Harvey Tool 849370-C3 Woodruff Keyseat Cutter Altin

Product Description

The HARVEY TOOL 849370-C3 is a Woodruff keyseat cutter designed for milling keyseats and slots in shafts and bores. It features a 0.5 inch cut diameter and a 0.25 inch cut width, making it suited for precision slotting operations in metalworking and machining applications. The cutter is constructed from brazed solid carbide and carries an AlTiN coating for extended tool life in abrasive and high-heat cutting conditions. With 8 straight teeth and a 3.25 inch overall length, this cutter delivers clean, consistent slot geometry. A 0.25 inch shank with a Weldon flat provides secure tool holding in standard end mill holders.

This cutter is used in CNC machining centers and manual milling machines for cutting Woodruff keyseats in steel, stainless steel, cast iron, and similar ferrous materials. The AlTiN coating makes it well suited for dry or minimal-lubrication cutting environments. Typical applications include shaft keyway production in precision component manufacturing, tool and die work, and general machine shop use. It is installed and operated by machinists and CNC programmers working in job shop or production environments.

Key Features

• Brazed solid carbide construction for rigidity and wear resistance in hard materials
• AlTiN coating improves heat resistance and extends tool life in abrasive cutting conditions
• Straight tooth configuration produces clean keyseat geometry with consistent chip evacuation
• Weldon flat on 0.25 inch shank ensures positive tool retention in end mill holders
• 8 cutting teeth provide a balance of feed rate capability and finish quality
• 0.5 inch cut diameter and 0.25 inch cut width match standard Woodruff key dimensions

Compatibility

Designed for use in standard end mill holders and collet chucks accepting a 0.25 inch shank diameter with Weldon flat retention. Suitable for Woodruff keyseat milling operations on CNC machining centers and manual knee mills.

Installation Notes

Installation is performed by machinists using standard end mill holders with set screws aligned to the Weldon flat on the shank. Ensure the spindle is fully stopped and the machine is powered down before mounting or removing the cutter. Verify holder set screw torque per machine tool manufacturer specifications. Follow shop safety protocols and applicable OSHA machine guarding requirements during operation.
