Harvey Tool 71150-C3 Woodruff Keyseat Cutter Solid Carbide Altin

Product Description

The HARVEY TOOL 71150-C3 is a solid carbide Woodruff keyseat cutter designed for milling keyseat slots in shafts and workpieces where precise width and depth control are critical. It features a 0.375-inch cutting diameter and a 0.093-inch cutting width, with a straight-tooth configuration that delivers clean, accurate cuts. The AlTiN coating improves hardness and heat resistance at the cutting edge, extending tool life in demanding machining applications. With 8 teeth and an overall length of 2.5 inches, this cutter is suited for use in CNC machining centers and manual mills by machinists and tool and die professionals.

This keyseat cutter is used in metalworking operations that require slot milling for Woodruff keys in shaft assemblies. Typical applications include manufacturing and repair of drive shafts, spindles, and machine components where keyed connections are specified. The 3/8-inch shank diameter fits standard collets and tool holders found on vertical milling machines and CNC machining centers. It is intended for professional machinists working in production shops, job shops, and maintenance environments.

Installation Notes

Installation and use should be performed by qualified machinists familiar with milling operations and cutting tool safety. Ensure the machine spindle is fully stopped and locked out before mounting or removing the cutter. Secure the shank firmly in a properly sized collet or end mill holder to the tool holder manufacturer's specified torque range. Follow shop safety protocols and wear appropriate PPE during all machining operations.
