Accupro 314960 Square End Mill 5/8 Inch 3 Flute Carbide Zrn

Product Description

The ACCUPRO 314960 is a solid carbide square end mill designed for precision milling operations in metal, composites, and engineering plastics. It measures 0.625 inches in diameter with a 3.25-inch length of cut and a 6-inch overall length, making it well-suited for deep-reach slotting, profiling, and contouring applications. The three-flute geometry balances chip evacuation with rigidity, while the ZrN (zirconium nitride) coating reduces friction and extends tool life in ferrous and non-ferrous materials. Micrograin carbide construction provides consistent edge integrity under demanding feed rates. Licensed machinists, CNC programmers, and toolroom technicians are the primary users of this end mill.

This end mill fits standard CNC machining centers, vertical mills, and manual knee mills equipped with a 5/8-inch collet or end mill holder. The centercutting design allows plunge entry as well as conventional peripheral cutting. Right-hand cut and right-hand spiral flute configuration make it compatible with standard spindle rotation on the vast majority of production and toolroom equipment. The 37-degree helix angle promotes smooth chip flow and reduced cutting forces, which is beneficial when machining aluminum alloys, stainless steels, and medium-carbon steels.

Key Features

• Solid micrograin carbide construction for extended edge life and dimensional stability
• ZrN coating reduces friction and heat buildup at the cutting edge
• 37-degree helix angle promotes efficient chip evacuation and lower cutting forces
• Centercutting design enables both plunge and peripheral entry
• Three-flute geometry balances rigidity with chip clearance in medium to high feed-rate applications
• Right-hand cut and right-hand flute for compatibility with standard CNC and manual spindles

Compatibility

Designed for use in 5/8-inch collets or end mill holders on CNC machining centers, vertical mills, and toolroom equipment requiring a standard straight-shank solid carbide square end mill.

Installation Notes

Installation should be performed by qualified machinists or CNC technicians following shop safety protocols. Ensure the spindle is fully stopped and the machine is locked out before changing tooling. Seat the shank fully into the collet or holder to the recommended grip depth to prevent pullout under load. Verify runout with a dial indicator before beginning cuts, particularly in tight-tolerance applications.
