High Speed Steel Annular Cutters 2″ with a drill depth of 2″ feature unique teeth geometry, provide clear cutting, fast feed rate, less vibration, smooth hole surface and long tool life. These HSS annular cutters – 2″ can be widely used in drilling steel, copper, aluminum, stainless steel and plastic, in either plate or pipe form. HSS Euroboor annular cutters feature teeth geometry which is optimized for use on single layer metal work pieces, ensuring the fastest and best drill performance.
