Accupro 12178765 Square End Mill 0.5in 2 Flute Solid Carbide

Product Description

The ACCUPRO 12178765 is a solid carbide square end mill designed for precision milling operations in metal, composite, and hard material applications. With a 0.5 inch cutting diameter, a 1 inch length of cut, and a 3 inch overall length, this tool fits standard 0.5 inch shank toolholders and collets. The two-flute geometry and 40-degree helix angle promote efficient chip evacuation and reduced cutting forces. The nACRo coating provides enhanced wear resistance and thermal stability, extending tool life in demanding cuts. Micrograin carbide construction delivers the rigidity and edge retention required for finishing and semi-finishing passes.

This end mill is suited for use in CNC machining centers, manual knee mills, and multi-axis equipment where a standard-reach, short-flute tool is appropriate. The centercutting design allows plunge entry, making it versatile for slot milling, pocket milling, and contour work. Right-hand cut and right-hand flute orientation match the most common spindle configurations in job shops and production environments. Machinists, tool and die makers, and CNC operators working in ferrous and non-ferrous materials will find this a practical general-purpose tool for regular-length applications.

Key Features

• Solid micrograin carbide construction for rigidity and edge retention
• nACRo finish coating for improved wear resistance and heat tolerance
• 40-degree spiral helix angle promotes chip evacuation and smooth cutting action
• Centercutting geometry allows direct plunge entry into workpiece
• Right-hand cut and right-hand flute for standard CNC and manual mill spindles
• Matched shank and cutting diameter at 0.5 inches for straightforward toolholder setup

Compatibility

Designed for use with standard 0.5 inch ID collets, end mill holders, and shrink-fit toolholders commonly found on CNC machining centers and manual milling machines.

Installation Notes

Installation is performed by a machinist or CNC operator. Secure the shank fully within the toolholder to the recommended engagement depth before tightening. Verify runout at the cutting diameter before beginning a cut, as excessive runout accelerates edge wear on carbide tooling. Follow the machine tool manufacturer guidelines for spindle speed and feed rate when setting up this end mill for a new application.
