Accupro 313072 Square End Mill 1/4 in 2 Flute Solid Carbide

Product Description

The ACCUPRO 313072 is a solid carbide square end mill designed for precision material removal in milling operations. The 1/4 inch cutting diameter pairs with a 1-1/4 inch length of cut and a 3 inch overall length, making this a long-reach configuration suitable for deeper slot and profile work. The 45-degree helix angle promotes efficient chip evacuation and reduces cutting forces. A ZrN (zirconium nitride) coating adds surface hardness and heat resistance, extending tool life in ferrous and non-ferrous applications. Machinists and tool-and-die professionals typically use this end mill in CNC machining centers and manual mills.

This end mill is suited for slot milling, profiling, and peripheral cutting in a range of materials including aluminum, brass, steel, and similar machinable metals. The micrograin carbide substrate supports tight tolerances and consistent edge integrity across production runs. The right-hand cutting and right-hand spiral flute direction are standard for conventional CNC setups. The single-end, centercutting design allows plunge entry, adding flexibility for complex tool paths.

Key Features

• Solid micrograin carbide construction for rigidity and wear resistance
• ZrN coating improves heat resistance and extends tool life
• 45-degree helix angle promotes aggressive chip evacuation
• Centercutting geometry allows plunge milling entry
• Right-hand cut and right-hand spiral flute direction for standard CNC compatibility
• Long length-of-cut configuration supports deeper reach applications

Compatibility

Designed as an OEM-style solid carbide square end mill for use in standard 1/4 inch collets and end mill holders on CNC machining centers and manual milling machines.

Installation Notes

Installation and tool changes should be performed by qualified machinists with the machine powered down and spindle at a complete stop. Secure the 1/4 inch shank in a properly sized collet or end mill holder, tightening to the tool holder manufacturer's specifications. Inspect the cutting edges and coating for chips or damage before each use. Follow shop safety protocols and machine guard requirements during operation.
