Harvey Tool 908580-C3 Woodruff Keyseat Cutter Solid Carbide

Product Description

The HARVEY TOOL 908580-C3 is a solid carbide Woodruff keyseat cutter designed for milling keyseat slots in shafts and workpieces that accept Woodruff keys. The cutter measures 0.625 inches in diameter with a 0.25 inch cutting width and mounts on a 0.625 inch shank. It features a straight tooth configuration with 8 teeth and an AlTiN (aluminum titanium nitride) coating that extends tool life in ferrous and hardened materials. Overall length is 3.5 inches. This tool is installed and run by machinists and CNC tooling specialists working in precision machining environments.

This keyseat cutter is suited for creating Woodruff key slots on shafts in both manual mill and CNC machining center applications. The straight tooth geometry provides clean, full-width cuts in a single pass. The AlTiN finish supports dry or semi-dry cutting conditions, making it appropriate for production environments where coolant use is limited or where higher cutting temperatures are expected. It is commonly used in job shops, production facilities, and maintenance machining operations where shaft keyway work is routine.

Key Features

• Solid carbide construction for rigidity and extended tool life compared to HSS alternatives
• AlTiN coating improves heat resistance and wear resistance in ferrous and hardened materials
• Straight tooth configuration with 8 teeth delivers consistent full-width keyseat cuts
• 0.625 inch cut diameter and 0.25 inch cut width sized for standard Woodruff key slots
• 0.625 inch shank diameter for secure, concentric tool holding in standard collets or end mill holders
• 3.5 inch overall length provides adequate reach for most shaft keyseating setups

Compatibility

Designed as an OEM-style Woodruff keyseat cutter for use in standard milling machine spindles and CNC machining centers accepting a 0.625 inch shank via collet or end mill holder.

Installation Notes

This cutter should be installed by a qualified machinist familiar with milling operations and tool holder torque requirements. Ensure the machine spindle is fully stopped and locked out before mounting or removing the cutter. Seat the shank fully into a clean, undamaged collet or end mill holder to maintain concentricity and prevent pull-out under cutting loads. Verify spindle speed and feed rate against the manufacturer recommendations for solid carbide keyseat cutters before engaging the workpiece.
