Accupro 314941 Square End Mill 5/8 in 3 Flute Solid Carbide Zrn

Product Description

The ACCUPRO 314941 is a solid carbide square end mill designed for precision milling operations in metal, composites, and similar materials. It features a 5/8 inch cutting diameter with a 2 inch length of cut and a 5 inch overall length. The three-flute geometry with a 37-degree helix angle promotes efficient chip evacuation and smooth cutting action. A zirconium nitride (ZrN) coating reduces friction and improves wear resistance during high-speed operations. Micrograin carbide construction delivers hardness and edge retention well beyond high-speed steel alternatives. This tool is intended for installation in CNC machining centers and manual mills by machinists working in production and maintenance environments.

This end mill is suited for slotting, profiling, and peripheral milling in ferrous and non-ferrous applications where a square corner finish is required. The centercutting design allows plunge entry, adding flexibility in pocket milling scenarios. Right-hand cut and right-hand flute orientation match standard spindle rotation on the majority of vertical machining centers. The spiral flute with fixed helix keeps chatter low across a wide range of feed and speed parameters, making it a reliable general-purpose tool for job shops and production floors alike.

Key Features

• Solid micrograin carbide construction for superior hardness and edge retention
• ZrN coating reduces friction and extends tool life in abrasive materials
• 37-degree helix angle promotes efficient chip evacuation and reduced cutting forces
• Centercutting design permits direct plunge entry for pocket milling
• Three-flute spiral geometry balances chip clearance with surface finish quality
• Right-hand cut and right-hand flute for standard CNC spindle compatibility

Compatibility

Designed as a standard shank end mill for use in CNC machining centers, knee mills, and similar equipment fitted with collet chucks or end mill holders accepting a 5/8 inch shank diameter.

Installation Notes

Installation should be performed by a qualified machinist. Secure the shank in a properly sized collet or end mill holder, ensuring adequate shank engagement to prevent pullout under load. Power down and lock out the spindle before changing tooling. Follow machine manufacturer guidelines and applicable shop safety standards when setting cutting parameters.
