Harvey Tool 68431-C3 Woodruff Keyseat Cutter Solid Carbide

Product Description

The HARVEY TOOL 68431-C3 is a Woodruff keyseat cutter designed for milling keyseat slots in shafts and bores. It features a 0.375-inch cut diameter and a 0.0624-inch cut width, making it suitable for cutting standard Woodruff key slots with tight dimensional tolerances. The cutter is manufactured from solid carbide and carries an AlTiN (aluminum titanium nitride) coating that improves wear resistance and extends tool life in ferrous and high-hardness workpiece materials. Six straight teeth provide consistent chip formation and surface finish. Licensed machinists and tool-and-die professionals are the primary installers of this tool.

This cutter is used in manual milling machines and CNC machining centers for generating Woodruff keyseat profiles in shafts, spindles, and mechanical assemblies. The 3/8-inch shank diameter fits standard collet chucks and end mill holders, making it compatible with common mill spindle setups in job shops, production environments, and maintenance machining applications. The 2.5-inch overall length provides adequate clearance for most keyseat-cutting scenarios without excessive overhang.

Key Features

• Solid carbide construction for rigidity and dimensional stability under cutting loads
• AlTiN coating enhances heat resistance and extends tool life in steel and alloy materials
• 0.375-inch cut diameter with 0.0624-inch cut width for precise Woodruff slot geometry
• Six straight teeth for clean chip evacuation and consistent slot surface finish
• 3/8-inch shank diameter compatible with standard collet and end mill holder systems
• 2.5-inch overall length suits typical shaft keyseat machining setups

Compatibility

Designed as an OEM-style replacement for Woodruff keyseat cutters used in standard 3/8-inch shank toolholders on manual mills and CNC machining centers.

Installation Notes

Install this cutter in a properly sized collet chuck or end mill holder rated for the 3/8-inch shank diameter, ensuring the holder is fully tightened before spindle operation. Confirm spindle speed and feed rate are appropriate for solid carbide tooling in the specific workpiece material before cutting. Never exceed the cutter's rated cut width in a single pass without confirming chip load recommendations for the material being machined. Follow standard machine shop lockout and guarding procedures when changing tooling.
