Harvey Tool 44660-C3 Woodruff Keyseat Cutter Staggered Tooth

Product Description

The HARVEY TOOL 44660-C3 is a Woodruff keyseat cutter designed for milling keyseats and slots in shafts and bores. Built from solid carbide and coated with AlTiN (aluminum titanium nitride), it delivers high hardness and heat resistance during interrupted and staggered-tooth cutting operations. The cutter measures 0.5 inches in diameter with a 0.125 inch cutting width and mounts on a 0.5 inch diameter shank. At 3 inches overall length with 8 staggered teeth, it produces clean, accurate keyseat profiles in ferrous and non-ferrous materials. Machinists and toolmakers are the primary users of this tool in CNC machining and manual milling environments.

This cutter is suited for keyseat milling in precision shaft work across industrial manufacturing, maintenance machining, and job shop applications. The staggered tooth configuration reduces cutting forces and chatter compared to straight-tooth designs, making it appropriate for both full-width slotting and side milling of keyways. The AlTiN coating extends tool life at elevated cutting temperatures, supporting higher surface footage in steel and alloy materials. It is used in both vertical milling machines and CNC machining centers where a 0.5 inch shank is accepted.

Key Features

• Solid carbide construction for rigidity and wear resistance
• AlTiN coating provides heat resistance and extended tool life in ferrous materials
• Staggered tooth configuration reduces cutting forces and minimizes chatter
• 0.125 inch cutting width produces standard Woodruff keyseat profiles
• 8-tooth design for smooth, consistent chip load per tooth
• 0.5 inch shank diameter for direct collet or end mill holder mounting

Compatibility

Designed for use in vertical milling machines and CNC machining centers accepting a 0.5 inch shank connection. Suitable for keyseat milling applications in ferrous and non-ferrous workpiece materials.

Installation Notes

This tool is installed and operated by machinists in milling machines and CNC machining centers. Secure the 0.5 inch shank in a properly sized collet or end mill holder and torque to the machine spindle specification before running. Ensure the workpiece is firmly clamped and the machine spindle is at a full stop before changing or inspecting the cutter. Carbide tooling is brittle — avoid side loads or impacts during handling and setup.
