Harvey Tool 900331-C3 Woodruff Keyseat Cutter

Product Description

The HARVEY TOOL 900331-C3 is a solid carbide Woodruff keyseat cutter designed for milling keyseat slots in shafts and workpieces. It features a 0.1562 inch cutting diameter and a 0.031 inch cutting width, making it suited for precision keyway work where tight tolerances are required. The straight-tooth configuration provides clean, accurate cuts in a range of materials. With an AlTiN coating, it offers improved heat resistance and tool life in demanding cutting conditions. This cutter is installed via a 3/16 inch shank connection on a compatible milling machine or machining center.

This cutter is intended for use in precision machining applications where Woodruff-style keyseat slots are required. It is commonly used by machinists and toolmakers working on shafts, spindles, and similar components in job shop, production, and maintenance environments. The compact 0.1562 inch cut diameter makes it appropriate for small-scale keyway features where larger cutters cannot be applied.

Installation Notes

Installation is performed by qualified machinists on a vertical milling machine or machining center. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Secure the shank firmly in a compatible collet or tool holder rated for the 3/16 inch shank diameter. Follow the machine manufacturer feed and speed recommendations for carbide keyseat cutters to avoid tool deflection or breakage.
