Harvey Tool 70893-C3 Woodruff Keyseat Cutter Solid Carbide Altin

Product Description

The HARVEY TOOL 70893-C3 is a Woodruff keyseat cutter designed for milling the semicircular keyway slots used in shaft-and-hub assemblies. It features a 0.25-inch cut diameter, a 0.093-inch cutting width, and a 1/4-inch shank diameter, with an overall length of 2.5 inches. The cutter is manufactured from solid carbide and carries an AlTiN coating, which improves heat resistance and tool life when cutting ferrous and hard materials. With 6 straight teeth and a neck diameter of 0.078 inches, it is suited for accurate, repeatable keyseat milling on CNC machining centers and manual mills. This tool is installed and operated by machinists and toolroom technicians working in precision manufacturing environments.

This keyseat cutter is intended for use on steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and hard materials. It is well suited for applications requiring tight-tolerance keyway slots in rotating shafts, hubs, and mechanical drive components. The small neck diameter of 0.078 inches allows the cutter to reach into confined areas without interference. Typical applications include production machining of power transmission components in aerospace, industrial equipment, and general manufacturing where keyway geometry must meet precise dimensional requirements.

Key Features

• Solid carbide construction provides rigidity and wear resistance for consistent cut quality
• AlTiN coating extends tool life in high-temperature cutting conditions on ferrous and hard materials
• 0.25-inch cut diameter with 0.093-inch cutting width for standard Woodruff keyseat profiles
• 6 straight teeth deliver clean, accurate slot geometry
• 0.078-inch neck diameter enables reach into tight or restricted workpiece geometry
• 1/4-inch shank diameter compatible with standard collets and tool holders

Compatibility

Designed as an OEM-style keyseat cutter for use in standard 1/4-inch collet or end mill holders on CNC machining centers and manual milling machines. Suitable for workpiece materials including steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and hard materials.

Installation Notes

Installation and operation should be performed by a qualified machinist. Secure the 1/4-inch shank in a properly sized collet or Weldon-style tool holder and verify runout before cutting. Ensure the machine spindle is fully stopped before tool changes. Follow the cutter manufacturer's recommended speeds and feeds for the specific workpiece material and coating type to avoid premature tool wear or breakage.
