Accupro 14881967 Ball End Mill 0.0312 in 3 Flute Altin Carbide

Product Description

The ACCUPRO 14881967 is a miniature solid carbide ball end mill designed for precision milling in tight geometries and small-feature work. The tool measures 0.0312 inches in diameter with a 0.046-inch length of cut, making it well suited for intricate contouring, slotting, and profiling where tool path accuracy is critical. It features three flutes with a 30-degree helix angle and is finished with an AlTiN coating for improved heat resistance and extended tool life in harder workpiece materials. Overall length is 2.5 inches with a 1/8-inch shank diameter. The micrograin carbide substrate supports edge retention in demanding cutting conditions. This tool is installed and operated by machinists and CNC programmers in job shop and production environments.

The 14881967 is suited for small-feature milling in mold and die work, aerospace components, medical device machining, and general precision part production. The extended reach design, with a 5/8-inch neck length, allows access to recessed features and deep pockets without interference from the shank. The single-end configuration and right-hand cutting and flute direction are standard for conventional CNC machining center setups. This tool is appropriate for use in materials ranging from aluminum and non-ferrous alloys to hardened steels where the AlTiN coating provides a thermal and wear barrier.

Key Features

• 0.0312-inch ball diameter for small-feature and fine-detail milling
• AlTiN coating improves heat resistance and wear life in harder materials
• 3-flute geometry balances chip evacuation and surface finish
• 30-degree helix angle reduces cutting forces and improves finish quality
• Extended reach with 5/8-inch neck length for deep or recessed features
• Micrograin solid carbide substrate for edge retention and rigidity

Compatibility

Designed as an OEM-style miniature ball end mill for use in CNC machining centers and high-speed spindles accepting a 1/8-inch straight shank collet or toolholder.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the spindle is fully powered down and the machine is in a safe state before loading or removing tooling. Use a precision collet or shrink-fit holder rated for the 1/8-inch shank diameter to maintain runout tolerances appropriate for miniature tooling. At small diameters, excessive overhang or collet contamination can significantly increase runout and lead to premature tool failure or breakage.
