Harvey Tool 987780 Woodruff Keyseat Cutter Solid Carbide

Product Description

The HARVEY TOOL 987780 is a solid carbide Woodruff keyseat cutter designed for milling Woodruff keyseats in shafts and mating keyways in hubs. With a 0.5-inch cutting diameter and a 0.25-inch cutting width, this cutter produces precise, dimensionally accurate keyseats in a single pass. The straight-tooth configuration and solid carbide construction deliver clean cuts and long tool life in steel, aluminum, and other machinable alloys. The 0.5-inch shank diameter and 3-inch overall length make it compatible with standard milling setups. Machinists and tool-and-die technicians are the primary users of this cutter in both production and maintenance environments.

This cutter is suited for vertical and horizontal milling machine applications where Woodruff-style keyseat profiles are required. It is appropriate for both manual mills and CNC machining centers running at feeds and speeds appropriate for solid carbide end mills. Typical applications include shaft preparation in mechanical assemblies, power transmission components, and precision fixturing work. The bright, uncoated finish is well suited for non-ferrous materials and general-purpose ferrous applications where a specialized coating is not required.

Key Features

• Solid carbide construction for rigidity and extended tool life compared to HSS alternatives
• 0.5-inch cutting diameter with 0.25-inch cutting width for standard Woodruff keyseat profiles
• Straight-tooth configuration for clean, efficient material removal
• 8 teeth provide a good balance of chip clearance and cut smoothness
• Bright, uncoated finish suitable for general-purpose and non-ferrous milling
• 3-inch overall length with a 0.5-inch shank fits standard collet and end mill holders

Compatibility

Designed as an OEM-style Woodruff keyseat cutter for use in standard milling machine setups accepting a 1/2-inch shank diameter tool holder or collet.

Installation Notes

This cutter is installed and operated by machinists using standard collet chucks or end mill holders rated for the 0.5-inch shank diameter. Ensure the spindle and workpiece are fully secured before engaging the cutter. Set feeds and speeds appropriate for solid carbide tooling and the specific workpiece material before beginning the cut. Inspect the cutter for chips or edge damage before each use, as carbide is brittle and can fracture if run with pre-existing damage.
