Accupro 12181260 Square End Mill 1/8 in 2 Flute Solid Carbide

Product Description

The ACCUPRO 12181260 is a solid carbide square end mill designed for precision milling in ferrous and non-ferrous materials. With a 0.125-inch mill diameter, a 0.500-inch length of cut, and a 40-degree helix angle, this tool delivers clean side and slot milling performance in tight-tolerance applications. The TiCN coating adds surface hardness and lubricity, extending tool life in abrasive or high-speed cutting conditions. The micrograin carbide substrate supports rigidity and edge retention at small diameters. It is used by machinists and tool-and-die professionals working on CNC mills and manual milling machines.

This end mill is suited for light to moderate material removal in steel, stainless, aluminum, and similar workpiece materials. Its centercutting geometry allows direct plunge entry, making it effective for slot milling, pocketing, and profiling operations. The regular-length configuration keeps deflection low at this diameter, which is important when holding tight tolerances on small features. It is a common selection for mold work, fixture making, and precision part production in job shop and production environments.

Key Features

• 0.125-inch mill diameter with micrograin solid carbide substrate for rigidity and edge retention
• TiCN finish increases surface hardness and reduces friction at the cutting edge
• 40-degree spiral flute helix promotes efficient chip evacuation and smooth cutting action
• Centercutting design allows direct plunge entry for slot and pocket milling
• Right-hand cut and right-hand flute orientation for standard CNC and manual mill spindles
• Mill diameter tolerance of +0.000 / -0.002 inches for consistent fit in close-tolerance work

Compatibility

Designed as a standard shank square end mill for use in collet chucks, end mill holders, and shrink-fit toolholders accepting a 0.125-inch shank diameter on CNC machining centers and manual knee mills.

Installation Notes

Installation should be performed by a qualified machinist following shop safety procedures. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Secure the shank to the full recommended engagement depth in the toolholder to minimize runout and prevent pull-out under cutting loads. Verify spindle direction is set to right-hand rotation before beginning the cut.
