Harvey Tool 73076-C3 Square End Mill 0.076in 4 Flute Altin

Product Description

The HARVEY TOOL 73076-C3 is a solid carbide square end mill designed for precision milling in demanding machining environments. With a 0.076-inch cutting diameter and a 0.228-inch length of cut, this tool handles slotting, profiling, and finishing passes in tight tolerances. The AlTiN coating extends tool life in abrasive and high-temperature applications. Four flutes and a 30-degree helix angle promote efficient chip evacuation and a smooth surface finish. Overall length is 1.5 inches with a 0.125-inch shank diameter. This end mill is installed and operated by machinists and CNC programmers working in job shops, tool rooms, and production environments.

This end mill is suited for small-feature milling in ferrous and non-ferrous materials where tight tolerances and fine surface finish are required. The centercutting geometry allows for plunge entry, giving operators flexibility in toolpath programming. The right-hand cut and right-hand flute direction are standard for conventional CNC milling setups. It is commonly used on vertical machining centers and CNC mills handling detailed work in die-mold, medical, and aerospace component production.

Key Features

• 0.076-inch cutting diameter for small-feature and detail milling
• AlTiN coating for extended tool life in high-temperature and abrasive conditions
• 4-flute geometry with 30-degree helix for efficient chip evacuation and improved finish
• Centercutting design allows plunge entry and versatile toolpath options
• Solid carbide construction for rigidity and dimensional stability
• Right-hand cut and right-hand flute direction for standard CNC compatibility

Compatibility

Designed as a direct-fit replacement or standard tooling selection for CNC mills and vertical machining centers accepting a 0.125-inch shank diameter collet or tool holder.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and the machine is in an e-stop or powered-down state before changing tooling. Seat the shank fully in a collet or end mill holder and torque the retention nut according to the tool holder manufacturer specifications. Confirm runout with a dial indicator before initiating a cutting program, particularly at small diameters where runout has an outsized effect on tool life and part quality.
