Sharp technology with a new twist! This upcut spiral bit with chipbreaker is made of a special super-micrograin carbide formula which makes the cutting edges very sharp. The new low-angle spiral is designed to shear wood cleanly and provide excellent chip ejection. As a result, the tool will run cooler and the cutting edges will last longer The spiral bit produces an excellent finish on the lower side of your workpiece. Excellent cutting results and enhanced productivity. For fast routing on CNC equipment when the edge finish is less important.
