Value Collection C2100812 Woodruff Keyseat Cutter

Product Description

The VALUE COLLECTION C2100812 is a Woodruff keyseat cutter designed for milling semicircular keyseats into shafts and mating components. Built from M42 cobalt high-speed steel, it delivers heat and wear resistance suited to production cutting in tougher materials. The cutter measures 1.5 inches in diameter with a 0.25 inch cutting width and mounts on a 1/2 inch shank. With 16 straight teeth and a bright uncoated finish, it conforms to ANSI standard 812 (Old Standard No. 24). Overall length is 2.25 inches. Machinists and tool-and-die professionals use this style of cutter on milling machines to produce keyseat slots that accept Woodruff keys in shaft assemblies.

This cutter is suited for horizontal or vertical milling machine setups where Woodruff keyseat profiles are required on shafts, spindles, or similar cylindrical workpieces. Typical applications include general machining shops, maintenance and repair operations, and light manufacturing environments. The straight-tooth configuration provides clean entry and consistent chip clearance in a variety of ferrous and non-ferrous materials. It is sold individually and is appropriate wherever ANSI 812 keyseat geometry is specified.

Key Features

• M42 cobalt HSS construction for improved heat resistance and extended tool life in harder materials
• 16 straight teeth for consistent chip load and smooth keyseat finish
• Conforms to ANSI standard 812, Old Standard No. 24 — matches common engineering print callouts
• Bright uncoated finish — ready for use as supplied, no additional prep required
• 1/2 inch shank diameter for compatibility with standard milling machine arbors and collets
• Compact 2.25 inch overall length minimizes overhang and deflection during cut

Compatibility

Designed for use on horizontal and vertical milling machines accepting a 1/2 inch shank. Conforms to ANSI 812 Woodruff keyseat cutter geometry, making it a direct fit wherever that standard is specified on engineering drawings.

Installation Notes

Installation is performed by qualified machinists on properly maintained milling equipment. Secure the shank firmly in a collet or arbor before operation and verify runout before taking a cut. Power down and lock out the machine before mounting or removing the cutter. Do not exceed the machine manufacturer's recommended spindle speed for the cutter diameter and material being cut.
