Accupro 14883931 Ball End Mill 0.025 in 3 Flute Altin Carbide

Product Description

The ACCUPRO 14883931 is a miniature solid carbide ball end mill designed for high-precision milling of tight-tolerance features, small radii, and intricate contours in hard and abrasive materials. The 0.025-inch cutting diameter and 3-flute geometry make it well suited for fine detail work where chip evacuation and surface finish are critical. An AlTiN coating extends tool life by improving heat resistance and reducing friction at the cutting edge. The 30-degree helix angle promotes smooth cutting action and efficient chip flow. This tool is intended for use by machinists and tooling professionals on CNC machining centers and high-speed spindles requiring sub-0.1-inch tooling.

This end mill is used in applications demanding micro-scale material removal, including mold and die work, aerospace components, medical device manufacturing, and precision prototype machining. The miniature series designation indicates it is optimized for small-feature work where standard-size tooling cannot access part geometry. The extended reach neck and 1/8-inch shank allow use in standard collet systems while reaching into recessed features. The 0.037-inch length of cut keeps the cutting zone controlled for dimensional accuracy in shallow passes.

Key Features

• 0.025-inch ball nose diameter for micro-scale contouring and radius work
• 3-flute spiral design balances chip evacuation with cutting stability at small diameters
• AlTiN coating for elevated heat resistance and extended tool life in hard materials
• 30-degree right-hand helix with right-hand cutting direction for standard CNC spindle compatibility
• Extended reach neck with 0.203-inch neck length for access to recessed or deep features
• Micrograin solid carbide substrate for rigidity and wear resistance at miniature scale

Compatibility

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

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer guidelines for tool runout and collet torque. Ensure the spindle and collet are clean and free of debris before seating the shank. Verify shank engagement depth meets minimum pull-out resistance requirements for the selected collet system. At this diameter, tool deflection and runout are critical factors — confirm total indicated runout before beginning cuts.
