Harvey Tool 904593-C3 Woodruff Keyseat Cutter Solid Carbide

Product Description

The HARVEY TOOL 904593-C3 is a solid carbide Woodruff keyseat cutter designed for milling semicircular keyseats into shafts and bores in precision machining applications. It features a 0.25 inch cut diameter and a 0.093 inch cut width, making it suited for tight-tolerance keyseat profiles. The straight tooth configuration and AlTiN coating provide wear resistance and thermal stability during cutting. With 6 teeth and a 2.5 inch overall length, this cutter is sized for rigid setups on CNC milling machines and manual knee mills. It is installed and operated by machinists working in job shops, production environments, and maintenance machine shops.

This keyseat cutter is used in applications requiring accurate Woodruff key slots on shafts, spindles, and other rotating components. The 1/4 inch shank diameter allows it to seat in standard collet chucks and end mill holders commonly found on vertical milling machines. The AlTiN finish supports cutting in ferrous materials and alloys where heat generation is a concern. It is well suited for low-to-medium volume keyseat operations in both prototype and production machining contexts.

Key Features

• Solid carbide construction for rigidity and long tool life in precision keyseat milling
• AlTiN coating provides thermal and oxidation resistance for cutting ferrous and hardened materials
• 0.25 inch cut diameter with 0.093 inch cut width for standard Woodruff keyseat profiles
• Straight tooth configuration for clean, consistent chip formation in keyseat slots
• 6-tooth design balances chip load and surface finish in typical milling setups
• 1/4 inch shank diameter fits standard collet chucks and end mill holders

Compatibility

Designed as an OEM-style keyseat cutter for use in vertical milling machines and CNC machining centers accepting a 1/4 inch shank via collet or end mill holder.

Installation Notes

This cutter is installed and operated by qualified machinists. Ensure the machine spindle is fully stopped and power is locked out before changing tooling. Seat the shank fully and securely in the collet or holder to the recommended engagement depth before tightening. Do not exceed the cutter's rated depth of cut or feed rate for the workpiece material, and verify runout after tool installation to protect both the cutter and the workpiece.
