Harvey Tool 944439-C3 Woodruff Keyseat Cutter Solid Carbide

Product Description

The HARVEY TOOL 944439-C3 is a solid carbide Woodruff keyseat cutter designed for milling keyseat slots in shafts and workpieces across a wide range of metalworking applications. It features a 0.3125-inch cutting diameter, a 0.0788-inch cutting width, and a straight tooth configuration with 6 teeth. The AlTiN coating provides heat and wear resistance, extending tool life in demanding cutting environments. With a 0.3125-inch shank diameter and a 2.5-inch overall length, this cutter mounts directly into standard toolholders and is well-suited for CNC machining centers and manual milling machines operated by machinists and toolmakers.

This keyseat cutter is intended for use on steel, stainless steel, and cast iron as primary workpiece materials, and is also rated for non-ferrous metals, superalloys, titanium, and hard materials. It is commonly used in precision machining shops, maintenance and repair operations, and production environments where accurate keyseat geometry is required. The 0.1560-inch neck diameter and 0.5000-inch neck length allow for controlled reach into slots without excessive deflection.

Key Features

• Solid carbide construction for rigidity and wear resistance in metalcutting
• AlTiN coating improves thermal resistance and extends tool life in ferrous and hard materials
• 0.3125-inch cut diameter with 0.0788-inch cut width for precise keyseat slot sizing
• Straight tooth configuration with 6 teeth for clean, controlled cuts
• 0.1560-inch neck diameter and 0.5000-inch neck length provide clearance relief during slot milling
• 0.0394-inch corner radius reduces stress concentration at slot corners

Compatibility

Designed for use on steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and hard materials. Fits standard 5/16-inch shank toolholders and collets on CNC and manual milling machines.

Installation Notes

Installation and operation should be performed by a qualified machinist familiar with milling cutter safety and speeds-and-feeds selection. Ensure the toolholder is clean and the shank is fully seated before securing. Power down and lock out the machine spindle before changing cutters. Follow the cutter manufacturer and machine tool builder guidelines for appropriate RPM and feed rates based on workpiece material.
