Style 114 (TiN) / 114A (TiAlN), Solid Carbide, High Performance, Stub Length Drill. Submicron carbide grade provides maximum wear resistance when cutting high carbon, high alloy and stainless steels, titanium, high temperature alloys, aluminum, bronze, cast and ductile iron. Available in TiN or TiAIN coating. 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.
