Harvey Tool 973430-C3 Woodruff Keyseat Cutter Solid Carbide

Product Description

The HARVEY TOOL 973430-C3 is a solid carbide Woodruff keyseat cutter designed for milling keyseat slots in rotating shafts and mechanical components. It features a 0.3125-inch cut diameter and a 0.062-inch cut width, with a straight tooth configuration across 6 flutes for clean, controlled material removal. The AlTiN coating improves heat resistance and tool life when cutting ferrous and hard materials. The 5/16-inch shank diameter matches the cut diameter, and overall length is 2.5 inches. This cutter is intended for use by machinists and toolroom technicians on manual or CNC milling equipment.

This Woodruff keyseat cutter is suited for producing standard keyseat profiles in steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and hard materials. Its compact neck geometry - 0.109-inch neck diameter and 0.187-inch neck length - allows access into tight slot geometries. Typical applications include shaft keyway preparation in manufacturing, repair, and prototype machining environments where dimensional accuracy and surface finish are critical.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard and abrasive materials
• AlTiN coating provides elevated heat resistance and extended tool life in ferrous cutting applications
• Straight tooth configuration with 6 flutes for consistent chip formation and slot finish
• 0.109-inch neck diameter enables reach into narrow keyseat geometries
• 5/16-inch shank diameter with no Weldon flat for standard collet or end mill holder mounting
• 2.5-inch overall length suits most vertical milling setups

Compatibility

Designed for use in steel, stainless steel, and cast iron as primary workpiece materials, with secondary suitability for non-ferrous metals, superalloys, titanium, and hard materials. Compatible with standard 5/16-inch collets and end mill holders on manual or CNC milling machines.

Installation Notes

Installation and operation should be performed by qualified machinists familiar with milling cutter setup and speeds and feeds selection. Secure the shank fully in a collet or end mill holder before operation and verify runout before cutting. Power down and de-energize the spindle before tool changes. Do not exceed the cutter's rated depth of cut or use damaged tooling.
