Harvey Tool 55920 Woodruff Keyseat Cutter 1 in Carbide

Product Description

The HARVEY TOOL 55920 is a Woodruff keyseat cutter designed for milling keyseat slots in shafts and mechanical components. It features a 1-inch cut diameter and a 0.062-inch cut width, making it suited for producing precise keyseat profiles in a single pass. The cutter is constructed from brazed solid carbide, delivering hardness and wear resistance for use in steel, cast iron, aluminum, and similar materials. With 12 straight teeth and a bright, uncoated finish, it provides clean, consistent cuts. A Weldon flat on the 1/2-inch shank helps secure the tool against rotational slippage in standard end mill holders. Machinists and tool-and-die professionals install this cutter on vertical mills and machining centers.

This keyseat cutter is used in precision machining applications where Woodruff key slots must be cut to tight tolerances in shaft work. It is appropriate for job shops, tool rooms, and production environments handling mechanical assemblies that require keyed shaft connections. The straight tooth configuration is well suited for conventional milling operations on a wide range of workpiece materials. At 3-1/16 inches overall length, it accommodates standard tool holder setups without excessive overhang.

Key Features

• 1-inch cut diameter with 0.062-inch cut width for standard Woodruff keyseat profiles
• Brazed solid carbide construction for hardness and extended tool life
• 12 straight teeth for consistent chip formation and clean slot walls
• Weldon flat on 1/2-inch shank resists rotational pullout in end mill holders
• Bright, uncoated finish suitable for use with or without cutting fluid
• 3-1/16-inch overall length fits standard vertical mill and machining center setups

Compatibility

Designed as a direct-fit replacement-style Woodruff keyseat cutter for use in standard 1/2-inch end mill holders and collet chucks on vertical milling machines and CNC machining centers.

Installation Notes

A licensed machinist or qualified toolroom technician should install this cutter. Secure the shank fully in a Weldon-style or set-screw end mill holder, engaging the flat to prevent slipping under load. Ensure the spindle is fully stopped and de-energized before mounting or removing the cutter. Verify runout with a dial indicator before cutting to avoid premature tool wear or dimensional error.
