Lock Mitre

Lock mitre cutters in single and double tongue-and-groove styles for self-aligning, glue-strong 45° case corners — counterclockwise rotation only.

With the double T&G cutter, part B runs flat on the shaper table and part A vertical against the fence; the single T&G three-cutter set handles material to 1-1/8" with both parts run flat, part B grooved afterward on the table saw. Mini-Pro sizes are made to run only on a 3/4" spindle.
