Harvey Tool 31908-C3 Square End Mill 1/8 in 3 Flute Altin

Product Description

The HARVEY TOOL 31908-C3 is a solid carbide square end mill designed for precision material removal in milling operations. With a 1/8 inch cutting diameter and a 5/8 inch length of cut, this tool suits tight-tolerance slot milling, profiling, and peripheral cutting. The 3-flute geometry balances chip evacuation with surface finish quality. An AlTiN coating provides thermal resistance and wear protection, extending tool life in ferrous and high-hardness materials. The 30-degree helix angle promotes smooth cutting action and reduces chatter. This end mill is a single-end, right-hand cutting and right-hand flute design. It is installed and operated by machinists and CNC programmers working in job shops, tool rooms, and precision manufacturing environments.

This end mill is suited for milling operations on steel, stainless steel, cast iron, and other ferrous alloys where heat and abrasion resistance are priorities. The AlTiN coating makes it a strong choice for dry or near-dry machining environments. The 1/8 inch shank diameter matches directly to collets and tool holders of the same bore size, making it compatible with standard CNC machining centers and manual mills equipped with ER collet systems or precision end mill holders. Its compact geometry suits work on small features, tight cavities, and detail profiles.

Key Features

• Solid carbide construction for rigidity and wear resistance in demanding materials
• AlTiN coating enhances thermal resistance and extends tool life in ferrous applications
• 3-flute design balances chip clearance with improved finish quality
• 30-degree helix angle reduces cutting forces and chatter
• Centercutting capability allows plunge entry into workpiece
• Right-hand cut and right-hand flute orientation for standard CNC spindle direction

Compatibility

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

Installation Notes

Installation is performed by machinists or CNC setup personnel. Ensure the machine spindle is fully stopped and locked before loading or unloading the tool. Seat the shank fully within the collet or tool holder to the recommended engagement depth and torque the retention mechanism to the tool holder specification. Verify runout with a dial indicator before production cuts, as excessive runout accelerates wear on small-diameter carbide tooling.
