1-1/8" Cutter OD x 1/2" Shank OD x 5/16" Radius x 3-1/4" OAL 3-Flute Single End High-Speed Steel Corner Rounding Cutter, Bright Finish (Uncoated).
This 3-flute single-end HSS corner rounding cutter is designed to machine a consistent 5/16" external corner radius on part edges. Its profiled cutting geometry supports controlled edge blending, deburring, and radius generation on shoulders, plates, slots, and contoured workpieces.
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 HSS cutting edge for general-purpose corner rounding where an added coating is not required.
