Value Collection C1100709 Woodruff Keyseat Cutter Hss

Product Description

The VALUE COLLECTION C1100709 is a Woodruff keyseat cutter designed for milling the curved keyway seats that accept Woodruff keys in shafts and hubs. Built from high-speed steel (HSS) with a bright, uncoated finish, this cutter delivers reliable performance in manual and CNC milling operations. It features a 1.125-inch cut diameter, a 0.2188-inch (7/32 inch) cutting width, and 12 straight teeth arranged for consistent chip removal. The 1/2-inch shank mounts directly into standard milling machine collets or end mill holders. This cutter conforms to ANSI Standard Number 709 and Old Standard Number 17, making it a recognized size in the Woodruff keyseat system.

This cutter is used in machine shops, maintenance facilities, and manufacturing environments where Woodruff keyways must be cut into shafts, spindles, or bores. It is appropriate for both production and repair work on ferrous and non-ferrous materials. Machinists and tool-and-die professionals select this cutter when working to ANSI Woodruff key seat specifications on light to medium-duty milling equipment. The straight-tooth configuration is well suited to conventional milling setups without the need for spiral or staggered geometry.

• 2.2188-inch overall length provides adequate reach for typical keyseat depth requirements

Compatibility

Designed as a direct-fit Woodruff keyseat cutter conforming to ANSI Standard Number 709 (Old Standard Number 17), compatible with 1/2-inch collets and end mill holders on standard vertical and horizontal milling machines.

Installation Notes

This cutter should be installed and operated by qualified machinists familiar with milling machine setup and cutter safety practices. Secure the shank fully in the collet or holder and confirm runout before cutting. Power down and lock out the machine before changing or inspecting the cutter. Do not exceed the feed and speed parameters appropriate for the workpiece material and machine rigidity.
