Harvey Tool 987730 Woodruff Keyseat Cutter 0.5 in Solid Carbide

Product Description

The HARVEY TOOL 987730 is a solid carbide Woodruff keyseat cutter designed for milling the semicircular keyseats used in shaft-and-hub assemblies. It features a 0.5-inch cutting diameter, a 0.062-inch (1/16-inch) cutting width, and a 1/2-inch shank diameter. The straight-tooth configuration and uncoated bright finish are suited for precise keyseat profiles in a range of workpiece materials. With 8 teeth and a 3-inch overall length, this cutter is built for controlled, repeatable cuts in manual and CNC milling applications. Machinists, toolmakers, and precision machine shops are the primary users of this tool.

This keyseat cutter is used in machining operations where a Woodruff key slot must be cut into a rotating shaft or mating component. It is appropriate for both prototype work and production runs in job shops, maintenance machining, and manufacturing environments. The 1/2-inch shank allows direct mounting in standard end-mill holders and collet chucks on vertical milling machines and machining centers. The 0.062-inch cutting width corresponds to standard Woodruff key sizing commonly specified in mechanical assemblies.

Key Features

• Solid carbide construction for rigidity and wear resistance in keyseat milling
• 0.5-inch cutting diameter with 0.062-inch (1/16-inch) cutting width for standard Woodruff key profiles
• 8 straight teeth for clean, accurate keyseat geometry
• 1/2-inch shank diameter compatible with standard end-mill holders and collet chucks
• 3-inch overall length provides clearance for most shaft and workpiece setups
• Bright uncoated finish maintains dimensional accuracy and suits a broad range of materials

Compatibility

Designed as a direct-fit Woodruff keyseat cutter for use in standard 1/2-inch end-mill holders and collet chucks on vertical milling machines and CNC machining centers. Specific machine or system compatibility was not stated in the product data.

Installation Notes

Installation is performed by qualified machinists. Secure the 1/2-inch shank in a properly sized collet or end-mill holder and torque the holder to the machine manufacturer's specification. Power down and lock out the spindle before loading or removing the cutter. Use appropriate speeds and feeds for solid carbide tooling based on the workpiece material; running carbide cutters at speeds intended for high-speed steel tooling will cause premature failure.
