Harvey Tool 73109-C3 Square End Mill 7/64 in 4 Flute Carbide

Product Description

The HARVEY TOOL 73109-C3 is a square end mill designed for precision milling in demanding machining environments. Built from solid carbide, this single-end tool features a 7/64 inch (0.109 inch) cutting diameter, a 0.327 inch length of cut, and a 1/8 inch shank diameter. The 30-degree helix angle promotes efficient chip evacuation and smooth cutting action. An AlTiN (aluminum titanium nitride) coating improves heat resistance and tool life at elevated cutting speeds. With four flutes and centercutting capability, it handles both slotting and plunge operations. CNC machinists and tool-and-die professionals install this end mill in vertical machining centers and CNC mills.

This end mill is suited for small-feature milling applications where tight tolerances and fine detail are required. The 7/64 inch diameter and 1-1/2 inch overall length make it a practical choice for slotting, profiling, and pocket milling in ferrous and non-ferrous materials. The right-hand cut and right-hand flute configuration is standard for conventional CNC spindle setups. Centercutting geometry allows direct plunge entry without a pre-drilled pilot hole, adding flexibility in complex toolpaths.

Key Features

• Solid carbide construction for rigidity and wear resistance in high-speed applications
• AlTiN coating provides thermal protection and extends tool life in abrasive or elevated-temperature cuts
• Four-flute design balances chip clearance and surface finish in slotting and profiling
• 30-degree helix angle promotes smooth cutting and effective chip evacuation
• Centercutting geometry enables direct plunge milling without a pilot hole
• Right-hand cut and right-hand flute configuration for standard CNC spindle compatibility

Compatibility

Designed as an OEM-style solid carbide square end mill compatible with 1/8 inch tool holders and collets in standard CNC machining centers and manual mills.

Installation Notes

Installation should be performed by a qualified CNC machinist or toolroom professional. Ensure the spindle is fully stopped and the machine is in a safe state before changing tooling. Secure the shank fully within the collet or tool holder to the manufacturers recommended engagement depth to prevent pullout. Verify runout with a dial indicator before beginning a production cut.
