Harvey Tool 23528-C3 Woodruff Keyseat Cutter Solid Carbide

Product Description

The HARVEY TOOL 23528-C3 is a solid carbide Woodruff keyseat cutter designed for cutting Woodruff keyseats and slots in ferrous and non-ferrous workpieces. It features a 0.375-inch cutting diameter, a 0.086-inch cutting width, and an 8-tooth straight tooth configuration. The AlTiN coating provides heat resistance and extended tool life during interrupted cuts and high-speed passes. With a 3/8-inch shank diameter and a 2.5-inch overall length, this cutter fits standard end mill holders and collet chucks found on CNC mills and manual knee mills. It is installed and operated by machinists and tool-and-die professionals performing precision shaft and keyway work.

This keyseat cutter is suited for slotting and undercutting operations on steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and hard materials. The straight tooth geometry is well matched to plunge-entry and side-milling passes in keyseat applications where a full-radius slot profile is required. The 0.187-inch neck diameter and 0.25-inch neck length provide the necessary clearance for undercutting operations without interference from the shank body.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard and abrasive materials
• AlTiN coating for elevated heat resistance and longer tool life in ferrous cutting applications
• 0.375-inch cutting diameter and 0.086-inch cutting width for precise Woodruff keyseat profiles
• 8 straight teeth for clean, consistent slot geometry
• 0.187-inch neck diameter with 0.25-inch neck length enables undercutting with shank clearance
• 3/8-inch shank diameter compatible with standard end mill holders and collet systems

Compatibility

Designed as an OEM-style replacement and standard production cutter for use in CNC machining centers and manual mills accepting a 3/8-inch straight shank. Rated for primary workpiece materials including steel, stainless steel, and cast iron, with secondary suitability for non-ferrous metals, superalloys, titanium, and hard materials.

Installation Notes

Installation is performed by qualified machinists. Secure the shank fully into a collet or end mill holder and torque the retention system according to the machine tool manufacturer specifications before spindle engagement. Confirm workpiece fixturing is rigid before initiating the cut, as keyseat operations produce lateral cutting forces. Follow all machine guarding and PPE requirements per shop safety standards.
