The HARVEY TOOL 987220-C3 is a solid carbide Woodruff keyseat cutter designed for milling keyseat slots in rotating shafts and mechanical components. It features a 0.375-inch cut diameter and a 0.047-inch cut width, producing precise half-moon keyway profiles in a single pass. The straight-tooth configuration and AlTiN coating make it well suited for cutting steel, stainless steel, and cast iron at extended tool life. With an 8-tooth design and 2.5-inch overall length, this cutter is used by machinists and toolroom technicians working on precision mechanical assemblies.
This keyseat cutter is intended for use on CNC milling machines and manual knee mills where keyseat operations are performed in shaft work. Primary workpiece materials include steel, stainless steel, and cast iron. Secondary applications cover non-ferrous metals, superalloys, titanium, and hard materials. The 3/8-inch shank diameter fits standard collets and end mill holders. The 0.187-inch neck diameter and 0.562-inch neck length provide clearance for cutting below shaft shoulders and into recessed areas.
Designed as a direct-fitment Woodruff keyseat cutter for use with 3/8-inch collets and standard end mill holders on CNC and manual milling machines. Suitable for primary workpiece materials including steel, stainless steel, and cast iron, and secondary materials including non-ferrous metals, superalloys, titanium, and hard materials.
Installation and operation should be performed by qualified machinists familiar with rotating cutter safety procedures. Secure the 3/8-inch shank fully in a collet or end mill holder before spindle engagement and verify runout before cutting. Power down and lock out the machine spindle before changing or inspecting the cutter. Do not exceed the cutter's rated depth of cut or chip load for the workpiece material being machined.
