Description
Compression spirals designed for making mortise cuts or cutting 5/8" or thinner material. Designed with a 1/4" upcut or less preventing chipping or fuzzing on the top and bottom of the material being cut. "Mortise Cuts" are grooves cut in the material usually at a depth equal to or slighty less than the diameter of the tool. By using both left and right rotations, users can climb cut in either direction and control "blow out" on entrance and exit cuts of material.
