Harvey Tool 802431-C3 Square End Mill 1/32 in 4 Flute Carbide

Product Description

The HARVEY TOOL 802431-C3 is a single-end square end mill designed for precision milling in tight-tolerance applications. Built from solid carbide, this tool features a 1/32-inch cutting diameter and a 4-flute geometry that supports efficient chip evacuation and smooth surface finishes. The AlTiN coating provides thermal resistance and extended tool life when cutting hardened steels, stainless alloys, and other demanding materials. At 1.5 inches overall length with a 1/8-inch shank, this micro end mill is suited for small-feature work where rigidity and dimensional accuracy are critical. Licensed machinists and CNC tooling specialists are the primary users.

This end mill is built for small-scale contouring, slotting, and profiling operations on CNC machining centers and manual mills. The 3/32-inch length of cut and extended reach design make it effective for accessing recessed features or narrow pockets. The right-hand cutting and right-hand flute direction are standard for conventional CNC setups. The 30-degree helix angle balances cutting force and chip flow across ferrous and non-ferrous materials. Applications include mold and die work, medical component machining, and aerospace part production where fine detail and close tolerances are required.

Key Features

• Solid carbide construction for rigidity and wear resistance in demanding cuts
• AlTiN coating for high-temperature performance and extended tool life
• 4-flute design promotes smooth finishes and efficient material removal
• 30-degree helix angle balances cutting forces and chip evacuation
• Center-cutting geometry allows plunge entry as well as peripheral milling
• Extended reach with 3/16-inch reach length for recessed feature access

Compatibility

Designed as a direct-fit tooling solution for CNC machining centers and manual mills accepting a 1/8-inch shank diameter collet or tool holder.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Use a properly sized collet or end mill holder rated for 1/8-inch shank diameter to maintain concentricity and minimize runout. At this micro diameter, excessive overhang or improper clamping force increases breakage risk — verify holder condition before use.
