Harvey Tool 69420 Woodruff Keyseat Cutter 0.1562 in

Product Description

The HARVEY TOOL 69420 is a solid carbide Woodruff keyseat cutter designed for milling keyseat slots in shafts and bores. It features a 0.1562-inch cutting diameter and a 0.02-inch cutting width, making it suited for precision keyway applications where tight tolerances are required. The straight tooth configuration provides clean, accurate cuts. With a 3/16-inch shank diameter and a 2-inch overall length (OAL), this cutter is used in CNC machining centers and manual mills. The uncoated bright finish is standard for solid carbide tooling at this scale. Machinists and tool-and-die professionals are the primary users of this cutter.

This cutter is applied in small-diameter shaft keyseating operations found in precision mechanical assemblies, including drive shaft components, gear hubs, and similar workpieces requiring Woodruff key slots. It is well suited for use in CNC vertical machining centers and conventional knee mills where a 3/16-inch shank collet or chuck is available. The 0.02-inch cutting width corresponds to 0.50 mm, appropriate for metric-equivalent keyseat dimensions. Both job shops and production environments use this style of cutter for high-repeatability slotting work in steel, aluminum, and similar machinable materials.

Key Features

Compatibility

Designed as an OEM-style Woodruff keyseat cutter for use in CNC and manual milling applications requiring a 3/16-inch shank and a 0.1562-inch cutting diameter.

Installation Notes

Installation is performed by a qualified machinist. Secure the 3/16-inch shank firmly in a collet or end mill holder before operation; verify runout with a dial indicator before cutting. Power down the spindle completely before tool changes. Follow the machine tool manufacturer's recommended feeds and speeds for solid carbide keyseat cutters at this diameter to avoid tool breakage.
