Accupro 14788584 Square End Mill 5/16 Inch 4 Flute Carbide

Product Description

The ACCUPRO 14788584 is a solid carbide square end mill designed for precision material removal in milling applications. With 4 helical flutes and a centercutting design, this tool handles both plunge cuts and standard peripheral milling. The 5/16 inch (0.3130 inch) mill diameter and matching cylindrical shank diameter make it a direct-fit option for standard collet and tool holder setups. A 1-1/2 inch length of cut provides ample depth for slotting, profiling, and pocketing operations. Solid carbide construction delivers the rigidity and wear resistance required for cutting ferrous and non-ferrous workpiece materials at elevated feeds and speeds.

This end mill is suited for use on vertical machining centers, CNC mills, and manual knee mills in job shop, production, and tool-and-die environments. The 6 inch overall length gives operators extended reach for deeper workpiece features without sacrificing rigidity. The helical flute geometry promotes efficient chip evacuation, reducing heat buildup during continuous cuts. Machinists and tooling technicians working in aerospace, automotive, and general precision machining will find this geometry appropriate for finishing and semi-finishing passes.

Key Features

• Centercutting design allows direct plunge entry into the workpiece
• 4 helical flutes for efficient chip evacuation and improved surface finish
• Solid carbide construction for rigidity and extended tool life
• 5/16 inch mill diameter with matching cylindrical shank for standard collet compatibility
• 1-1/2 inch length of cut supports slotting, pocketing, and profiling
• 6 inch overall length provides extended reach for deeper features

Compatibility

Designed as a standard solid carbide square end mill for use in 5/16 inch collets, ER collet chucks, and end mill holders on CNC and manual milling machines.

Installation Notes

Installation is performed by a machinist or tooling technician. Ensure the machine spindle is fully stopped and locked out before changing tooling. Insert the cylindrical shank to the recommended engagement depth in the collet or tool holder and torque the retention hardware per the tool holder manufacturer guidelines. Inspect the cutting edges for chips or wear before each use.
