Harvey Tool 68478 Woodruff Keyseat Cutter Solid Carbide

Product Description

The HARVEY TOOL 68478 is a solid carbide Woodruff keyseat cutter designed for milling keyseats and slots in rotating shafts and mechanical components. It features a 0.375-inch cutting diameter and a 0.1562-inch cutting width, with a straight-tooth configuration across 6 flutes. The 3/8-inch shank diameter and 2.5-inch overall length make it well-suited for standard milling setups. The bright, uncoated carbide construction delivers rigidity and edge retention when cutting steel, stainless steel, and cast iron. Machinists and tool-and-die professionals install this cutter on vertical milling machines and machining centers for keyseat work that demands tight dimensional accuracy.

This cutter is used in applications requiring precise keyway profiles in ferrous and non-ferrous workpieces. Primary target materials include steel, stainless steel, and cast iron. Secondary applications cover non-ferrous metals, superalloys, titanium, and hard materials. The 0.1870-inch neck diameter and 0.5630-inch neck length provide clearance for keyseat cuts at controlled depth without excessive tool deflection. Typical use is in job shops, maintenance and repair operations, and production machining environments where standard Woodruff keyseat profiles are required.

Key Features

• Solid carbide construction for rigidity and edge retention in ferrous materials
• 0.375-inch cutting diameter with 0.1562-inch cutting width for standard Woodruff keyseat profiles
• 6-tooth straight configuration for clean, consistent slot geometry
• 0.1870-inch neck diameter provides clearance relief below the cutting head
• Bright, uncoated finish suitable for use with cutting fluids or dry cutting
• 3/8-inch shank diameter compatible with standard collet and end mill holder setups

Compatibility

Designed for use in vertical milling machines and CNC machining centers accepting a 3/8-inch shank. Suitable for cutting keyseats in steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and hard materials.

Installation Notes

Install in a collet or end mill holder rated for the 3/8-inch shank diameter and confirm runout before cutting. Power down and lock out the spindle before changing or inspecting the cutter. Follow the machine manufacturer and tooling specifications for spindle speed and feed rate based on workpiece material. Handle solid carbide tooling carefully to avoid chipping the cutting edges during setup.
