Accupro 310505 Square End Mill 3/4 in 4 Flute Solid Carbide

Product Description

The ACCUPRO 310505 is a solid carbide square end mill designed for high-performance metal removal in demanding machining applications. It features a 3/4 inch diameter with a 3-1/4 inch length of cut, a 3/4 inch shank diameter, and a 6 inch overall length. The 4-flute geometry with a 38-degree helix angle promotes efficient chip evacuation and surface finish quality. An AlTiCrN coating provides thermal resistance and extended tool life in ferrous materials and hardened steels. This end mill is installed by machinists and CNC operators working in job shop, toolroom, and production environments.

This end mill is suited for milling operations in ferrous and non-ferrous metals where a long length of cut is required. The single-end configuration and right-hand cutting direction make it compatible with standard CNC machining centers and manual mills. The variable index flute spacing helps reduce harmonic vibration during deep-pocket and side-wall milling. Its micrograin carbide substrate supports aggressive feed rates in materials where tool deflection and wear resistance are critical considerations.

Key Features

• 3/4 inch diameter with 3/4 inch shank for direct collet or end mill holder mounting
• 3-1/4 inch length of cut enables deep-pocket and extended-reach milling
• AlTiCrN coating delivers high-temperature oxidation resistance and reduced tool wear
• 38-degree helix angle promotes smooth chip flow and reduced cutting forces
• Variable index flute spacing minimizes chatter in extended-reach applications
• Micrograin solid carbide substrate provides hardness and edge retention
• Centercutting design allows direct plunge entry

Compatibility

Designed as an OEM-style replacement and production-grade solid carbide square end mill for use in standard 3/4 inch end mill holders, collet chucks, and hydraulic tool holders on CNC machining centers and manual milling machines. Part of the ACCUPRO Series HS product line.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the machine spindle and tool holder are free of chips and contaminants before seating the shank. Torque set-screws or collet nuts to the tool holder manufacturer specification using the appropriate wrench. Confirm runout with a dial indicator before beginning the cut, particularly given the extended length of cut on this tool.
