Product Information

A smooth result is also achieved via the teeth, which have a constant pitch at 8tpi, meaning there are more teeth actually cutting at a constant rate. Additionally manufactured to a high standard from 8% cobalt alloy steel, giving vastly superior performance than normal HSS materials - the slim line design reduces frictional heat build-up and prevents tooth burn out.
