Mortise & Tenon Joinery

A well-fitted mortise-and-tenon joint cut with sharp tooling and accurate layout is one of the strongest joints in woodworking when glued with appropriate adhesive. Consistent wall thickness, flat bottoms, and square shoulders are the key dimensional requirements for a tight, strong joint.

Yes. A plunge router with a spiral upcut bit or a dedicated mortise-and-tenon router bit—such as the Infinity Tools 1/2" Shank Mortise-Tenon Router Bits—cuts clean, flat-bottomed mortises quickly and accurately. A router dado jig guides repeatable mortise placement.

A 1/2" shank provides greater rigidity and reduces vibration during heavy mortising cuts in hardwood. A 1/4" shank bit is suitable for lighter-duty routers and portable trim applications. For full-size mortise-and-tenon work in hardwood, 1/2" shank bits are the preferred choice.

Mortise-and-tenon layout requires a mortise gauge to scribe the joint width, a marking knife for shoulder lines, and a square to transfer lines around the workpiece. The iGaging Ebony Mortise Gauge and Wheel Marking Mortise Depth Gauge cover both aspects of layout.

The Milescraft Door Mortise Kit is a router template system sized to standard door hinge leaf dimensions. It guides the router to cut precise hinge recesses in both the door edge and door jamb, ensuring a flush hinge installation without measuring each mortise individually.

Yes. A stacked dado set is one of the most efficient ways to cut tenon cheeks on the table saw. The Infinity Tools Pro Grip Master Dado Set cuts flat-bottomed dados and rabbets, making it well-suited for removing tenon cheek material in multiple consistent passes.

Yes. The Kreg MortiseMate system creates floating loose-tenon joints by routing matching mortises in both workpieces and inserting a pre-made tenon. This approach produces a strong, glue-ready joint without the need to cut a tenon on the workpiece itself.

Mortise-and-tenon joints are stronger and more durable for load-bearing applications like chair legs and table bases. Pocket-hole joinery is faster and suitable for face frames, cabinet boxes, and furniture where glue surface and joint geometry differ. Both have a place in a well-equipped shop.
