Accupro 12182225 Square End Mill 1/2 in 3 Flute Carbide

Product Description

The ACCUPRO 12182225 is a solid carbide square end mill designed for precision milling operations in metal cutting environments. With a 0.500 inch cutting diameter, a 2.000 inch length of cut, and a 3-flute spiral configuration at a 40-degree helix angle, this tool delivers efficient chip evacuation and smooth surface finishes in demanding applications. The micrograin carbide substrate provides edge retention under high cutting forces. An AlTiN coating adds thermal resistance and reduces built-up edge, extending tool life in ferrous and high-temperature alloy cuts. This is a single-end, right-hand cut, right-hand flute tool with centercutting capability, allowing plunge entry directly into the workpiece.

This end mill suits machining centers and CNC mills in job shops, tool rooms, and production environments cutting steel, stainless steel, cast iron, and similar materials. The long-length geometry — 4.000 inch overall length with a 2.000 inch length of cut — provides reach for deeper pockets and stepped features where standard-length tools cannot reach. The 0.500 inch shank diameter fits standard ER, Weldon, and shrink-fit toolholders common to most machining setups.

Key Features

• Solid micrograin carbide construction for high hardness and wear resistance
• AlTiN coating for thermal barrier performance in dry and semi-dry cutting
• 40-degree helix angle promotes efficient chip flow and reduced cutting forces
• Centercutting design allows plunge milling without a pre-drilled entry hole
• Right-hand cut and right-hand flute — compatible with standard spindle rotation
• Long-length classification with 2.000 inch LOC for deep pocket and step milling

Compatibility

Designed as an OEM-style solid carbide square end mill for use in standard 1/2 inch bore toolholders on CNC machining centers and manual knee mills.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator following shop safety protocols. Ensure the spindle is fully stopped and the machine is in an e-stop or lockout state before changing tooling. Insert the shank to the full recommended engagement depth in the toolholder — avoid holding by the fluted portion. Verify runout with a dial indicator after clamping and before initiating a cut to prevent premature tool failure.
