Harvey Tool 31875-C3 Square End Mill 0.075 in 3 Flute Carbide

Product Description

The HARVEY TOOL 31875-C3 is a miniature square end mill designed for precision material removal in tight-tolerance machining applications. Built from solid carbide, this single-end mill features a 0.075 inch cutting diameter, a 0.375 inch length of cut, and a 30-degree helix angle. The AlTiN coating improves heat resistance and tool life when cutting ferrous and abrasive materials. With three flutes and a right-hand cut and right-hand flute configuration, this tool delivers efficient chip evacuation at small diameters. It is centercutting, allowing plunge entry, and is suited for use in CNC machining centers and high-speed milling equipment.

This end mill is built for machining steel, stainless steel, cast iron, aluminum and non-ferrous metals, and CFRP materials. Its miniature 0.075 inch diameter and long-flute geometry make it well suited for slotting, profiling, and pocketing operations in small-feature workpieces. Typical applications include mold and die work, medical component machining, and aerospace part production where fine detail and small-radius features are required. The 0.125 inch shank diameter fits standard collets and tool holders common in precision machining setups.

Key Features

• Solid carbide construction for rigidity and wear resistance at miniature diameters
• AlTiN coating provides elevated heat resistance for extended tool life in ferrous materials
• 3-flute design balances chip evacuation and cutting efficiency at small diameters
• 30-degree helix angle reduces cutting forces and supports smooth finishes
• Centercutting geometry allows direct plunge entry into workpiece material
• Long-flute series with 0.375 inch length of cut for deeper feature access

Compatibility

Rated for use in steel, stainless steel, cast iron, aluminum and non-ferrous metals, and CFRP materials. Part of the Harvey Tool Miniature End Mills - Square - Long Flute series. The 0.125 inch shank diameter is compatible with standard precision collet systems.

Installation Notes

Installation and use should be performed by a qualified machinist familiar with CNC milling operations. Secure the shank fully in a precision collet or tool holder before spindle engagement and verify runout before cutting. Follow the machine tool manufacturer guidelines for speeds, feeds, and depth of cut for the workpiece material. Inspect the cutting edges before each use; carbide tools are brittle and should not be used if chipping is present.
