Value Collection C22001208 Woodruff Keyseat Cutter Cobalt

Product Description

The VALUE COLLECTION C22001208 is a Woodruff keyseat cutter designed for milling semicircular keyseats into shafts and mating components. Built from M42 cobalt high-speed steel with a bright, uncoated finish, it delivers good wear resistance in ferrous and harder workpiece materials. The cutter measures 1 inch in cut diameter with a 0.375-inch cutting width and a 1/2-inch shank diameter, yielding an overall length of 2.375 inches. Ten staggered teeth reduce chatter and improve chip evacuation during the cut. This tool is intended for machinists, toolroom operators, and maintenance technicians working on shaft-and-key assemblies.

This cutter is suited for use on manual knee mills, CNC vertical machining centers, and tool-and-cutter grinder setups where precise keyseat geometry is required. It conforms to ANSI standard number 1208 (Old Standard 152), making it a recognized size for standard Woodruff key applications in general industrial, automotive, and mechanical maintenance environments. It is appropriate for both production runs and one-off repair work where accurate keyseat depth and width are critical to proper key fit and torque transfer.

Key Features

• M42 cobalt construction for improved hardness and heat resistance compared to standard M2 HSS
• Staggered tooth configuration reduces cutting forces and minimizes chatter
• Bright uncoated finish suitable for a wide range of cutting fluid applications
• Conforms to ANSI 1208 and Old Standard 152 for standardized keyseat sizing
• 10-tooth count balances chip load per tooth with smooth surface finish
• 1/2-inch straight shank for direct mounting in standard milling collets or arbors

Compatibility

Designed as a standard ANSI 1208 Woodruff keyseat cutter for use wherever an ANSI 1208 or Old Standard 152 keyseat profile is specified on shaft assemblies.

Installation Notes

Installation is performed by qualified machinists using a collet, end mill holder, or keyseat arbor rated for the 1/2-inch shank diameter. Secure the workpiece firmly in a vise or fixture and confirm machine spindle runout is within tolerance before engaging the cut. Use appropriate cutting fluid for the workpiece material and never exceed the cutter manufacturer's recommended feed and speed parameters for cobalt HSS tooling. Inspect the shank and collet bore for chips or damage before mounting.
