Kreg MortiseMate Loose Tenon Jig

Regular price $299.90

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.
