5/8" OD x 1/2" Shank OD x 1-3/8" LOC x 3-3/8" OAL 2-Flute Single End High-Speed Steel (HSS) Finishing End Mill, 37° Helix, Center Cut, Ball Nose, Regular Length, Aluminum-Cutting Geometry, TiAlN Hard Coat.
This 2-flute high-speed steel (hss) finishing end mill uses a 37° helix and regular length construction for accurate, controlled milling. The ball-nose profile is suited to contoured surfaces, fillets, molds, dies, and three-dimensional finishing passes. The center-cutting geometry also supports controlled axial entry, ramping, and pocketing when appropriate for the workpiece and setup. This tool is identified in the source specification as Aluminum-Cutting Geometry.
High-speed steel provides toughness and resistance to chipping for general machining, repair work, interrupted cuts, and setups that benefit from a forgiving cutting edge.
The TiAlN Hard Coat is intended for improved heat and wear resistance in demanding finishing applications.
