The Kreg MortiseMate™ Loose Tenon Jig provides a straightforward way to produce accurate, repeatable loose tenon joints using only a drill. Designed to deliver the control and consistency usually associated with router‑based systems, it allows clean mortises to be cut without complex setup. Suitable for workpieces from 12.5mm to 38mm thick, it’s well suited to furniture making, cabinetry and frame construction where strong, concealed joints are required.
At the core of the system is an auto‑indexing step‑down mechanism that automatically lowers the cutter by 1/16″ with each pass, giving precise control over mortise depth. Using the supplied 6mm cutter, mortises can be cut up to 3/4″ deep, while optional 8mm and 10mm cutters increase the maximum cutting depth to 1″. Micro‑adjustment screws allow the mortise width to be fine‑tuned, making it easy to achieve the desired fit for different tenon sizes. Clear, laser‑etched markings on both the jig and cutter support accurate setup and repeatable results.
An integrated mini work surface allows fast, secure clamping with trigger‑style clamps, making the MortiseMate equally suitable for fixed workshop use or portable setups. Supplied with a carbide‑tipped 6mm mortising cutter, the system can be expanded with additional cutter sizes as needed. Constructed from stainless steel and precision‑machined anodised aluminium, the jig is built for durability and long‑term accuracy, offering an efficient and accessible approach to modern loose tenon joinery.
Supplied as a complete, ready‑to‑use system, including a carbide‑tipped 6mm MortiseMate mortising cutter fitted with a stop collar, an integrated mini work surface and a dust‑collection adapter suitable for 1¼″ vacuum hoses. A set of hex wrenches is included for setup and adjustment, along with a full owner’s manual to guide installation and use.
The jig is covered by a three‑year limited warranty for added peace of mind.
