Harvey Tool 43962 Woodruff Keyseat Cutter Solid Carbide

Product Description

The HARVEY TOOL 43962 is a solid carbide Woodruff keyseat cutter designed for milling keyseat slots in rotating shafts and mating components. It features a 0.25-inch cutting diameter and a 0.062-inch cutting width, producing precise, standardized Woodruff keyway profiles in a single pass. The straight-tooth configuration and solid carbide construction deliver consistent cutting performance across ferrous and non-ferrous workpiece materials. With a 2.5-inch overall length and a 0.25-inch shank diameter, this cutter mounts directly in standard end mill holders or collet chucks. It is intended for use by machinists and toolroom professionals working on precision shaft and keyway applications.

This cutter is suited for keyseat milling operations on steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and hard materials. Typical applications include shaft preparation in mechanical power transmission, pump and motor component machining, and general toolroom work where accurate keyseat dimensions are critical. The 6-tooth straight configuration is appropriate for both CNC machining centers and manual milling machines operating at appropriate spindle speeds for carbide tooling.

Key Features

• Solid carbide construction for rigidity and wear resistance across a wide range of workpiece materials
• 0.25-inch cutting diameter and 0.062-inch cutting width for standard Woodruff keyseat profiles
• 6 straight teeth for consistent chip formation and repeatable slot dimensions
• 0.125-inch neck diameter with 0.75-inch neck length provides clearance during deep-slot operations
• Bright/uncoated finish suitable for use with or without cutting fluid
• No Weldon flat on shank — seats in standard precision collets without flat-seat requirements

Compatibility

Designed as a direct-fit Woodruff keyseat cutter for use in standard 1/4-inch shank collet chucks and end mill holders on CNC machining centers and manual vertical milling machines. Compatible with steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and hard materials per workpiece material classifications P, M, K, N, S, and H.

Installation Notes

This cutter is installed and operated by qualified machinists. Secure the 0.25-inch shank in a clean, properly sized collet or end mill holder and torque to the holder manufacturer's specification before engaging the spindle. Ensure the machine spindle is fully stopped and locked out before changing or inspecting tooling. Select spindle speed and feed rate appropriate for solid carbide tooling in the specific workpiece material being cut — consult published carbide cutting data for Woodruff keyseat cutters.
