Keo 943-000-281 Woodruff Keyseat Cutter 1.375 in

Product Description

The KEO 943-000-281 is a Woodruff keyseat cutter designed for milling Woodruff keyseats in shafts and other precision workpieces. It features a 1.375 inch cutting diameter, a 0.25 inch cutting width, and a straight tooth configuration with 14 teeth. The cutter is made from high speed steel with a bright uncoated finish. The 0.5 inch straight shank connects directly to a standard milling machine spindle or collet chuck. This tool is used by machinists and tool-and-die professionals in shops handling general manufacturing, maintenance machining, and repair work.

This keyseat cutter is suited for slotting Woodruff keyseats in a wide range of workpiece materials including steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium. It meets ANSI standard 811 and corresponds to Old Standard Number 22. The 2.25 inch overall length and 0.375 inch neck length make it compatible with typical vertical milling setups where reach and rigidity are both important considerations.

Compatibility

Designed as a standard Woodruff keyseat cutter conforming to ANSI 811 (Old Standard Number 22), compatible with vertical milling machines using 0.5 inch collet or shank toolholding systems.

Installation Notes

Installation is performed by qualified machinists on vertical milling machines. Secure the shank firmly in a collet chuck or end mill holder before beginning any cut, and verify machine spindle speed is appropriate for the cutter diameter and workpiece material. Always power down and lock out the machine before changing or inspecting the cutter. Do not use this cutter on a machine with excessive spindle runout, as this will accelerate tooth wear and produce out-of-tolerance keyseats.
