Harvey Tool 55960 Woodruff Keyseat Cutter 1 in Solid Carbide

Product Description

The HARVEY TOOL 55960 is a Woodruff keyseat cutter designed for milling keyseat slots in shafts and bores. It features a 1-inch cut diameter and a 0.187-inch cut width, allowing precise slot sizing for standard Woodruff keys. The cutter is brazed solid carbide construction with a bright, uncoated finish and a straight-tooth configuration across 12 teeth. With a 1/2-inch shank diameter and an overall length of 3.187 inches, it mounts directly in standard end mill holders or collet chucks. This tool is suited for machinists and toolroom professionals working in production or maintenance environments.

This keyseat cutter is built for cutting Woodruff key slots in steel, stainless steel, and cast iron as primary workpiece materials. It also handles non-ferrous metals, superalloys, titanium, and hard materials as secondary applications. Typical use cases include shaft keyway work on motor, pump, and gearbox components in both job shop and production settings. The straight-tooth geometry provides stable, consistent cuts in these materials without requiring climb milling strategies.

Installation Notes

Install this cutter in a clean, properly sized 1/2-inch collet or Weldon-style holder and verify runout before cutting. Power down and lock out the machine spindle before mounting or removing the tool. Use appropriate cutting fluid for the workpiece material, especially when cutting stainless steel, cast iron, or superalloys. Inspect the brazed carbide head for integrity before each use and do not use if any cracks or separation are visible at the braze joint.
