Accupro 39157656 Ball End Mill 1/8 in 4 Flute Solid Carbide

Product Description

The ACCUPRO 39157656 is a solid carbide ball end mill designed for precision milling of complex contours, profiles, and curved surfaces in ferrous and non-ferrous materials. Built with four flutes and a variable index geometry, it delivers improved chip evacuation and reduced chatter compared to fixed-index designs. The cutting edge carries an AlTiCrN coating, which provides high heat resistance and extended tool life in demanding machining environments. With a 1/8 inch diameter and a 0.1160 inch length of cut, this mill suits fine detail work in die, mold, and precision component machining. It is installed by machinists in CNC machining centers and manual milling operations.

This ball end mill is suited for finishing passes and contouring operations in precision machining environments. The 1/8 inch shank diameter fits standard collet systems commonly found on CNC vertical machining centers and high-speed spindle setups. Its single-end configuration and compact overall length of 1-1/2 inches make it well-suited for tight-tolerance work in die and mold applications where rigidity and runout control are critical.

Key Features

• AlTiCrN coating for elevated heat resistance and extended wear life in hard material applications
• 4-flute design promotes efficient chip removal and improved surface finish
• Variable index flute spacing reduces harmonic vibration and chatter during cutting
• Solid carbide construction provides rigidity and dimensional stability
• Single-end ball geometry enables full 3D contouring and profiling operations
• 1/8 inch diameter and 0.1160 inch length of cut suited for fine detail and tight-pocket work

Compatibility

Designed as a direct-fit replacement for 1/8 inch shank ball end mills used in standard collet chucks and end mill holders on CNC machining centers and manual mills.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Secure the shank fully within the collet or end mill holder to the recommended grip length before torquing the retention nut. Verify runout with a dial indicator before commencing a cut. Follow all machine guarding and chip containment protocols during operation.
