ISCAR’S Sumocham 12xD depth to diameter ratio DCN drills feature cylindrical shanks, which enable clamping the drill on hydraulic toolholders or in spring collets. All drill bodies feature helical coolant holes. Before using the 12xD drill, it is recommended to drill a pre-hole by using a DCN 1.5xD drill or a center drill.
