Harvey Tool 947539 Woodruff Keyseat Cutter Solid Carbide

Product Description

The HARVEY TOOL 947539 is a solid carbide Woodruff keyseat cutter designed for milling keyseat slots in shafts and bores. It features a 0.2362-inch cutting diameter and a 0.039-inch cutting width, producing the narrow, radius-bottomed slots required for Woodruff keys in mechanical power transmission components. The straight tooth configuration provides clean, consistent cuts in a range of ferrous and non-ferrous materials. With a 1/4-inch shank diameter and a 2.5-inch overall length, this cutter mounts directly in standard collet chucks or milling arbors. Solid carbide construction delivers rigidity and wear resistance suited to precision slot work in production and toolroom environments.

This cutter is used in CNC machining centers and manual milling machines where Woodruff keyseat slots are required on shafts, hubs, or bores. Typical applications include the manufacture or repair of mechanical assemblies involving gears, pulleys, sprockets, and similar drive components. The compact 0.2362-inch cut diameter and 0.039-inch width make it appropriate for small-diameter shaft work where precise key fit and close tolerances are critical. Machinists, tool and die makers, and maintenance technicians working in general manufacturing, aerospace, and automotive environments are the primary users.

Key Features

• 0.2362-inch cutting diameter for small-shaft Woodruff keyseat applications
• 0.039-inch cutting width produces precise, narrow keyway slots
• Solid carbide construction for rigidity, wear resistance, and dimensional stability
• Straight tooth configuration with 6 teeth for consistent chip load and clean slot finish
• Bright/uncoated finish suitable for use with or without coolant across a range of workpiece materials
• 1/4-inch shank diameter compatible with standard collet and milling arbor setups

Compatibility

Designed for use in CNC machining centers and manual knee mills equipped with standard 1/4-inch collet chucks or milling arbors capable of holding straight-shank rotary cutting tools.

Installation Notes

This cutter is installed and operated by machinists or toolroom technicians on milling machines. Secure the 1/4-inch shank in a properly sized collet or arbor, ensuring full and even clamping engagement before starting the spindle. Never exceed the cutter manufacturer recommended speeds and feeds for the workpiece material. Inspect the cutting edges before each use and remove the cutter from service at the first sign of chipping or wear to avoid dimensional error or tool breakage.
