Harvey Tool 43962-C3 Woodruff Keyseat Cutter 0.25in Altin

Product Description

The HARVEY TOOL 43962-C3 is a solid carbide Woodruff keyseat cutter designed for milling semicircular keyseats in shafts and mating components. It features a 0.25-inch cut diameter and a 0.062-inch cut width, with a straight tooth configuration across 6 flutes. The AlTiN coating provides elevated heat resistance and extended tool life when cutting ferrous and difficult materials. The 1/4-inch shank diameter and 2.5-inch overall length make it compatible with standard collet chucks and tool holders found in most milling setups. This cutter is intended for use by machinists and tool-and-die professionals working in precision manufacturing environments.

The 43962-C3 is suited for keyseat operations in steel, stainless steel, and cast iron as primary workpiece materials. It also performs in non-ferrous metals, superalloys, titanium, and hard materials, making it a versatile choice across a range of production and job-shop applications. The straight tooth geometry is well matched to conventional keyseat cuts where chip load consistency and clean sidewall finish are priorities. A neck diameter of 0.125 inches and neck length of 0.75 inches allow for clearance in recessed or deeper keyseat profiles.

Key Features

• Solid carbide construction for rigidity and wear resistance in demanding materials
• AlTiN coating for thermal protection and longer tool life in ferrous and hard workpiece materials
• 0.25-inch cut diameter with 0.062-inch cut width for standard Woodruff keyseat profiles
• 6 straight teeth for consistent chip load and clean keyseat walls
• 0.125-inch neck diameter with 0.75-inch neck length provides clearance in recessed applications
• 1/4-inch shank diameter fits standard collet chucks and end mill holders

Compatibility

Designed for use in CNC and manual milling machines with 1/4-inch collet or end mill holder tooling. Intended for keyseat milling in steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and hard materials.

Installation Notes

Installation and operation should be performed by a qualified machinist familiar with milling cutter tooling and safe machine setup practices. Secure the shank fully in a properly sized collet or end mill holder before operation and verify runout before cutting. Power down the spindle completely before changing or inspecting the cutter. Do not exceed the cutter manufacturer recommended feed and speed parameters for the specific workpiece material and machine configuration.
