Harvey Tool 905250-C3 Woodruff Keyseat Cutter Solid Carbide

Product Description

The HARVEY TOOL 905250-C3 is a brazed solid carbide Woodruff keyseat cutter designed for milling keyseat slots in shafts and workpieces across a range of ferrous and non-ferrous materials. It features a 0.75-inch cut diameter, a 0.125-inch cutting width, and a 3/8-inch shank diameter, with a 3.125-inch overall length. The cutter carries 10 straight teeth and an AlTiN coating for improved heat resistance and tool life in demanding cutting conditions. This tool is installed and operated by machinists and tool-and-die professionals working on CNC mills or manual knee mills.

This keyseat cutter is suited for producing Woodruff keyseats in steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and hard materials. Typical applications include shaft-to-hub keyway preparation in precision machining environments, both in job shops and production facilities. The straight tooth configuration provides clean, controlled cuts in the slot profile. The shank connects directly to standard collet or end mill holders with a 3/8-inch bore.

Key Features

• Brazed solid carbide construction for rigidity and wear resistance
• AlTiN coating improves performance in steel, stainless steel, and high-temp alloys
• 0.75-inch cut diameter with 0.125-inch cutting width for precise keyseat profiles
• 10 straight teeth for consistent chip formation and slot finish
• 0.030-inch corner radius for controlled edge transition
• 3/8-inch shank compatible with standard collet holders — no Weldon flat

Compatibility

Designed for use in CNC machining centers and manual milling machines accepting a 3/8-inch shank. Primary workpiece materials include steel, stainless steel, and cast iron. Secondary workpiece materials include non-ferrous metals, superalloys, titanium, and hard materials.

Installation Notes

Installation is performed by qualified machinists. Secure the shank in a clean, properly sized collet or end mill holder and torque the drawbar or clamping mechanism to the machine specification before cutting. Ensure the spindle is fully stopped and locked out before changing or inspecting the cutter. Do not exceed the recommended speeds and feeds for the workpiece material and cutter diameter as specified by the manufacturer.
