Accupro 12179062 Square End Mill 1/2 in 4 Flute Carbide

Product Description

The ACCUPRO 12179062 is a solid carbide square end mill designed for precision milling in demanding metal-cutting applications. With a 0.5 inch cutting diameter, a 1.5 inch length of cut, and a 40-degree helix angle, this tool delivers aggressive chip evacuation and clean edge geometry on ferrous and non-ferrous workpieces. The nACRo coating reduces friction and extends tool life at elevated cutting temperatures. Four spiral flutes and a right-hand cut with right-hand flute orientation make this a standard configuration suited to conventional and climb milling operations. Centercutting geometry allows plunge entry without a pilot hole.

This end mill is suited for machining shops, tool rooms, and production environments running CNC mills, VMCs, or manual knee mills. It handles slotting, profiling, and peripheral milling in materials such as alloy steel, stainless steel, cast iron, and hardened materials where a high-performance coating is required. Micrograin carbide substrate provides the rigidity and wear resistance needed for tight-tolerance work. The 0.5 inch shank fits standard ER, CAT, BT, and side-lock toolholders commonly used in trade and production machining.

Key Features

• Solid micrograin carbide construction for rigidity and extended tool life
• nACRo coating for high-temperature wear resistance and reduced friction
• 40-degree helix angle promotes efficient chip evacuation and smooth cutting action
• Centercutting design allows direct plunge milling without a pre-drilled hole
• Right-hand cut, right-hand flute — standard orientation for CNC and manual setups
• Tight shank tolerance of -0.0001 to -0.0004 inches ensures secure toolholder fit

Compatibility

Designed as a direct-fit replacement or standard selection for any toolholder accepting a 0.5 inch shank diameter, including ER collet chucks, side-lock holders, and shrink-fit systems common in CNC machining centers.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the spindle is fully stopped and the machine is in a safe state before inserting or removing the tool. Confirm the toolholder bore is clean and free of chips before seating the shank, and torque the retention mechanism to the toolholder manufacturer specification. Verify runout with a dial indicator before committing to a production cut.
