Harvey Tool 71240-C3 Woodruff Keyseat Cutter Solid Carbide

Product Description

The HARVEY TOOL 71240-C3 is a solid carbide Woodruff keyseat cutter designed for milling keyseat slots in shafts and bores. It features a 0.5-inch cutting diameter and a 0.078-inch cutting width, making it suited for precise, narrow slot work where dimensional accuracy is critical. The AlTiN coating extends tool life in harder workpiece materials by reducing heat buildup at the cutting edge. With 8 straight teeth and a 3-inch overall length, this cutter delivers clean, repeatable cuts in both conventional and CNC milling setups. Machinists and tool-and-die professionals working in metalworking, automotive, and general manufacturing rely on this style of cutter for keyseat production.

This Woodruff keyseat cutter is used in horizontal and vertical milling operations where keyseat slots must be cut to tight tolerances. The straight tooth configuration makes it appropriate for standard keyseat applications in steel, aluminum, and similar machinable metals. The 0.5-inch shank diameter provides solid tool holding in standard collets and end mill holders. It is a single-piece solid carbide construction, which delivers greater rigidity and edge retention compared to high-speed steel alternatives, particularly in production environments where tool consistency matters across multiple parts.

Key Features

• Solid carbide construction for increased rigidity and edge retention
• AlTiN coating reduces heat buildup and extends tool life in ferrous and harder materials
• 0.5-inch cutting diameter with 0.078-inch cutting width for narrow keyseat slots
• 8 straight teeth for clean, repeatable slot milling
• 3-inch overall length accommodates standard milling setups
• 0.5-inch shank diameter fits standard collets and end mill holders

Compatibility

Designed as an OEM-style keyseat cutter for use in standard vertical and horizontal milling machines equipped with a 0.5-inch collet or end mill holder.

Installation Notes

Installation and use should be performed by a qualified machinist familiar with milling operations and tool holding systems. Ensure the spindle is fully stopped and the machine is powered down before changing or setting cutters. Secure the shank firmly in a properly sized collet or end mill holder before operation, and verify runout with a dial indicator when precision slot dimensions are required. Follow all applicable machine tool safety practices and shop safety guidelines during setup and operation.
