Harvey Tool 27325-C3 Woodruff Keyseat Cutter Solid Carbide

Product Description

The HARVEY TOOL 27325-C3 is a solid carbide Woodruff keyseat cutter designed for milling semicircular keyseats in shafts and mating components. It features a 0.078-inch cutting diameter and a 0.025-inch cutting width, making it suited for small, precise keyseat profiles. The AlTiN coating improves heat and wear resistance, extending tool life in ferrous and hard-material applications. With a straight-tooth configuration and 4 flutes, this cutter delivers clean, consistent cuts in tight-tolerance machining environments. It is installed via a 0.125-inch straight shank and is handled by machinists and toolroom professionals on CNC mills and manual knee mills.

This cutter is intended for use on steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and hard materials. It is well suited to precision shaft work in job shop, production machining, and maintenance machining environments where small-diameter keyseat geometry is required. The compact 1.5-inch overall length allows use in setups with limited clearance. Its solid carbide construction and AlTiN finish make it a practical choice when cutting harder workpiece materials where high-speed steel tooling would wear prematurely.

Key Features

• Solid carbide construction for rigidity and wear resistance in ferrous and hard-material cuts
• AlTiN coating provides elevated heat resistance and extended tool life
• 0.078-inch cutting diameter with 0.025-inch cutting width for precise small-profile keyseats
• Straight-tooth configuration with 4 teeth for consistent chip formation
• 0.039-inch neck diameter and 0.118-inch neck length for reach into narrow slots
• 1/8-inch straight shank for compatibility with standard collet systems

Compatibility

Designed for use on steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and hard materials. Fits standard 1/8-inch collets and tool holders used on CNC machining centers and manual milling machines.

Installation Notes

Installation is performed by a qualified machinist. Secure the shank in a clean, properly sized collet or end mill holder and verify runout before cutting. Power down and lock out the spindle before changing tooling. Follow the tool manufacturer and machine builder guidelines for feeds, speeds, and depth of cut appropriate to the workpiece material and machine rigidity.
