Accupro 12184084 Ball End Mill 0.118 in 2 Flute Altin Carbide

Product Description

The ACCUPRO 12184084 is a solid carbide ball end mill designed for high-precision milling operations in metalworking and machining applications. It features a 0.118 inch (3 mm) mill diameter with a 0.2362 inch (6 mm) length of cut, a 3 mm shank diameter, and an overall length of 38 mm. The micrograin carbide substrate provides edge stability at elevated cutting speeds, while the AlTiN coating improves heat resistance and extends tool life in ferrous and hard-material applications. The 40-degree helix angle promotes efficient chip evacuation and reduces cutting forces. This is a single-end, stub-length tool with right-hand cut and right-hand spiral flutes, suited for CNC machining centers and high-speed milling setups.

This end mill is intended for use on CNC vertical and horizontal machining centers where small-diameter, tight-tolerance ball-end profiles are required. Typical applications include die and mold work, contour milling, 3D profiling, and finishing passes on hardened steels, stainless steels, cast iron, and similar materials. The stub length configuration provides added rigidity, making it well-suited for setups where deflection control is critical. Machinists and tool-and-die professionals working with small-bore cavities and intricate surface geometries will find this geometry appropriate for their requirements.

Key Features

• 0.118 inch (3 mm) ball end diameter for small-radius profiling and contouring
• AlTiN coating for elevated heat resistance and extended tool life in hard and ferrous materials
• Micrograin solid carbide substrate for rigidity and edge retention
• 40-degree helix angle promotes efficient chip evacuation and smooth cutting action
• Stub length configuration reduces deflection in demanding setups
• Right-hand cut, right-hand spiral flutes — standard for most CNC milling operations

Compatibility

Designed as a direct-mount cutting tool for CNC machining centers and milling machines that accept 3 mm straight shank toolholders, collets, or shrink-fit holders.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Ensure the machine spindle is fully stopped and locked out before inserting or removing the tool from its holder. Seat the shank fully into the collet or toolholder and torque the retention mechanism to the toolholder manufacturer's specification. Verify runout with a dial indicator before beginning a production cut, especially given the small diameter and the tight tolerances typical of die and mold work.
