Accupro 12184537 Ball End Mill 1/2 in 3 Flute Solid Carbide Altin

Product Description

The ACCUPRO 12184537 is a solid carbide ball end mill designed for precision milling of contoured surfaces, cavities, and complex 3D profiles in ferrous and non-ferrous materials. With a 1/2 inch mill diameter, 1-1/2 inch length of cut, and a 40-degree helix angle, this tool delivers aggressive chip evacuation and smooth surface finishes in demanding cutting conditions. The AlTiN coating provides elevated heat resistance, making it well-suited for dry or high-speed machining of hardened steels, stainless, and cast iron. Micrograin carbide substrate adds toughness and wear resistance over extended run times.

This end mill is intended for CNC machining centers, vertical mills, and multi-axis machining applications in production shop and job shop environments. The extra-long overall length of 6 inches allows access to deep pockets, tall workpieces, and setups requiring extended reach. The single-end, right-hand cutting configuration suits standard climb and conventional milling operations. Machinists and CNC programmers working in aerospace, die-mold, and precision manufacturing will find this tool appropriate for finishing and semi-finishing passes on complex geometries.

Key Features

• 1/2 inch diameter ball end profile for contoured and 3D surface milling
• AlTiN coating for high-temperature resistance and extended tool life in hard materials
• 40-degree helix angle promotes efficient chip evacuation and reduces cutting forces
• Micrograin solid carbide substrate for improved wear resistance and edge retention
• Extra-long 6 inch overall length provides extended reach for deep-pocket applications
• 3-flute spiral flute design balances chip clearance with rigidity

Compatibility

Designed as a direct-fit replacement or standard tooling option for CNC machining centers and manual vertical mills accepting a 1/2 inch shank diameter collet or end mill holder.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Secure the 1/2 inch shank in a properly sized collet, end mill holder, or shrink-fit toolholder, and confirm runout with a dial indicator before commencing cuts. Ensure the spindle is fully stopped and the machine is in an energy-isolated state before tool changes. Avoid side-loading the tool beyond its rated depth of cut to prevent deflection or breakage, particularly given the extended-reach length.
