Accupro 12179021 Square End Mill 0.5in 4 Flute Carbide

Product Description

The ACCUPRO 12179021 is a solid carbide square end mill designed for high-performance milling in demanding production environments. With a 0.5 inch cutting diameter and four spiral flutes ground to a 40-degree helix angle, this tool delivers efficient chip evacuation and smooth surface finishes in ferrous and non-ferrous materials. The nACRo coating improves heat resistance and wear life in dry or near-dry cutting conditions. Centercutting geometry allows plunge entry directly into the workpiece. This is a right-hand cut, right-hand flute configuration in a stub-length format, making it a common choice for machinists and tool-and-die shops running CNC mills or manual knee mills.

This end mill suits general-purpose milling operations including slotting, profiling, and peripheral cuts where a short, rigid tool is preferred. The stub length reduces deflection in tight setups or shallow-depth applications. It is appropriate for use in production machining, job-shop work, and toolroom operations across ferrous and non-ferrous workpiece materials. No extended-reach or chipbreaker geometry is present, keeping the design straightforward for standard milling tasks.

Key Features

• Solid carbide micrograin substrate for extended tool life and edge retention
• nACRo coating for improved wear resistance and thermal stability
• 40-degree spiral helix promotes smooth cutting action and chip flow
• Centercutting design allows direct plunge milling
• Right-hand cut and right-hand flute for standard CNC and manual mill spindles
• Stub length format reduces deflection in shallow-depth applications

Compatibility

Designed as an OEM-style replacement or direct-fit cutting tool for standard 0.5 inch collet, shrink-fit, or set-screw tool holders used on CNC machining centers and manual mills.

Installation Notes

Installation should be performed by a qualified machinist or toolroom professional. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing tooling. Seat the shank to the full recommended engagement depth in the holder to minimize runout and prevent pullout during cutting. Verify tool holding torque specifications per the tool holder manufacturer guidelines before commencing the cut.
