Value Collection C1100809 Woodruff Keyseat Cutter Hss

Product Description

The VALUE COLLECTION C1100809 is a Woodruff keyseat cutter designed for milling the semicircular keyway slots used in shaft-and-hub assemblies. Built from high speed steel with a bright, uncoated finish, it delivers consistent cutting performance on steel, cast iron, and similar materials. The cutter measures 1.125 inches in diameter with a 0.25 inch cut width and mounts on a 0.5 inch diameter shank. Twelve straight teeth provide a clean, stable cut in both manual and CNC milling applications. Machinists and tool-and-die workers select this cutter when producing Woodruff keyseats to ANSI 809 specifications, formerly referenced as Old Standard Number 18.

This cutter is suited for use in vertical milling machines, horizontal mills, and milling attachments where Woodruff keyway slots are required in shafts, gears, and hubs. The straight-tooth configuration performs reliably in general-purpose keyseat operations across job shops, maintenance facilities, and production environments. It is appropriate for ferrous and non-ferrous workpiece materials within the feed and speed limits of high speed steel tooling.

Key Features

• 1.125 inch cut diameter meets ANSI 809 Woodruff keyseat standard (Old Standard Number 18)
• 0.25 inch cut width for precise keyway slot sizing
• High speed steel construction for durability across a range of workpiece materials
• 12 straight teeth for stable, clean cutting action
• Bright, uncoated finish — no coating buildup to affect dimensional accuracy
• 0.5 inch shank diameter for broad compatibility with standard milling machine collets and arbors

Compatibility

Designed as a standard Woodruff keyseat cutter for use in milling machines equipped with a 0.5 inch collet or arbor bore, conforming to ANSI 809 and Old Standard Number 18 dimensional requirements.

Installation Notes

Installation and use of this cutter should be performed by qualified machinists familiar with milling machine operation. Secure the shank firmly in a clean, properly sized collet or arbor before beginning the cut, and verify spindle runout is within acceptable limits. Always power down and lock out the machine before changing tooling. Follow established feeds-and-speeds guidelines for high speed steel cutters on the target workpiece material to avoid tool deflection or premature wear.
