1/4" Dia, 3-1/4" OAL, End Mill 4-Flute SE CC 25° TAPER HSS TiCN, T25-D-4CN
Premium USA made 4 Flute HSS Single End Regular Length Tapered End Mill. High Speed Steel (HSS) provides good wear resistance and costs less than cobalt or carbide end mills. HSS is commonly used for general purpose milling applications. This end mill has a Center Cutting end cut and is TiCN coated. TiCN (Titanium Carbonitride) coating has up to 750 Degree F thermal stability. TiCN offers imporved wear resistance to abrasive, adhesive, or difficult to machine materials such as cast iron, aluminum alloys, tool steels, copper, inconel and titanium alloys. TiCN is harder and more impact resistant than TiN due to its low thermal stability, it is recommended to be used in sufficiently cooled and fabricated cuts.
