Style 294 (TiN) / 294A (TiAlN), Solid Carbide, Kooltwist? High Performance, Short Length Drill. Submicron carbide grade provides maximum wear resistance when cutting steels, stainless steels, titanium, high temperature alloys, aluminum, bronze, cast and ductile iron. Coating adds lubricity, enhances wear resistance and prevents edge build-up. TiN coating is recommended for long chipping, low-carbon, ductile and gummy materials. TiAIN coating is recommended for short chipping, abrasive and high temperature materials. Coolant feeding solid carbide Kooltwist? high performance drills yield higher penetration compared to non-coolant fed high performance drills when drilling deep holes.
