Accupro 314818 Square End Mill 1/2 in 3 Flute Carbide Zrn

Product Description

The ACCUPRO 314818 is a 3-flute solid carbide square end mill designed for precision milling in ferrous and non-ferrous materials. It features a 1/2-inch cutting diameter, a 5/8-inch length of cut, and a 37-degree right-hand helix angle that promotes efficient chip evacuation and smooth cutting action. The tool is coated with zirconium nitride (ZrN), which adds surface hardness and wear resistance for extended tool life in demanding machining environments. Machined from micrograin carbide stock, it holds tight tolerances and is center-cutting capable, allowing plunge entry directly into the workpiece.

This end mill is suited for milling operations in machine shops, production environments, and toolroom applications. It is used in vertical and horizontal CNC machining centers as well as manual knee mills. The 1/2-inch shank diameter fits standard ER and shell mill collet systems. Typical applications include slotting, profiling, and peripheral milling in steel, alloy, stainless, and non-ferrous materials where a short-reach, rigid 3-flute geometry is preferred.

Key Features

• 1/2-inch cutting diameter with mill diameter tolerance of +0.000 / -0.005 inches
• 37-degree right-hand spiral helix for efficient chip flow and reduced cutting forces
• ZrN (zirconium nitride) coating for improved wear resistance and surface hardness
• Center-cutting geometry allows direct plunge milling without a pilot hole
• Micrograin solid carbide construction for rigidity and edge retention
• Single-end design with 3-inch overall length and 1/2-inch shank diameter

Compatibility

Designed as a standard-shank replacement end mill compatible with 1/2-inch collet chucks, ER collet systems, and end mill holders used on CNC machining centers and manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the machine spindle is fully stopped and locked out before inserting or removing the tool from the holder. Seat the shank to the recommended gauge depth for the collet or holder in use and torque the retention mechanism according to the toolholder manufacturer specifications. Inspect the cutting edges and coating for chips or wear before each use.
