Accupro 12179033 Square End Mill 1/4 in 4 Flute Carbide

Product Description

The ACCUPRO 12179033 is a 4-flute solid carbide square end mill designed for precise milling operations in ferrous and non-ferrous materials. It features a micrograin carbide substrate for improved wear resistance and edge retention, paired with an nACRo coating that reduces friction and extends tool life in demanding cuts. With a 1/4 inch cutting diameter, 1-1/8 inch length of cut, and 3 inch overall length, this end mill suits slotting, profiling, and peripheral milling in both manual and CNC machine tool applications. It is installed and changed by machinists and toolroom technicians working in job shops, production environments, and maintenance facilities.

This end mill is suited for use in vertical machining centers, CNC mills, and manual knee mills where a 1/4 inch shank tool holder or collet is used. The 40-degree helix angle promotes efficient chip evacuation and smooth cutting action, making it a practical choice for steels, stainless alloys, and similar materials where the nACRo coating provides a performance advantage. The centercutting geometry allows plunge entry, adding versatility in pocketing and ramping operations.

Key Features

• Solid micrograin carbide construction for hardness and wear resistance
• nACRo coating reduces heat and friction during cutting
• 4-flute spiral design with 40-degree helix for effective chip evacuation
• Centercutting geometry allows direct plunge entry into workpiece
• Right-hand cut and right-hand flute configuration for standard spindle use
• Mill diameter tolerance of plus 0.000 / minus 0.002 inches for consistent fitment

Compatibility

Designed as an OEM-style replacement or direct-fit cutting tool for machine tool setups requiring a 1/4 inch shank square end mill with a 3 inch overall length.

Installation Notes

Installation is performed by machinists or toolroom technicians. The tool should be secured in a 1/4 inch collet or end mill holder with the shank fully seated to the specified engagement depth before tightening. Verify spindle is fully stopped and machine is in a locked or e-stop state before changing tooling. Do not exceed the recommended speeds and feeds for the workpiece material and coating type as specified in the tooling manufacturer guidelines.
