HEPYC Series 31191 – 18.0mm HSS-Co TiAlN Roughing End Mill

The HEPYC Series 31191 Roughing End Mill is a high-performance milling cutter designed for aggressive material removal and reliable machining in demanding applications. Manufactured from cobalt-alloyed high-speed steel (HSS-Co) and finished with a durable TiAlN coating, this tool delivers excellent wear resistance, heat stability, and extended tool life.

Featuring a DIN 844 NRF geometry with 4 serrated flutes, this roughing end mill reduces cutting forces, improves chip evacuation, and allows for higher feed rates compared to conventional end mills. It is ideal for roughing operations in steel, stainless steel, cast iron, and high-strength alloys.
