Harvey Tool 899840-C3 Woodruff Keyseat Cutter 0.75in Altin

Product Description

The HARVEY TOOL 899840-C3 is a Woodruff keyseat cutter designed for milling keyseat slots in shafts and workpieces that require precise, tight-tolerance key fits. Built from brazed solid carbide and finished with an AlTiN coating, this cutter delivers hardness and heat resistance suited for ferrous and non-ferrous machining applications. It features a 0.75 inch cut diameter, a 0.093 inch cut width, and a 1/4 inch shank diameter with a Weldon flat for secure tool holding. Machinists and tool-and-die professionals install this cutter on CNC milling machines and manual knee mills where keyway accuracy is critical.

This keyseat cutter is used in precision machining environments for cutting Woodruff keyseats in round stock, shafts, and bores. The straight tooth configuration produces clean, square-sided slots suited to standard Woodruff key fits. With an overall length of 3.094 inches and 10 teeth, it is appropriate for light to moderate depth-of-cut passes where dimensional accuracy and surface finish take priority. It is commonly specified in job shops, production machine shops, and maintenance machining operations.

Key Features

• Brazed solid carbide construction for rigidity and wear resistance
• AlTiN coating improves heat resistance and tool life in ferrous materials
• Straight tooth configuration produces clean, square keyseat walls
• Weldon flat on 1/4 inch shank prevents tool pullout under cutting loads
• 10-tooth design balances chip clearance with cutting edge count
• 0.093 inch cut width matches standard Woodruff key dimensions

Compatibility

Designed as a direct-fit Woodruff keyseat cutter for use in standard 1/4 inch shank tool holders on CNC and manual milling machines. No specific compatible model numbers were provided in the product data.

Installation Notes

Installation is performed by qualified machinists. Secure the 1/4 inch shank firmly in a collet or end mill holder, ensuring the Weldon flat is engaged with the set screw to prevent axial slippage. Power down and lock out the machine spindle before mounting or removing the cutter. Avoid side loading beyond the rated cut width, and use appropriate cutting fluid or coolant for the workpiece material to maximize tool life.
