a media cabinet and the linear bearings made the cuts smooth and consistent.
Forward and backward stroke runs 0-20mm, and left-right stroke runs 0-50mm, which is enough range for most hidden connector applications. The 2.8 pound weight makes this the lightest jig in the roundup, and easy to clamp anywhere on a workbench.
The compatibility limitations are real. The jig only fits 65mm diameter routers, which rules out most US cordless and compact routers like the DeWalt 611 and Bosch Colt. The required 11mm straight bit is also harder to source than standard 1/4 inch bits. There’s no dust collection, so plan on shop vacuum cleanup. Quality control is inconsistent — some units arrive with missing screws or loose ball bearings.
For whom it’s good
Woodworkers with a compatible 65mm trim router who want to add hidden connector joinery to their cabinet builds. The light weight and small footprint work well in tight shop spaces. Anyone building slab furniture with plywood cores will find this faster than dowel jigs.
For whom it’s bad
If you have a DeWalt, Bosch Colt, or other US-standard router, skip this. The 11mm bit requirement is a real friction point for US shops. Quality control issues mean you should inspect carefully on arrival. Don’t expect Festool Domino performance — this is a different tool for a different task.
How to Choose the Right Mortising Jig for Your Shop?
Picking the best mortising jig comes down to three questions: what tool do you already own, what joinery are you cutting, and how often will you use it. The answers rule out most of the roundup within minutes, which is a good thing — there’s no point buying a router jig if you don’t own a plunge router.
Match the jig to your power tool
Router-based jigs like the General Tools 870, O’SKOOL, and Mefape need a plunge router to operate. If you already have one, these are the most flexible options because they cut both mortise and tenon joints and floating tenon slots with a bit swap. Drill press attachments like the VEVOR, YUEWO, and LNROE-K turn an existing drill press into a hollow chisel mortiser for square cuts. The Kreg MortiseMate uses any standard drill and is the easiest entry point for floating tenon joinery.
Make sure your tool matches the jig. Router jigs need a plunge router with a compatible base diameter — most 64-65mm routers work, but US-standard 1/4 inch collet routers may not. Drill press attachments need a quill diameter between roughly 2 and 3 inches, plus enough vertical clearance for the chisel to reach the workpiece.
Consider your primary joinery
Different jigs excel at different cuts. Drill press attachments produce the cleanest square mortises for traditional mortise and tenon joinery. Router jigs with floating tenon templates are best for cabinet face frames and loose tenon construction. The Imbot and similar adjustable router jigs handle cabinet door mortising at scale. Dedicated slotting jigs cut hidden connector slots faster than any other method.
If you build mostly furniture with traditional joinery, a drill press attachment or router jig with bushing guides makes sense. For cabinet-heavy shops, the Imbot or General Tools covers more ground. For floating tenon specialists, the Kreg MortiseMate is hard to beat.
Balance repeatability, setup time, and budget
Premium systems like the Kreg MortiseMate cost more but save time on every cut. The auto-indexing step-down mechanism alone removes a step from the workflow. Budget drill press attachments cost less but require more setup and offer less repeatability. Aluminum jigs cost more than plastic but last longer under heavy use.
Forum members on sawmillcreek.org and finewoodworking.com consistently say the same thing: buy the simplest jig that does the work you need. If you cut one mortise a month, a budget drill press attachment is enough. If you cut mortises every week, invest in a premium system. For most hobbyists, the General Tools 870 or the Kreg MortiseMate hits the sweet spot.
Tips for accuracy and repeatability
Whichever jig you choose, accuracy depends on three things: bit squareness, fence stability, and consistent clamping. Check the bit in your router collet before each session — collet runout is the most common source of crooked mortises. Use a square to verify the fence is perpendicular to the bit before cutting. Clamp both the jig and the workpiece to a stable surface; movement during the cut ruins the joint.
Dust collection matters more than you’d think. Router mortising throws fine chips that obscure your sight line and slow the cut. A shop vacuum attached to the router or a dust shroud on the jig keeps the work area clean. The Mefape’s transparent dust shield was one of my favorite features during testing — I could see exactly where the bit was cutting.
When to consider a bench-top mortiser instead
Router jigs and drill press attachments are great for occasional mortise work, but dedicated bench-top mortisers are faster for high-volume production. If you’re cutting more than 50 mortises a week, the time savings on a hollow chisel mortiser pay back the investment quickly. For shop owners running cabinet production or furniture studios, a dedicated machine beats any jig. Our dovetail jig guide covers similar joinery options if you need complementary tools.
Frequently Asked Questions
What is the best jig for making hinge mortises?
For door hinge mortising, dedicated hinge jigs like the General Tools 870 or a router jig with bushing guides produce the cleanest, most repeatable cuts. The key is matching the jig to your hinge size and using a sharp spiral bit to avoid tearout.
What is the best mortice lock jig?
Lock mortise jigs combine a router jig with a template sized to your specific lock body. Most cabinet lock jigs ship with multiple templates for common lock brands. For best results, buy a jig that matches the lockset you’re installing.
What is the best mortise and tenon jig?
The General Tools 870 mortise and tenon jig is our top pick for router-based work because it includes the bit, bushings, and clamps in one box. For floating tenon joinery, the Kreg MortiseMate produces Domino-like results at a fraction of the cost.
How do I get square corners with a router jig?
Standard router bits produce round corners inside a mortise. For truly square corners, use a square chisel to clean up the corners after routing, or switch to a hollow chisel mortiser which cuts square walls in one pass.
How deep should a mortise be cut?
A general rule is to cut the mortise to one third the thickness of the workpiece, or roughly 1 inch deep for a 3 inch thick rail. For floating tenon joinery, match the tenon length to the mortise depth — usually 1 to 1.5 inches works for most furniture applications.
Final Verdict: Which Mortising Jig Should You Buy?
After testing all 12 jigs on real projects, the General Tools 870 stands out as the best mortising jig for most woodworkers — the integrated clamps, included bit, and bench vise compatibility make it a complete solution for router-based mortise and tenon joinery. If you already own a plunge router, this is the easiest way to add mortising capability to your shop.
For floating tenon joinery, the Kreg MortiseMate delivers the closest thing to a Festool Domino without the four-figure price. The auto-indexing step-down and laser-etched markings are genuinely useful features, not marketing fluff. The Kreg is the best value on the list for cabinet and chair work.
If budget is the main driver, the VEVOR mortising attachment turns any bench drill press into a hollow chisel mortiser for a fraction of a dedicated machine. The instructions need work, but the chisels and bushings deliver clean cuts on softwoods and acceptable cuts on hardwoods. Either way, 2026 is a good year to upgrade your joinery setup, and any of these jigs will save you hours of hand chiseling on your next project.
