Accupro 12179770 Square End Mill 1 in 3 Flute Carbide Zrn

Product Description

The ACCUPRO 12179770 is a solid carbide square end mill designed for high-performance milling in metalworking and machining applications. Built from micrograin carbide with a ZrN (zirconium nitride) finish, this end mill delivers extended tool life and improved wear resistance compared to uncoated alternatives. It features a 1 inch cutting diameter, a 3-3/8 inch length of cut, and a 6 inch overall length, placing it in the long-reach category. The 40-degree helix angle and three-flute spiral configuration promote efficient chip evacuation and smooth cutting action. Licensed machinists and CNC operators install this tool in machining centers and manual mills.

This end mill is suited for slotting, profiling, and peripheral milling operations across a range of ferrous and non-ferrous materials. The long length of cut supports deep-pocket milling and applications requiring extended reach beyond standard end mill configurations. The 1 inch shank diameter provides rigid coupling in standard ER or side-lock toolholders. It is appropriate for both production environments and job-shop work where consistent dimensional accuracy is required.

Key Features

• Solid micrograin carbide construction for rigidity and wear resistance
• ZrN finish reduces friction and extends tool life in abrasive materials
• 40-degree helix angle promotes efficient chip evacuation and smooth cuts
• Centercutting design allows plunge entry into the workpiece
• Right-hand cut and right-hand flute spiral configuration
• Long length-of-cut category supports deep-pocket and extended-reach milling

Compatibility

Designed for use in CNC machining centers, vertical mills, and manual knee mills accepting a 1 inch straight shank via ER collet, Weldon side-lock, or hydraulic toolholder systems.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and the machine is locked out before changing tooling. Seat the shank to the minimum insertion depth recommended for the toolholder style in use to maximize rigidity and minimize runout. Verify tool runout with a dial indicator before beginning cuts, particularly for long-reach applications where deflection is a greater concern.
