Accupro 72078074 3/8 Inch 6 Flute Solid Carbide Square End Mill

Product Description

The ACCUPRO 72078074 is a solid carbide square end mill designed for high-performance material removal in demanding machining applications. Built with six flutes and an AlTiN+ coating, it is engineered for cutting high-temperature alloys and other difficult-to-machine materials where heat resistance and edge retention are critical. The variable helix angle, ranging from 36 to 40 degrees, and variable index geometry reduce harmonic vibration during cutting, improving surface finish and tool life. This is a single-end, right-hand cutting tool with a 3/8 inch diameter and a 1.0 inch length of cut, making it suitable for finishing and semi-finishing passes in milling operations.

This end mill is intended for use in CNC machining centers and manual mills across aerospace, defense, and industrial manufacturing environments where high-temp alloys such as Inconel, titanium, and similar superalloys are common workpiece materials. The centercutting design allows for plunge entry as well as conventional peripheral milling. It is typically selected by machinists and CNC programmers when toolpath stability and thermal resistance are prioritized over high-feed roughing strategies.

Key Features

• AlTiN+ coating provides high oxidation resistance and hardness at elevated cutting temperatures
• Variable helix and variable index geometry reduce chatter and improve surface finish
• Six flutes increase material removal rate compared to standard four-flute designs
• Centercutting construction enables plunge milling entry
• Right-hand cut and right-hand flute direction for standard CNC spindle compatibility
• Solid carbide construction delivers rigidity and wear resistance in hard and abrasive materials

Compatibility

Designed for machining high-temperature alloys (workpiece material code S), this end mill is suited for applications where AlTiN+ coated solid carbide tooling is specified. Confirm shank and collet compatibility before installation.

Installation Notes

This tool is installed by machinists or CNC setup technicians in a compatible collet or end mill holder sized for a 3/8 inch shank diameter. Ensure the spindle and tool holder are clean and free of runout before seating the tool. Follow machine manufacturer guidelines for toolholder torque and overhang length. Always verify workpiece clamping and machine zero points before initiating a cutting cycle.
