Harvey Tool 988920 Woodruff Keyseat Cutter Solid Carbide

Product Description

The HARVEY TOOL 988920 is a solid carbide Woodruff keyseat cutter designed for milling keyseat slots in shafts and mating components. It features a 0.5-inch cut diameter, a narrow 0.047-inch cutting width, and a 1/2-inch straight shank. With 6 straight teeth and a bright uncoated finish, this cutter is built for accurate, repeatable keyseat profiles in steel, stainless steel, and cast iron. Machinists and toolroom technicians use it for precision slotting operations on manual mills and CNC machining centers where tight tolerances on keyway width and depth are required.

This cutter is suited for ferrous and non-ferrous applications including steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and hard materials. Its 0.25-inch neck diameter and 0.75-inch neck length provide clearance for reaching keyseat locations recessed from the end of a shaft without interference from the shank body. The 3-inch overall length supports reach into deeper workpiece setups common in shaft and hub assemblies.

Key Features

• Solid carbide construction for rigidity and wear resistance in ferrous and hard materials
• 0.5-inch cut diameter with 0.047-inch cutting width for narrow, precise keyseat profiles
• 6 straight teeth for clean slot geometry in steel, stainless steel, and cast iron
• 0.25-inch neck diameter with 0.75-inch neck length for clearance in recessed keyseat locations
• Bright uncoated finish suitable for use with cutting fluid across a range of workpiece materials
• 1/2-inch shank diameter for standard ER or side-lock toolholding systems

Compatibility

Designed for use on vertical milling machines and CNC machining centers accepting a 1/2-inch straight shank. Primary workpiece materials include steel, stainless steel, and cast iron. Secondary workpiece materials include non-ferrous metals, superalloys, titanium, and hard materials.

Installation Notes

Installation requires a collet chuck, side-lock holder, or Weldon-style toolholder accepting a 1/2-inch shank. Confirm the holder is clean and undamaged before seating the cutter. Secure the workpiece rigidly in a vise or fixture before engaging the cut, and verify spindle speed and feed rate against the cutter manufacturer recommendations for the workpiece material. Do not exceed the rated cutting width in a single pass without confirming the setup can handle the resulting radial load.
