Harvey Tool 22552 Woodruff Keyseat Cutter 3/8 in

Product Description

The HARVEY TOOL 22552 is a solid carbide Woodruff keyseat cutter designed for milling keyseat slots in shafts and mating components. With a 0.375-inch cutting diameter and a 0.1-inch cutting width, this cutter produces precise, narrow keyseats in a single pass. The straight-tooth configuration and 8-flute design deliver clean chip evacuation and consistent slot geometry. The 3/8-inch shank diameter and 2.5-inch overall length make it compatible with standard milling setups. Solid carbide construction provides the rigidity and edge retention required when cutting steel, stainless steel, cast iron, and select non-ferrous materials. Machinists and tool-and-die professionals use this cutter in both manual and CNC milling applications.

This keyseat cutter is suited for keyseat operations on steel, stainless steel, and cast iron as primary workpiece materials. Secondary applications include non-ferrous metals, superalloys, titanium, and hard materials. The bright, uncoated finish makes it appropriate for general-purpose cutting where coating is not required. Typical use cases include shaft keyway preparation in machine rebuilding, OEM component manufacturing, and precision maintenance work where exact slot width is critical.

Key Features

• 0.375-inch cutting diameter with 0.1-inch cutting width for narrow, precise keyseats
• 8 straight teeth for clean chip evacuation and consistent slot finish
• 0.187-inch neck diameter and 0.562-inch neck length allow clearance in deep or interrupted cuts
• 3/8-inch shank diameter fits standard ER collets and milling chucks
• Bright, uncoated finish suitable for a broad range of workpiece materials

Compatibility

Designed for use on steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and hard materials. Fits standard 3/8-inch collets and milling chucks used in vertical milling machines and CNC machining centers.

Installation Notes

Installation and use of this cutter should be performed by a qualified machinist. Secure the 3/8-inch shank firmly in a matched collet or end mill holder before operation, and verify runout before cutting. Set spindle speed and feed rate according to the workpiece material and cutter manufacturer guidelines — do not exceed the rated cutting depth for the 0.1-inch width. Inspect the cutter for chipping or wear before each use, as solid carbide tooling is brittle and should not be used if any edge damage is present.
