Harvey Tool 898593-C3 Woodruff Keyseat Cutter Altin

Product Description

The HARVEY TOOL 898593-C3 is a solid carbide Woodruff keyseat cutter designed for precision keyway and keyseat milling in metalworking applications. It features a 0.5-inch cut diameter and a 0.1874-inch (3/16 inch) cut width, with a straight-tooth configuration that delivers clean, consistent cuts. The cutter carries an AlTiN coating for improved heat resistance and tool life at elevated cutting speeds. With 6 teeth and a 0.5-inch shank diameter, it is suited for use in CNC machining centers and manual knee mills operated by skilled machinists and toolroom professionals.

This cutter is intended for keyseat and Woodruff key slot operations in ferrous and non-ferrous materials. Primary workpiece materials include steel, stainless steel, and cast iron. Secondary applications cover non-ferrous metals, superalloys, titanium, and hard materials. The 3-inch overall length and 0.156-inch neck diameter allow access to keyseat profiles where standard end mills cannot reach. It is commonly used in job shops, maintenance facilities, and production environments where tight keyway tolerances are required.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard and abrasive materials
• AlTiN coating improves oxidation resistance and extends tool life at higher cutting speeds
• 0.5-inch cut diameter with 0.1874-inch cut width for standard 3/16-inch Woodruff key slots
• Straight-tooth configuration provides stable cutting action in keyseat profiles
• 6-flute design balances chip evacuation with surface finish quality
• 0.156-inch neck diameter allows reach into recessed or deep keyseat locations

Compatibility

Designed as an OEM-style keyseat cutter compatible with standard 1/2-inch straight shank tool holders. Suitable for primary workpiece materials including steel, stainless steel, and cast iron, with secondary suitability for non-ferrous metals, superalloys, titanium, and hard materials.

Installation Notes

Installation and operation should be performed by qualified machinists familiar with CNC or manual milling equipment. Ensure the tool holder and spindle are clean and properly torqued before use. Always power down and lock out the machine before changing cutters. Verify correct speeds and feeds for the workpiece material and coating type before engaging the cut.
