Harvey Tool 915860-C3 Woodruff Keyseat Cutter Solid Carbide

Product Description

The HARVEY TOOL 915860-C3 is a solid carbide Woodruff keyseat cutter designed for milling keyseat slots in rotating shafts and mechanical assemblies. It features a 0.375 inch cutting diameter, a 0.125 inch cutting width, and a 3/8 inch shank diameter. The staggered tooth configuration — 8 teeth total — reduces cutting forces and improves chip evacuation compared to straight-tooth designs. An AlTiN (aluminum titanium nitride) coating extends tool life at elevated cutting temperatures. Overall length is 2.5 inches. This tool is installed by machinists and tool-and-die professionals on manual mills and CNC machining centers.

The 915860-C3 is suited for keyseat work in steel, stainless steel, and cast iron as primary workpiece materials. It also handles non-ferrous metals, superalloys, titanium, and hard materials as secondary applications. The neck diameter of 0.188 inches and neck length of 0.563 inches provide clearance for slot entry without interference from the shank. Typical applications include shaft keyway production in power transmission components, gearboxes, and precision mechanical assemblies where tight slot tolerances are required.

Key Features

• Solid carbide construction for rigidity and wear resistance in ferrous and hard-material cutting
• AlTiN coating provides high heat resistance and extended tool life in dry or minimal-coolant operations
• Staggered tooth geometry with 8 teeth reduces cutting forces and improves surface finish
• 0.188 inch neck diameter and 0.563 inch neck length deliver slot-entry clearance on deep or offset keyseats
• 3/8 inch shank diameter for standard collet or end mill holder compatibility
• No Weldon flat — compatible with standard precision collet chucks

Compatibility

Designed for use in steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and hard materials. Fits any milling machine spindle or CNC machining center accepting a 3/8 inch shank via collet or end mill holder. Specific machine model compatibility was not provided in the product data.

Installation Notes

Installation is performed by qualified machinists on a vertical milling machine or CNC machining center. Secure the 3/8 inch shank in a clean, properly sized collet or end mill holder and verify runout before cutting. Confirm workpiece is rigidly fixtured before engaging the cutter to prevent chatter and tool deflection. Follow shop-specific speeds and feeds for the workpiece material and coating type; consult the manufacturer cutting data for AlTiN-coated carbide tooling.
