9/16" Cutter OD x 1/2" Shank OD x 15/64" Width of Cut x 2-19/32" OAL 8-Flute Single End High-Speed Steel T-Slot Cutter, 30° Helix, Non-Center Cut, 1/4" Bolt Size, Bright Finish (Uncoated).
This 8-flute high-speed steel T-slot cutter is designed for machining bolt T-slots with a 1/4" nominal bolt size after the required entry slot has been produced. The 30° helix supports controlled chip flow, while the non-center-cutting geometry is intended for lateral engagement.
High-speed steel provides toughness and resistance to chipping for slotting, maintenance, and production applications that benefit from a more forgiving cutting edge than carbide.
The bright, uncoated finish provides a direct HSS cutting edge for general-purpose T-slot and bolt-slot milling applications where an added coating is not required.
