Review on ✂️ High-Performance CMT 191 506 11 Carbide Spiral Diameter: Enhanced Precision for Optimal Cutting Results by Kevin Mitchell

This cutter is very sharp. I use it to cut a 1/2" x 1/2" dado out of maple to make Japanese lampshades. The cuts are very clean with no chips and the tabs are very smooth in the grooves. Great care must be taken not to drop the drill bit on the concrete as the tip is brittle and can break off if struck against hard surfaces.
