Accupro 12180928 Ball End Mill 0.5in 2 Flute Solid Carbide

Product Description

The ACCUPRO 12180928 is a solid carbide ball end mill designed for precision milling operations in metalworking applications. With a 0.5-inch cutting diameter and a 0.5-inch length of cut, it delivers consistent, accurate profiles in contoured and 3D surface work. The two-flute design balances chip evacuation with cutting strength, while the AlTiN coating improves heat resistance and extends tool life in ferrous and hard-material applications. The 30-degree helix angle supports smooth cutting action and reduces chatter. This tool is installed and operated by machinists and CNC programmers working in job shop, production, and tool-and-die environments.

This ball end mill suits finishing and semi-finishing passes on molds, dies, contoured surfaces, and complex 3D geometry in CNC machining centers and manual mills. The single-end, right-hand cutting configuration with right-hand flute direction is standard for the majority of vertical and horizontal milling setups. The micrograin solid carbide substrate handles hardened steels, stainless, cast iron, and high-temperature alloys where high-speed steel tooling falls short.

Key Features

• 0.5-inch ball nose diameter for precise contour and 3D surface milling
• AlTiN coating provides elevated heat resistance and extended tool life in ferrous materials
• Micrograin solid carbide substrate delivers rigidity and wear resistance
• 30-degree helix angle reduces cutting forces and minimizes chatter
• Two-flute geometry promotes efficient chip evacuation in slotting and profiling
• Single-end design with right-hand cut and right-hand spiral flute direction

Compatibility

Designed as a standard shank replacement or new-install ball end mill for CNC machining centers and manual milling machines accepting a 0.5-inch straight shank toolholder or collet.

Installation Notes

Installation is performed by a qualified machinist or CNC setup technician. Ensure the machine spindle is fully stopped and locked out before installing or removing the tool. Seat the 0.5-inch shank fully and evenly in the collet or toolholder to the recommended minimum engagement depth per the toolholder manufacturer. Verify runout with a dial indicator before beginning the cut, as excessive runout accelerates edge wear and reduces surface finish quality.
