Harvey Tool 790793-C6 Square End Mill 3/32 in 4 Flute Carbide

Product Description

The HARVEY TOOL 790793-C6 is a solid carbide square end mill designed for precision milling in ferrous and non-ferrous materials. It features a 3/32 inch (0.093 inch) cutting diameter, a 3/8 inch length of cut, and four flutes with a variable helix geometry that reduces chatter and harmonics during aggressive cuts. The AlTiN Nano coating extends tool life by providing high-temperature oxidation resistance and a hard, low-friction surface. This end mill is single-end, right-hand cutting, right-hand flute, and centercutting, making it capable of plunge entries. It is installed and used by machinists and CNC operators in production and job-shop environments.

This end mill is suited for tight-tolerance milling applications in materials such as hardened steels, stainless, titanium, and other difficult-to-machine alloys where heat and tool deflection are primary concerns. The 1/8 inch shank diameter fits standard ER collets and end mill holders. With a 2-1/2 inch overall length and a compact cutting length, it is well-suited for shallow-profile features, slots, and side-milling operations where rigidity and runout control are critical. Typical applications include finishing passes and moderate material removal in precision machined components.

Key Features

• 3/32 inch cutting diameter (0.093 inch) with 3/8 inch length of cut
• Variable helix flute geometry reduces chatter and improves surface finish
• AlTiN Nano coating for high-temperature wear resistance and extended tool life
• Four flutes, right-hand cut, right-hand helix, centercutting capable
• Solid carbide construction for rigidity and dimensional stability
• 1/8 inch shank diameter for compatibility with standard toolholding systems

Compatibility

Designed for use in CNC machining centers and manual mills equipped with standard ER collet chucks or end mill holders accepting a 1/8 inch shank diameter.

Installation Notes

Installation is performed by machinists or CNC setup technicians. Ensure the spindle is fully stopped and the machine is in a safe state before loading or unloading the tool. Seat the shank fully and evenly in the collet or holder to the recommended grip length before torquing the nut. Verify runout at the cutting diameter with a dial indicator before beginning production cuts to avoid premature tool failure or part rejection.
