Value Collection C2100609 Woodruff Keyseat Cutter Cobalt

Product Description

The VALUE COLLECTION C2100609 is a Woodruff keyseat cutter designed for cutting keyseats in shafts and hubs to precise dimensional tolerances. Built from M42 cobalt high-speed steel with a bright, uncoated finish, it delivers hardness and heat resistance suited to production and toolroom environments. The cutter features a 1.125-inch cut diameter, a 0.1875-inch cutting width, and a 1/2-inch shank diameter, with an overall length of 2.1875 inches. Twelve straight teeth provide clean, consistent cuts. This tool meets ANSI Standard 609 (Old Standard No. 16) and is suited for machinists and tool-and-die professionals working with standard Woodruff key applications.

This keyseat cutter is used in general metalworking and machining operations where Woodruff keyseats must be milled into round stock. It fits standard milling machines and CNC machining centers equipped with a compatible 1/2-inch tool holder or arbor. Typical applications include shaft keyway preparation in manufacturing, repair, and maintenance settings across industrial, automotive, and mechanical service environments. The straight-tooth configuration is well suited to conventional milling cuts in steel and similar materials.

Installation Notes

Installation and use should be performed by qualified machinists familiar with milling operations. Secure the shank firmly in a compatible 1/2-inch tool holder or arbor before use, and ensure the spindle is fully stopped before changing tooling. Always verify workpiece clamping and machine guarding are in place before initiating a cut. Follow applicable shop safety standards and manufacturer feeds-and-speeds recommendations for cobalt tooling in the material being machined.
