Accupro 12184192 Ball End Mill 0.4844in 2 Flute Carbide

Product Description

The ACCUPRO 12184192 is a single-end ball end mill designed for contour milling, profiling, and 3D surface work in CNC machining centers and manual mills. Built from micrograin solid carbide, it delivers the rigidity and edge retention needed for harder workpiece materials. The cutting diameter is 0.4844 inches (31/64 inches) with a 0.625-inch length of cut, and the tool carries an AlTiN coating for improved heat resistance and tool life at elevated cutting speeds. The 40-degree helix angle promotes smooth chip evacuation and reduces cutting forces on the workpiece. This tool is installed and used by machinists, toolroom technicians, and CNC operators.

This ball end mill is suited for milling operations requiring a full-radius cutting profile, including die and mold work, slotting, and finish profiling on ferrous and non-ferrous materials. The AlTiN coating makes it a practical choice for dry or semi-dry cutting in alloy steels, stainless steels, and hardened materials where heat generation is a concern. The 0.5-inch shank diameter fits standard ER collet chucks, end mill holders, and shrink-fit toolholders sized for 1/2-inch shanks.

Key Features

• Micrograin solid carbide substrate for superior hardness and edge retention
• AlTiN coating provides thermal barrier for dry or high-speed cutting applications
• 40-degree helix angle promotes efficient chip evacuation and reduces cutting forces
• 2-flute geometry optimized for profiling and 3D contouring operations
• Right-hand cut and right-hand spiral flute configuration
• Single-end design with stub length classification for added rigidity

Compatibility

Designed for use in CNC machining centers and manual milling machines with standard 1/2-inch shank toolholders, including ER collet chucks and end mill holders.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and the tool changer or drawbar is disengaged before seating or removing the tool. Verify the shank is clean and fully engaged in the toolholder to the recommended insertion depth before tightening. Confirm runout with a dial indicator before beginning a production run to avoid premature tool wear or part error.
