Accupro 14881931 Ball End Mill 0.0625 in 3 Flute Solid Carbide

Product Description

The ACCUPRO 14881931 is a miniature solid carbide ball end mill designed for precision milling operations requiring tight tolerances and fine surface finishes. It features a 0.0625-inch (1/16 inch) mill diameter with a 3-flute spiral geometry and a 30-degree helix angle, making it well-suited for contour milling, profiling, and finishing passes in hard or abrasive materials. The AlTiN coating provides thermal resistance and extended tool life in dry or semi-dry cutting conditions. Micrograin carbide construction ensures rigidity and edge retention at small diameters. Licensed machinists and CNC programmers install this tool in machining centers and CNC milling machines where miniature toolpaths and precise radii are required.

This end mill is intended for small-feature milling applications in aerospace, medical device, die and mold, and precision job-shop environments. Its extended-reach design, with a 3/4-inch neck length and 2.5-inch overall length, allows access to recessed features and deep pockets without interference. The 1/8-inch shank diameter fits standard collets and tool holders used with miniature tooling setups. Right-hand cutting and right-hand flute direction are standard for conventional CNC milling machine spindle rotation.

Key Features

• 0.0625-inch ball end diameter with mill diameter tolerance of +0.0000 / -0.0010 inches for precise radii
• 3-flute spiral geometry with 30-degree helix angle for improved chip evacuation and surface finish
• AlTiN coating for high-temperature resistance and extended tool life in abrasive materials
• Micrograin solid carbide construction provides rigidity and edge retention at small diameters
• Extended-reach design with 3/4-inch neck length for access to deep or recessed features
• Single-end configuration with right-hand cut and right-hand flute direction

Compatibility

Designed as an OEM-style miniature ball end mill for use in standard 1/8-inch collets and tool holders on CNC milling machines and machining centers requiring small-diameter tooling.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the machine spindle is fully stopped and the tool changer or collet is de-energized before inserting or removing the tool. Use a properly sized collet or tool holder matched to the 1/8-inch shank diameter and verify runout with a dial indicator before beginning a production run. At this diameter, excessive overhang or improper clamping can result in tool deflection or breakage.
