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.\u003c\/p\u003e\u003cp\u003eThis 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.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAlTiCrN coating for elevated heat resistance and extended wear life in hard material applications\u003c\/li\u003e\n\u003cli\u003e4-flute design promotes efficient chip removal and improved surface finish\u003c\/li\u003e\n\u003cli\u003eVariable index flute spacing reduces harmonic vibration and chatter during cutting\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction provides rigidity and dimensional stability\u003c\/li\u003e\n\u003cli\u003eSingle-end ball geometry enables full 3D contouring and profiling operations\u003c\/li\u003e\n\u003cli\u003e1\/8 inch diameter and 0.1160 inch length of cut suited for fine detail and tight-pocket work\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned 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.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified machinists or CNC setup technicians.
