Accupro 312610 Square End Mill 3/8 in 7 Flute Solid Carbide

Product Description

The ACCUPRO 312610 is a solid carbide square end mill designed for high-performance milling in demanding metalworking applications. The 3/8 inch diameter cutter features 7 flutes and a 38-degree helix angle, delivering smooth chip evacuation and improved surface finish at aggressive feed rates. An AlTiCrN coating provides high heat resistance and extended tool life when cutting hardened steels, stainless alloys, and other abrasive materials. With a 2-1/2 inch length of cut and 6 inch overall length, this end mill suits deep-cavity and extended-reach milling operations. It is installed and operated by machinists and tool-and-die professionals on CNC vertical machining centers and manual knee mills.

This end mill is built for milling operations in aerospace, die and mold, and general machining environments where tool life and dimensional accuracy are critical. The 7-flute, right-hand spiral geometry with micrograin carbide substrate is suited for finishing and semi-finishing passes in ferrous metals and hardened workpiece materials. The 3/8 inch shank diameter fits standard ER and end mill holders commonly found in production and job-shop settings.

Key Features

• 3/8 inch diameter with 7-flute geometry for high metal removal rates and superior finish
• AlTiCrN coating for oxidation resistance and extended tool life in high-heat applications
• 38-degree helix angle promotes efficient chip evacuation in deep pockets and slots
• Micrograin solid carbide substrate provides rigidity and wear resistance
• Right-hand cutting and right-hand flute direction for standard CNC spindle compatibility
• 6 inch overall length supports extended-reach and deep-cavity milling setups

Compatibility

Designed as an OEM-style replacement and standard production end mill for CNC machining centers and manual mills accepting 3/8 inch straight-shank end mill holders.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer guidelines for tool holding and runout tolerances. Ensure the spindle and tool holder are clean and free of debris before seating the shank. Confirm appropriate collet or end mill holder torque per the holder manufacturer specification before initiating a cut. Always verify spindle speed and feed rate parameters against published cutting data for the workpiece material before engaging the tool.
