The Kreg® MortiseMate™ Loose Tenon Jig revolutionizes traditional wood joinery, making it easier than ever to create precise, hidden loose tenon joints. Designed to combine the accuracy of a router with the simplicity of a drill, this innovative tool features an auto-indexing step-down mechanism, micro adjustment screws, and an integrated mini work surface—allowing you to produce professional-quality joints with just a drill, no router required.

The MortiseMate's unique auto-indexing step-down mechanism ensures consistent, precise mortise cuts. As you work, the cutter automatically steps down by 1/16" with each pass, ensuring flawless joints every time, without the need for complex setups.

Achieve a perfect fit for your loose tenons with the micro adjustment screws, which allow you to fine-tune the mortise width for tighter or looser fits, depending on your project needs.

The built-in mini work surface makes clamping your workpiece quick and easy, whether you're working with trigger clamps for a permanent setup or need to move the jig around for a more portable solution.

Ideal for high-precision woodworking, the MortiseMate simplifies projects that require strong, accurate joints, saving you time while delivering superior results.

Brian ★★★★★

Swapped out my router setup for this jig and the difference is night and day—the template guides keep the tenons dead-on every pass, no more fiddling with bit depth. Cut a dozen joints for a coffee table in under an hour, and they all fit snug as a glove.

Victoria ★★★★★

I was able to cut perfectly centered mortises on my first try without any tear-out—the indexing pins made alignment dead simple. The whole setup feels solid and precision-machined, not like a cheap plastic jig.

Mia ★★★★★

The clamping mechanism locks the workpiece down rock-solid, which made my first set of test mortises come out perfectly centered. I was able to set up and make a complete joint in under five minutes.
