Accupro 12179282 Ball End Mill 0.5 in 4 Flute Solid Carbide

Product Description

The ACCUPRO 12179282 is a solid carbide ball end mill designed for precision milling operations in ferrous and non-ferrous materials. With a 0.5 inch cutting diameter, a 2 inch length of cut, and four right-hand spiral flutes at a 40-degree helix angle, this tool delivers efficient chip evacuation and smooth surface finishes. The nACRo coating provides enhanced wear resistance and thermal protection, extending tool life in demanding cutting conditions. It is a single-end tool ground from micrograin carbide for consistent edge integrity and dimensional accuracy within a mill diameter tolerance of +0.000 to -0.002 inches.

This end mill is suited for die and mold work, contour milling, profiling, and finishing passes in machining centers. The ball nose geometry makes it the right choice for 3D contouring, curved surface work, and slotting in applications where a radiused tip is required. The 0.5 inch shank diameter fits standard ER and end mill holders common in CNC machining environments. It is used by machinists and tooling shops working in steel, stainless, cast iron, and high-temperature alloys where a coated carbide tool is specified.

Key Features

• Solid micrograin carbide construction for rigidity and edge retention
• nACRo coating for improved wear resistance and heat resistance in hard material cutting
• 40-degree helix angle promotes efficient chip evacuation and reduces cutting forces
• Four right-hand flutes with right-hand cutting direction for standard CNC spindle compatibility
• Mill diameter tolerance of +0.000 to -0.002 inches for precise dimensional control
• Single-end design with 4 inch overall length and 2 inch length of cut

Compatibility

Designed as an OEM-style solid carbide ball end mill for use in standard 0.5 inch end mill holders and collet chucks on CNC machining centers. No specific machine model compatibility was provided in the product data.

Installation Notes

Installation is performed by a machinist or CNC tooling technician. The machine spindle must be fully stopped and the tool holder secured before inserting or removing the end mill. Ensure the shank is seated to the correct gauge length in the holder and that the set screw or collet nut is torqued according to the holder manufacturer's specifications. Inspect the cutting edges before use and do not exceed the recommended depth of cut or feed rate for the workpiece material and machine rigidity.
