5/16" OD x 1" Shank OD x 1-1/2" LOC x 4" OAL 4-Flute Single End High-Speed Steel (HSS) Tapered End Mill, 30° Helix, Center Cut, 25° Taper, Bright Finish (Uncoated).
This 4-flute high-speed steel (hss) tapered end mill uses a 30° helix and 25° taper for controlled milling of angled walls, tapered slots, pockets, molds, dies, and contoured features. The center-cutting geometry supports controlled axial entry, ramping, and pocketing when appropriate for the workpiece and setup.
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 bright, uncoated finish provides a direct cutting edge for tapered milling where an added coating is not required.
