Description
Drill Square Holes in Wood Using Your Drill Press
Our mortise chisel bits are specially designed to cut clean, square holes in wood using either a dedicated mortising machine or a drill press fitted with a mortising attachment. The inner twist drill removes material, while the outer square chisel slices the corners clean — making them ideal for mortise and tenon joinery.
Crafted from high carbon steel and chrome plated for durability and smooth cutting, they’re perfect for both hardwood and softwood applications.
