Harvey Tool 70960-C3 Woodruff Keyseat Cutter Solid Carbide

Product Description

The HARVEY TOOL 70960-C3 is a solid carbide Woodruff keyseat cutter designed for milling keyseat slots in shafts and mating components. It features a 0.625 inch cut diameter and a 0.125 inch cut width, making it suited for producing precise Woodruff key profiles in a single pass. The straight tooth configuration and AlTiN coating combine to deliver clean slot geometry and extended tool life when cutting steel, stainless steel, cast iron, and select non-ferrous materials. With an overall length of 3.5 inches and a 0.625 inch shank diameter, it mounts directly in standard end mill holders or collet chucks on vertical mills and machining centers.

This cutter is intended for professional machinists and toolroom applications where accurate keyseat geometry is required on shafts, spindles, and hubs. It handles primary workpiece materials including steel, stainless steel, and cast iron, and is also rated for secondary materials such as non-ferrous metals, superalloys, titanium, and hard materials. The 0.312 inch neck diameter provides clearance for the cutter body during slot entry, and the 1.0 inch neck length allows adequate reach on most standard keyseat depths without interference.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard materials
• AlTiN coating extends tool life and supports higher cutting temperatures when machining steel and stainless steel
• Straight tooth design produces clean, accurate keyseat profiles
• 8-tooth configuration for balanced chip load and smooth cutting action
• 0.312 inch neck diameter provides clearance for slotting operations
• Compatible with standard Weldon-style end mill holders via 0.625 inch shank (no Weldon flat)

Compatibility

Designed as an OEM-style Woodruff keyseat cutter for use in vertical milling machines and CNC machining centers accepting a 0.625 inch shank diameter. Rated for steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and hard materials.

Installation Notes

Installation and operation should be performed by a qualified machinist familiar with milling cutter setup and speeds and feeds for carbide tooling. Ensure the machine spindle is fully stopped and locked out before mounting or removing the cutter. Secure the shank in a properly sized collet or end mill holder to the holder manufacturer's specified torque before cutting. Use appropriate cutting fluid or air blast as required by the workpiece material to prevent heat buildup and premature coating wear.
