Accupro 12464163 Ball End Mill 0.065 in 4 Flute Solid Carbide

Product Description

The ACCUPRO 12464163 is a single-end ball end mill designed for precision milling operations requiring a small-diameter cutting tool. Built from solid carbide micrograin material, it delivers the hardness and wear resistance needed for close-tolerance work in ferrous and non-ferrous materials. The 0.0650-inch cutting diameter pairs with an AlTiN coating that improves heat resistance and extends tool life at elevated cutting speeds. With 4 flutes and a 30-degree helix angle, this end mill promotes efficient chip evacuation and smooth surface finishes in miniature-scale cuts. Licensed machinists and tool-and-die professionals install this type of tooling on CNC machining centers and manual mills where fine-feature work is required.

This miniature series ball end mill suits applications in mold making, die work, medical component machining, and aerospace part production where small radii and tight tolerances are standard requirements. The 0.1950-inch length of cut allows for moderate-depth passes in slotting, profiling, and contouring operations. The 1/8-inch shank diameter fits standard ER collet chucks and miniature end mill holders commonly found in small-part machining setups. It is appropriate for use in both production and prototype environments where dimensional accuracy is critical.

Key Features

• 0.0650-inch ball end cutting diameter with a tolerance of +0.0000 / -0.0010 inches for consistent sizing
• Solid carbide micrograin construction for rigidity and extended tool life
• AlTiN coating provides high-temperature resistance and reduces friction during cutting
• 4-flute, 30-degree right-hand spiral design promotes chip flow and surface finish quality
• 1/8-inch shank diameter with a tolerance of -0.0001 / -0.0003 inches for secure collet holding
• Single-end configuration, miniature series, no chipbreaker

Compatibility

Designed as an OEM-style miniature ball end mill for use in standard 1/8-inch collet chucks, ER collet systems, and miniature end mill holders on CNC machining centers and manual milling machines.

Installation Notes

Installation and tool changes must be performed with the machine spindle fully powered down and the control in an e-stop or locked-out state per applicable shop safety procedures. Seat the shank fully into the collet or tool holder and torque the retention system according to the holder manufacturer's specifications. Inspect the cutting edges and coating under magnification before use; carbide tooling is brittle and should never be used if chipping or cracking is visible. Speeds and feeds for AlTiN-coated carbide should be selected based on workpiece material, machine rigidity, and the depth of cut being taken.
