ISE Square End Mill - 4 Flutes

█Features: ①HIGH PERFORMANCE FOR HARD MATERIALS - Cutter is made of Micro Grain Carbide that is very tough, resists wear and offers high cutting performance. ②AlTiBN COATING - Titanium aluminum boron nitride (AlTiBN) coating lubricates the end mill for stability at high temperature and superior wear resistance at high cutting speeds, offering better heat resistance than TiAlN, TiN or TiCN coatings. ③ HIGH-QUALITY - Flutes ground by a world-class ISO-9001 Factory; Great performance at a competitive price. █Application: GENERAL APPLICATION CUTTER - Speed Tiger 600 Nano carbide tools excel at working carbon steels (~HB225), alloy steels (HB225~325), pre-hardened steels (up to HRC45), hardened Steels (HRC40~45), cast iron.
