Looking for a compact jig that delivers big results? Whether creating edge, corner, or surface joints, the JointMaster™, is an adaptable jig that transforms to join any woodworking project. The all-metal construction means that the jig won’t bend or flex when joining boards; creating stronger and more consistent joints.

The JointMaster™ comes with three drill blocks and is capable of creating joints using the most common dowel pin sizes- 1/4″, 5/16” and 3/8”. Each hardened steel drill block is adjustable to accept and align centered dowel holes on boards from 1/2” up to 3”. Built-in scales help to align and center your dowels. The convenient centering marks make sure your holes are where you want them. If you’re using standard 1/2”, 5/8”, 3/4, or 1-1/2” boards, three included Spacer Blocks will automatically align the drill blocks and help you select the appropriate dowel size.

To help eliminate alignment issues, the JointMaster™ has built-in edge stops.  Simply lower, tighten, and rest your boards against them to ensure both boards have their dowel holes in the same position for a solid joint. When creating surface joints, the three dowel alignment slots help you transfer the edge dowel position to the face of your board with ease.

The self-clamping design of the JointMaster™ means no additional clamps are needed to complete your project.  The clamp can be moved from the main body to the clamping wall to create different joints. If required, the clamp body can be removed entirely based on your project needs and your own clamping solution can be used.

When you require professional quality joint work, make sure the Milescraft JointMaster™ is part of your tool arsenal.
