9/16" OD x 5/8" Shank OD x 1-3/8" LOC x 5" OAL 3-Flute Double End High-Speed Steel (HSS) Finishing End Mill, 30° Helix, Center Cut, Ball Nose, Regular Length, TiCN Premium Grade Coating.
This 3-flute high-speed steel (hss) finishing end mill uses a 30° 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. The standard finishing geometry is intended for controlled sizing and surface-finish passes.
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 TiCN Premium Grade coating provides a hard, low-friction surface intended to improve wear resistance in suitable milling applications.
