Harvey Tool 44360-C3 Woodruff Keyseat Cutter Staggered Tooth

Product Description

The HARVEY TOOL 44360-C3 is a solid carbide Woodruff keyseat cutter designed for milling keyseat slots in shafts and workpieces where a precise, full-profile cut is required. It features a 0.5 inch cutter diameter, a 0.125 inch cutting width, and a staggered tooth configuration across 8 teeth for improved chip evacuation and reduced cutting forces. An AlTiN coating enhances heat resistance and tool life when cutting through ferrous and hard materials. The 0.5 inch shank diameter provides rigid tool holding in standard milling chucks and collets. This cutter is intended for use by machinists and tool-and-die professionals working on CNC milling centers or manual knee mills.

This keyseat cutter is suited for slotting operations in steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and hard materials. It fits applications in general machining, tool and die, and precision manufacturing where Woodruff key slots must meet tight dimensional tolerances. The 0.75 inch neck length provides clearance for deeper slot approaches without interference from the shank body. Overall length is 3 inches, making it compatible with standard tool holders used in both horizontal and vertical milling setups.

Key Features

• Staggered tooth configuration across 8 teeth for smoother cutting action and better chip flow
• AlTiN coating provides elevated heat resistance and extended tool life in ferrous and hard-material applications
• Solid carbide construction delivers rigidity and wear resistance compared to HSS alternatives
• 0.25 inch neck diameter with 0.75 inch neck length provides clearance for slotting operations
• 0.005 inch corner radius reduces stress concentration at slot corners
• 0.5 inch shank diameter fits standard ER and Weldon-style tool holders without a Weldon flat

Compatibility

Designed as an OEM-style keyseat cutter for use in standard 1/2 inch shank milling tool holders on CNC and manual milling machines. Rated for primary workpiece materials including steel, stainless steel, and cast iron, and secondary materials including non-ferrous metals, superalloys, titanium, and hard materials.

Installation Notes

Installation should be performed by a qualified machinist following standard milling tool change procedures. Ensure the spindle is fully stopped and the machine is in a safe state before inserting or removing the cutter. Secure the shank fully within the tool holder to the recommended engagement depth for the holder type in use. Verify runout with a dial indicator before beginning a cut, as excessive runout will accelerate edge wear on keyseat cutters.
