Harvey Tool 972250-C3 Square End Mill 0.05in 4 Flute Altin

Product Description

The HARVEY TOOL 972250-C3 is a solid carbide square end mill designed for high-precision milling in demanding machining environments. With a 0.05-inch cutting diameter and a 0.15-inch length of cut, this tool is built for fine-detail work in tight geometries. The 4-flute, right-hand cutting configuration paired with a 30-degree helix angle promotes efficient chip evacuation and smooth surface finishes. An AlTiN coating adds hardness and heat resistance, making this end mill well-suited for cutting ferrous metals, hardened steels, and high-temp alloys. Extended reach geometry and centercutting capability expand its range of applications. Installed and run by machinists and toolroom professionals on CNC milling machines and machining centers.

This end mill is intended for precision milling operations where small diameters, tight tolerances, and fine feature detail are required. Typical applications include slotting, profiling, and contouring in tool steels, stainless steels, and similar hard materials. The 0.125-inch shank diameter fits standard collets and tool holders on CNC vertical mills and machining centers. The 1.5-inch overall length provides clearance for a variety of workpiece configurations. Extended reach length of 0.4 inches accommodates deeper cavity work without sacrificing rigidity at this diameter.

Key Features

• 0.05-inch cutting diameter for fine-detail and small-feature milling
• AlTiN coating for elevated heat resistance and tool life in ferrous and hard materials
• 4 right-hand flutes with 30-degree helix for efficient chip evacuation
• Centercutting design allows plunge entry
• Extended reach configuration with 0.4-inch reach length
• Solid carbide construction for rigidity and wear resistance at small diameters

Compatibility

Designed as an OEM-style solid carbide square end mill for use in standard 1/8-inch collets and compatible tool holders on CNC milling machines and machining centers.

Installation Notes

Installation should be performed by a qualified machinist or toolroom professional. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing tooling. Secure the shank fully within the collet or tool holder to the manufacturer-specified engagement depth to prevent pullout at operating speeds. Verify runout with a dial indicator before beginning production cuts, especially critical at this small diameter.
