Accupro 14881941 Ball End Mill 5/64 in 3 Flute Carbide

Product Description

The ACCUPRO 14881941 is a solid carbide ball end mill designed for precision milling in tight geometries and small-feature work. Built from micrograin carbide, this single-end tool measures 0.0781 inches (5/64 inches) in mill diameter with a 3-flute spiral configuration and a 30-degree helix angle. The ball nose profile generates smooth, contoured cuts in slots, pockets, and 3D surface profiles. At 3 inches overall length with an extended-reach neck of 1.95 inches, it reaches into deep cavities while maintaining rigidity. The bright, uncoated finish makes it suitable for non-ferrous metals, plastics, and graphite where coating buildup is a concern. A licensed machinist or CNC operator typically installs and runs this tool.

This miniature ball end mill fits applications where small-diameter, high-precision cutting is required. Typical uses include die and mold work, medical component machining, electronics fixtures, and fine detail work in aerospace and prototype environments. The 1/8-inch shank diameter is compatible with standard collet systems on CNC machining centers and high-speed spindles. The right-hand cut and right-hand flute direction are standard for conventional CNC milling setups. The extended neck geometry allows access to recessed features without tool holder interference.

Key Features

• Micrograin solid carbide construction for wear resistance and edge stability at small diameters
• 0.0781 inch (5/64 inch) ball nose diameter for fine-detail contour milling
• 3-flute spiral design improves chip evacuation and surface finish
• 30-degree helix angle balances cutting efficiency and tool rigidity
• Extended reach with 1.95 inch neck length for deep-cavity access
• Bright, uncoated finish suited to non-ferrous and abrasive non-metallic materials

Compatibility

Designed for use in CNC machining centers and high-speed spindles equipped with 1/8-inch collet systems; fits standard ER and precision collet holders accepting that shank diameter.

Installation Notes

Installation should be performed by a qualified CNC machinist or toolroom technician. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing tooling. Seat the 1/8-inch shank fully into the collet and torque the colret nut to the collet manufacturer's specification. Verify runout with a dial indicator before cutting, as excessive runout at this small diameter will accelerate tool wear and degrade part quality.
