Harvey Tool 890670 Woodruff Keyseat Cutter 0.875 in 12T Carbide

Product Description

The HARVEY TOOL 890670 is a brazed solid carbide Woodruff keyseat cutter designed for milling keyseat slots in shafts and components across a range of metalworking applications. With a 0.875-inch cutting diameter and a 0.25-inch cutting width, this straight-tooth cutter produces precise keyseat profiles in a single pass. The 3/8-inch shank diameter and 3.25-inch overall length make it compatible with standard milling chucks and collet holders. Solid carbide construction provides the rigidity and wear resistance needed when working in steel, stainless steel, and cast iron. Twelve straight teeth deliver clean, consistent slot geometry. This cutter is installed and operated by machinists and toolroom technicians on vertical milling machines and machining centers.

The 890670 is suited for keyseat milling operations in ferrous metals including steel, stainless steel, and cast iron, as well as secondary applications in non-ferrous metals, superalloys, titanium, and hard materials. It is a common choice for shaft work in precision manufacturing, maintenance machining, and toolroom environments where consistent slot width and concentricity are required. The bright, uncoated finish makes it straightforward to inspect for wear after use.

Key Features

• Brazed solid carbide construction for rigidity and extended tool life in ferrous materials
• 0.875-inch cutting diameter with 0.25-inch cutting width for standard keyseat profiles
• 12 straight teeth for clean slot geometry and consistent chip load
• 3/8-inch shank diameter fits standard milling collets and chucks without adapters
• Bright, uncoated finish allows easy visual inspection of cutting edges
• Rated for steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and hard materials

Compatibility

Designed as a direct-fit keyseat cutter for use in standard vertical milling machines and machining centers accepting a 3/8-inch shank. Primary workpiece materials include steel, stainless steel, and cast iron. Secondary workpiece materials include non-ferrous metal, superalloys, titanium, and hard materials.

Installation Notes

Installation is performed by qualified machinists. Secure the 3/8-inch shank in a properly sized collet or end mill holder and verify runout before cutting. Ensure the spindle and workpiece are fully stopped before tool changes. Follow machine manufacturer guidelines for feed rate and depth of cut when working with solid carbide tooling to avoid edge chipping.
