Accupro 12177089 Square End Mill 0.5in 4 Flute Carbide Altin

Product Description

The ACCUPRO 12177089 is a solid carbide square end mill designed for precision milling in demanding metalworking applications. Built from micrograin carbide and finished with an AlTiN (aluminum titanium nitride) coating, this tool handles hardened steels, stainless, and high-temp alloys with strong wear resistance. It runs a 40-degree helix spiral flute geometry, which promotes efficient chip evacuation and reduces cutting forces. With a 0.5 inch cutting diameter, 1 inch length of cut, and 0.5 inch shank, it fits standard milling chucks and collet holders. Licensed machinists, toolmakers, and CNC operators rely on this configuration for slotting, profiling, and pocketing operations.

This end mill is suited for milling centers, VMCs, and manual knee mills in both production and job-shop environments. The four-flute, right-hand cut and right-hand spiral configuration makes it a standard workhorse for ferrous and non-ferrous material removal. The centercutting design allows plunge milling in addition to peripheral cuts. The 3 inch overall length provides enough reach for moderate-depth setups without sacrificing rigidity. Typical applications include contour milling, side milling, and finish passes on steel, cast iron, and aluminum workpieces.

Key Features

• Solid micrograin carbide construction for extended tool life in hard materials
• AlTiN coating provides high heat resistance and low friction at elevated cutting speeds
• 40-degree helix spiral flute promotes smooth chip flow and reduces chatter
• Centercutting capability allows direct plunge entry into the workpiece
• Right-hand cut, right-hand flute orientation for standard CNC and manual mill setups
• Mill diameter tolerance of +0.001 / -0.000 inches ensures consistent fit and finish dimensions

Compatibility

Designed for use with standard 0.5 inch collets, milling chucks, and shrink-fit holders on CNC machining centers and manual milling machines accepting a 0.5 inch shank diameter.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Secure the shank to the full recommended grip depth in the tool holder and verify runout before cutting. Always ensure the spindle is fully stopped and the machine is in a safe state before changing tooling. Consult the machine tool manufacturer and cutting tool guidelines for appropriate speeds, feeds, and depth-of-cut parameters for the workpiece material.
