Value Collection C2100203 Woodruff Keyseat Cutter Cobalt

Product Description

The VALUE COLLECTION C2100203 is a Woodruff keyseat cutter designed for milling semicircular keyseats into shafts and mating components. Built from M42 cobalt high-speed steel, it delivers reliable performance in harder workpiece materials where standard HSS tooling loses its edge. The cutter measures 0.375 inches in cut diameter with a 0.0625 inch (1/16 inch) cut width, and mounts via a 1/2 inch shank for secure spindle engagement. With 6 straight teeth and a bright uncoated finish, it is suited for conventional milling operations on manual or CNC knee mills and milling machines. Machinists and tool-and-die professionals specify this type of cutter for Woodruff key slot production to ANSI standard 203.

This cutter is used in general metalworking, tool-and-die, and machine shop environments where Woodruff keyseats are required on shafts, spindles, and mechanical drive components. The straight tooth configuration is appropriate for standard keyseat applications in ferrous and non-ferrous metals. Its compact 2-1/16 inch overall length makes it practical for use in tight setups and on smaller milling machines. This cutter is sold individually and is a direct fit for shops needing ANSI 203 or Old Standard 211 equivalent tooling.

Key Features

• M42 cobalt construction for extended tool life in harder materials
• Straight tooth configuration for standard keyseat milling operations
• 0.375 inch cut diameter with 0.0625 inch cut width for precise Woodruff slot profiles
• 1/2 inch shank diameter for common milling machine spindle compatibility
• Bright uncoated finish suitable for use with standard cutting fluids
• Conforms to ANSI standard 203 and Old Standard 211

Compatibility

Conforms to ANSI American Standard Number 203 and Old Standard Number 211. Designed as a direct replacement or equivalent for Woodruff keyseat cutter applications requiring ANSI 203 specification tooling with a 1/2 inch shank.

Installation Notes

This cutter is installed by a machinist into a milling machine spindle using a standard arbor or collet chuck rated for the 1/2 inch shank diameter. Ensure the spindle is fully stopped and locked before mounting or removing the cutter. Use appropriate cutting fluid for the workpiece material to maintain edge life and surface finish. Secure workholding is critical when milling keyseats to prevent movement and tool breakage.
