Harvey Tool 73118-C3 Square End Mill 3mm 4 Flute Altin

Product Description

The HARVEY TOOL 73118-C3 is a solid carbide square end mill designed for precision milling in a wide range of materials. With a 3 mm (0.1180 inch) cutting diameter and 4 flutes, this single-end mill delivers clean, accurate cuts in both ferrous and non-ferrous workpiece materials. The AlTiN coating provides elevated heat resistance and extended tool life in demanding cutting environments. A 30-degree helix angle promotes efficient chip evacuation and smooth cutting action. This tool is installed and operated by machinists, CNC programmers, and tool-and-die professionals working in job shops, production facilities, and maintenance environments.

The 73118-C3 is suited for slotting, profiling, and peripheral milling operations on machining centers and CNC milling machines. The 9 mm (0.354 inch) length of cut supports medium-depth passes while the 1/8 inch shank diameter fits standard collets and end mill holders. Right-hand cutting and right-hand flute direction are standard configurations for conventional CNC mill setups. This tool is appropriate for applications requiring tight tolerances and consistent surface finish.

Key Features

• Solid carbide construction for rigidity and wear resistance
• AlTiN coating for heat resistance and extended tool life in hard materials
• 4-flute geometry for improved surface finish and feed rate capability
• 30-degree right-hand helix for efficient chip evacuation
• Center-cutting design allows plunge entry into the workpiece
• 1.5 inch overall length fits standard toolholders without extended reach

Compatibility

Designed for use in CNC machining centers and manual mills accepting a 1/8 inch shank diameter. Fits standard ER collets and end mill holders sized for 0.125 inch shank tooling.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and the machine is in a safe state before loading or unloading tooling. Seat the shank fully in the collet or holder to the recommended engagement depth per the toolholder manufacturer. Verify runout with a dial indicator before beginning production cuts to protect both the tool and the workpiece.
