The Omega M7 line of end mills from Imco Carbide Tool is designed for machining hardened steels ranging to 58 to 62 HRc, running wet or dry. The end mill range features updated corner geometries, a 50-degree helix angle, and cutting edges with an enhanced AlTiNX coating to protect from heat generated in the cutting zone, even under extreme cutting conditions. The aggressive, high-performance end mills are said to reliably produce quality surface finishes.
The Omega M7 line is available in sizes ranging from 1/8" to 3/4" in a variety of lengths, with neck relief and corner radii as standard options. The M725 tools (sizes 1/8" to 3/16") have five flutes, while the M726 tools (sizes 1/4" to 3/4") have six flutes for more cutting edge engagement per rotation, higher ipm in hardened steels and increased tool life.
