Harvey Tool 26420-C3 Woodruff Keyseat Cutter Altin Carbide

Product Description

The HARVEY TOOL 26420-C3 is a solid carbide Woodruff keyseat cutter designed for cutting keyseat slots in shafts and mechanical components. It features a 0.062 inch cutting diameter, a 0.02 inch cutting width, and a 1/8 inch straight shank. The straight-tooth configuration and AlTiN coating make this cutter well suited for high-speed milling in ferrous and hardened materials. At 1.5 inches overall length with 4 cutting teeth, this tool is built for precision slotting work on CNC machining centers and manual mills. Machinists and tool-and-die professionals are the primary users.

This keyseat cutter is used in job shops, production machining environments, and maintenance facilities where shaft keyseating operations are performed. It is appropriate for creating Woodruff key slots in mild steel, alloy steel, stainless steel, and similar materials. The small cut diameter and narrow cut width make it suitable for miniature shaft work and tight-tolerance keyseat applications where a standard end mill cannot provide the correct slot profile.

Key Features

• Solid carbide construction for rigidity and wear resistance in demanding materials
• AlTiN coating extends tool life and supports higher cutting speeds in ferrous alloys
• 0.062 inch cutting diameter with 0.02 inch cutting width for tight-tolerance keyseat slots
• Straight-tooth design provides clean, stable cutting action
• 4-flute geometry balances chip evacuation and surface finish
• 1/8 inch shank fits standard collets and toolholders common in CNC and manual milling setups

Compatibility

Designed as an OEM-style Woodruff keyseat cutter for use in standard 1/8 inch collet toolholders on CNC machining centers and manual knee mills performing keyseat slotting operations.

Installation Notes

Installation is performed by qualified machinists following standard toolholding procedures. Ensure the collet and toolholder are clean and properly torqued before initiating a cut. Verify spindle speed and feed rate are appropriate for the workpiece material and cutter diameter before engaging the cut. Do not exceed the rated cutting width in a single pass on hardened materials.
