* Coolant feeding S.C. Kooltwist high performance drills yield higher penetration compared to non-coolant fed high performance drills when drilling deep holes. * 140° double split point provides excellent chip flow over the entire cutting edge. * Tool life is increased and peck drilling can be eliminated when used with high pressure coolant. * Larger sizes available see Style 292. * Coating adds lubricity, enhances wear resistance and prevents edge build-up. TiN coating is recommended for long chipping, low-carbon, ductile and gummy materials. TiAlN coating is recommended for short chipping, abrasive and high temperature materials. * Allow 1.5 x Ø of flute for chip exit up to 7/16†(11.1mm) and 1 x Ø over 7/16â€. * Some tool holders and stop screws with a single, central coolant hole may require a coolant groove be added to the shank end of the drill.
