Value Collection C2100811 Woodruff Keyseat Cutter

Product Description

The VALUE COLLECTION C2100811 is a Woodruff keyseat cutter designed for milling semicircular keyseats into shafts and bores. Built from M42 cobalt high-speed steel, this cutter delivers extended tool life in tough materials where standard HSS cutters wear prematurely. It has a 1.375-inch cut diameter and a 0.25-inch cutting width, producing a precise Woodruff key slot in a single pass. The bright, uncoated finish keeps tolerances consistent and simplifies inspection. Machinists and tool-and-die technicians use this cutter on manual mills and CNC machining centers when producing keyed shaft assemblies to ANSI standard specifications.

This cutter suits general machining operations where Woodruff key slots are required on rotating shafts, spindles, and similar components. The straight-tooth configuration is well suited to light-to-medium-duty slotting operations in steel, aluminum, and similar machinable materials. It conforms to ANSI 811 (Old Standard No. 22), making it a direct fit wherever that standard is called out on a print. The 0.5-inch shank diameter accommodates standard milling machine arbors and collet chucks commonly found in job shops and production environments.

Key Features

• M42 cobalt construction for improved heat and wear resistance over standard HSS
• 1.375-inch cut diameter with 0.25-inch cutting width for Woodruff key slot production
• Straight-tooth configuration for clean, consistent slotting cuts
• Conforms to ANSI 811, Old Standard No. 22
• Bright, uncoated finish for dimensional accuracy and easy inspection
• 14 teeth for smooth chip load distribution

Compatibility

Designed as an OEM-style replacement or production tooling option for machining applications requiring an ANSI 811 Woodruff keyseat cutter with a 0.5-inch shank diameter.

Installation Notes

Installation is performed by qualified machinists. Secure the shank in a properly sized arbor or collet chuck and verify runout before cutting. Always power down and lock out the machine spindle before changing or adjusting cutters. Follow the machine manufacturer's recommended feed and speed guidelines for cobalt tooling in the workpiece material being machined.
