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.
Infinity has now made this system complete, with our new MortiseMate Master Pack. We have bundled the core tool, all of the cutters and a pack of each size of loose tenons in one convenient package. You can maximize your joinery options with one easy step.

Wow, I never thought that I would be able to afford loose tenon joinery, but Kreg has scored with this unit! The slot width is easily adjustable from snug to loose fitting. I found that the carriage retracts easily by pushing down on the center button, something not mentioned in the user's guide. I highly recommend this quality accessory!
