Accupro 72032816 Ball End Mill 1/4 in 6 Flute Solid Carbide

Product Description

The ACCUPRO 72032816 is a solid carbide ball end mill designed for high-performance milling in demanding materials. Built with a 1/4 inch diameter and six flutes, it delivers superior chip evacuation and surface finish in difficult-to-machine workpiece materials. The AlTiN+ coating provides thermal resistance and extended tool life under elevated cutting temperatures. A variable helix angle of 36 and 40 degrees, combined with a variable index, reduces chatter and vibration during aggressive cuts. This tool is intended for use by machinists and CNC operators working with high-temp alloys and similar hard materials.

This end mill is suited for precision milling operations in aerospace, medical, and industrial manufacturing environments where tight tolerances and finish quality are required. The centercutting geometry allows for plunge entry, and the right-hand cutting and flute direction make it compatible with standard CNC machining centers and manual mills. With a 3/8 inch length of cut and 2 inch overall length, it fits compact toolpath requirements without sacrificing rigidity.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard materials
• AlTiN+ coating for high-heat resistance and extended tool life
• Six-flute design improves chip evacuation and surface finish
• Variable helix (36 and 40 degrees) and variable index reduce vibration and chatter
• Centercutting geometry allows direct plunge milling
• Single-end, straight shank design for standard collet and toolholder compatibility

Compatibility

Designed for use in standard 1/4 inch straight-shank toolholders and collet chucks on CNC machining centers and manual mills. Primary workpiece material designation is High-Temp Alloy (material code S), covering nickel-based, titanium, and cobalt alloys.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and locked out before loading or removing the tool. Seat the straight shank fully into the collet or toolholder to the recommended engagement depth before torquing. Verify runout with a dial indicator before beginning a production run, as excessive runout will accelerate tool wear and degrade surface finish.
