Accupro 12184213 Ball End Mill 0.125 in 2 Flute Carbide Altin

Product Description

The ACCUPRO 12184213 is a solid carbide ball end mill designed for precision milling of contoured surfaces, slots, and complex 3D profiles. With a 0.125-inch cutting diameter and a 2-flute geometry, this tool delivers efficient chip evacuation and a clean finish in a wide range of workpiece materials. The 40-degree helix angle promotes smooth cutting action and reduced chatter. An AlTiN coating provides elevated heat resistance and extends tool life in dry or high-speed machining environments. At 2.25 inches overall length with a 0.75-inch length of cut, this is a long-series configuration suited for applications requiring reach beyond a standard stub-length tool.

This end mill is used in CNC machining centers and manual mills for finishing and semi-finishing passes on contoured parts, die and mold work, and complex profiled features. The single-end, right-hand cutting direction suits standard spindle rotation. The micrograin carbide substrate maintains edge sharpness under thermal and mechanical load, making this tool appropriate for hardened steels, stainless alloys, cast iron, and non-ferrous materials at elevated surface speeds. Machinists and tool-and-die professionals working in job shops, aerospace, and general metalworking will find this tool applicable to a broad range of production and prototype applications.

Key Features

• Solid micrograin carbide substrate for rigidity and edge retention
• AlTiN coating for heat resistance and extended tool life in dry high-speed cutting
• 40-degree helix angle for smooth cutting action and reduced cutting forces
• 2-flute design promotes chip evacuation in slotting and profiling operations
• Long-series length of cut (0.75 inches) provides reach for deeper features
• Right-hand cut and right-hand spiral flute for standard CNC spindle compatibility

Compatibility

Designed as an OEM-style replacement and standard production tool compatible with CNC machining centers and manual mills accepting a 0.125-inch straight shank collet or end mill holder.

Installation Notes

Installation is performed by qualified machinists using a compatible collet chuck, shrink-fit holder, or set-screw style end mill holder rated for the shank diameter. Ensure the spindle and holder are clean and free of chips before seating the tool. Verify runout with a dial indicator before beginning a cut, as excessive runout accelerates wear on small-diameter carbide tools. Power down and lock out the spindle before any tool change.
