Tooth design - A variable 4-6 teeth per inch tooth design with a positive 10 degree tooth angle provides the following benefits: Faster and more aggressive cut. Improved heat dispersion during cutting ensures that the teeth stay sharper for longer. Deeper curved gullets provide more efficient chip clearance preventing clogging and heat build-up. Special shaped tooth angle has less tendency to snag on thinner materials. Teeth are alternate side set to minimise binding and friction. Requires less feed pressure. This is achieved by the combination of aggressive tooth geometry and good chip clearance resulting in the requirement of less force during drilling.
