High Speed Steel Annular Cutters with a drill depth of 30 mm feature unique teeth geometry, provide clear cutting, fast feed rate, less vibration, smooth hole surface and long tool life. These HSS annular cutters – 30 mm 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. The rest material created with the use of these annular cutters is the signature Euroboor slug. The rim on this slug is exactly what prevents our HSS annular cutters – 30 mm from penetrating the second layer of material.
