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.

Again, I was looking for a good quality resaw blade that left a good surface and that retained it's sharpness for a long time. So far, the blade I'm using is fulfilling both. Just remember to check the silica content on the wood you're resawing. Purpleheart and Koa will kill any blade real fast.
