Value Collection C2100810 Woodruff Keyseat Cutter Cobalt

Product Description

The VALUE COLLECTION C2100810 is a Woodruff keyseat cutter designed for milling Woodruff keyseats in shafts and other machined components. Built from M42 cobalt high-speed steel with a bright, uncoated finish, it delivers solid wear resistance in ferrous and harder workpiece materials. The cutter measures 1.25 inches in cutting diameter with a 0.25 inch cutting width, rides on a 0.5 inch shank, and carries 14 straight teeth for clean, consistent cuts. Overall length is 2.25 inches. It conforms to ANSI Standard 810 (Old Standard 21), making it a direct fit for standard Woodruff keyseat applications. Machinists and toolroom technicians use this cutter on manual mills and CNC machining centers.

This cutter is suited for production and maintenance environments where standard Woodruff key slots are required in shafts, spindles, and other precision components. The straight-tooth configuration is appropriate for conventional milling in steel, cast iron, and similar materials. It is packaged and sold individually, making it practical for toolroom replenishment or low-volume keyseating work. The ANSI 810 designation ensures dimensional interchangeability with other standard Woodruff keyseat tooling of the same number.

Key Features

• M42 cobalt high-speed steel construction for extended tool life in harder materials
• 14 straight teeth for consistent keyseat geometry and clean side walls
• 1.25 inch cutting diameter and 0.25 inch cutting width per ANSI 810 standard
• 0.5 inch shank diameter for compatibility with standard milling arbors and collets
• Bright, uncoated finish — ready to use as delivered
• Conforms to ANSI Standard 810, Old Standard Number 21

Compatibility

Designed as a standard ANSI 810 Woodruff keyseat cutter for use on horizontal and vertical milling machines accepting a 0.5 inch shank arbor or collet. Dimensional compliance with ANSI 810 ensures interchangeability with other tooling of the same standard designation.

Installation Notes

Installation and use of this cutter should be performed by a qualified machinist familiar with milling machine setup and safe tooling practices. Ensure the machine spindle is fully stopped and the power is locked out before mounting or removing the cutter. Verify arbor or collet runout before beginning the cut, as excessive runout accelerates tooth wear and degrades keyseat geometry. Follow applicable shop safety standards and machine manufacturer guidelines for speeds and feeds appropriate to the workpiece material.
