Harvey Tool 984560-C3 Woodruff Keyseat Cutter 0.75 in

Product Description

The HARVEY TOOL 984560-C3 is a Woodruff keyseat cutter designed for milling keyseats and slots in rotating shafts and machined components. Built from brazed solid carbide with an AlTiN coating, this cutter delivers hard-material performance and extended tool life in demanding cutting environments. It features a 0.75 inch cut diameter, a 0.187 inch cut width, and a 3/8 inch shank diameter with a Weldon flat for secure toolholder engagement. The straight tooth configuration and 10-tooth count produce clean, consistent slot geometry. Machinists and tool-and-die professionals install this cutter in CNC machining centers and manual knee mills.

This keyseat cutter is suited for producing Woodruff keyseats in shaft work on precision mechanical assemblies. Typical applications include automotive drivetrain components, industrial shaft-and-hub assemblies, and custom fixturing where a standardized Woodruff key slot is required. The AlTiN finish provides elevated heat resistance, making it a practical choice when cutting alloy steels, hardened steels, and other ferrous materials at elevated spindle speeds. The 3-3/16 inch overall length provides adequate reach for most standard keyseat depth requirements.

Key Features

• Brazed solid carbide construction for rigidity and wear resistance in hard materials
• AlTiN coating provides heat and oxidation resistance during high-speed cutting
• 0.75 inch cut diameter with 0.187 inch cut width for standard Woodruff keyseat profiles
• 10 straight teeth deliver clean slot walls and predictable chip load per tooth
• Weldon flat on 3/8 inch shank prevents axial pullout in side-load cutting operations
• 3-3/16 inch overall length supports reach into standard shaft configurations

Compatibility

Designed as an OEM-style keyseat cutter compatible with standard 3/8 inch Weldon-flat toolholders used in CNC machining centers and manual milling machines.

Installation Notes

Installation is performed by qualified machinists. Secure the 3/8 inch shank into a Weldon-flat endmill holder and torque the set screw against the flat per the toolholder manufacturer specification before cutting. Power down and lock out the spindle before changing or inspecting the cutter. Inspect the brazed joint and cutting edges for chipping or delamination prior to each use — do not run a cutter with a compromised braze bond.
