Accupro 12180411 Square End Mill 1/8 in 4 Flute Solid Carbide

Product Description

The ACCUPRO 12180411 is a solid carbide square end mill designed for precision milling operations in metal, alloy, and composite materials. Built from micrograin carbide with an AlTiN (aluminum titanium nitride) finish, this tool delivers excellent heat resistance and wear life in demanding cutting environments. It features a 0.125-inch cutting diameter, a 0.500-inch length of cut, and a 40-degree helix angle with spiral fluting. The centercutting geometry allows for plunge entry. This end mill is installed and operated by machinists and CNC programmers working in job shops, manufacturing facilities, and toolroom environments.

This end mill suits applications in ferrous metals, hardened steels, and high-temperature alloys where a tight-tolerance, small-diameter tool is required. The 4-flute configuration balances chip evacuation with surface finish quality. The right-hand cut and right-hand flute direction make it compatible with standard CNC machining centers and manual mills. The 1.500-inch overall length and 0.125-inch shank diameter fit standard ER collets and end mill holders used across vertical and horizontal milling platforms.

Key Features

• Solid micrograin carbide construction for rigidity and wear resistance in hard materials
• AlTiN finish provides thermal protection and extends tool life at elevated cutting speeds
• 40-degree helix angle promotes smooth chip flow and reduces cutting forces
• Centercutting design allows direct plunge milling without a pre-drilled hole
• 4-flute spiral geometry supports improved surface finish on ferrous and alloy workpieces
• Right-hand cut and right-hand flute direction for standard spindle operation

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide square end mill for standard 0.125-inch ER collet chucks and end mill holders on CNC machining centers and manual knee mills.

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, locked-out state before changing tooling. Seat the shank fully into the collet or holder and torque the retention nut to the tool holder manufacturer's specification. Verify runout with a dial indicator before initiating a cutting program, as even minor runout will reduce tool life on small-diameter end mills.
