Value Collection C2100605 Woodruff Keyseat Cutter Cobalt

Product Description

The VALUE COLLECTION C2100605 is a Woodruff keyseat cutter designed for milling semicircular keyseats into shafts and mating components. Built from M42 cobalt high-speed steel, it delivers enhanced heat and wear resistance compared to standard HSS tooling, making it suitable for harder workpiece materials and higher cutting speeds. The cutter measures 0.625 inches in diameter with a 0.1875 inch cutting width, mounts on a 1/2 inch shank, and carries 8 straight teeth in a bright, uncoated finish. It conforms to ANSI American Standard Number 605 and Old Standard Number 61. Machinists and toolroom technicians use this cutter on manual mills, knee mills, and CNC machining centers.

This cutter is applied in shaft keyway preparation across general machining, repair shops, and production environments where Woodruff key seats are required. The straight-tooth configuration suits conventional milling of keyways in steel, cast iron, aluminum, and similar materials. With an overall length of 2.1875 inches and a 1/2 inch straight shank, it fits standard milling collets and arbors used in both manual and CNC setups. Typical applications include drive shaft keyway cutting, fixture work, and toolroom repair operations.

Key Features

• M42 cobalt HSS construction for improved hot hardness and wear resistance over standard M2 HSS
• Straight tooth configuration for clean, conventional Woodruff keyseat milling
• 0.625 inch cutter diameter and 0.1875 inch cutting width conform to ANSI Standard 605
• 1/2 inch straight shank for compatibility with standard collets and milling arbors
• Bright, uncoated finish suitable for use with cutting fluid on a wide range of workpiece materials
• 8-tooth design balances chip clearance with cutting stability

Compatibility

Designed as a standard ANSI 605 Woodruff keyseat cutter fitting 1/2 inch collets and straight-shank milling arbors used on manual knee mills and CNC vertical machining centers.

Installation Notes

Installation should be performed by a qualified machinist. Secure the shank firmly in a collet or milling chuck to the full recommended grip depth before cutting. Ensure the spindle and any power feeds are fully de-energized and the machine is in a safe, locked-out state before mounting or removing the cutter. Use an appropriate cutting fluid for the workpiece material to extend tool life and maintain dimensional accuracy.
