Accupro 14881916 Ball End Mill 3/32 in 3 Flute Carbide Altin

Product Description

The ACCUPRO 14881916 is a miniature solid carbide ball end mill designed for precision milling of contoured surfaces, complex 3D profiles, and tight-tolerance features in hardened and difficult-to-machine materials. Built with a 3-flute, single-end configuration and a 30-degree helix angle, it delivers efficient chip evacuation and smooth cutting action at small diameters. The AlTiN coating extends tool life in high-heat applications by providing thermal and oxidation resistance. At 0.0938 inches in diameter with a 0.1390-inch length of cut, this end mill is suited for fine detail work where conventional tooling cannot reach.

This end mill is used in CNC machining centers and manual mills for finishing passes on molds, dies, aerospace components, and medical device parts where small-diameter, high-precision cutting is required. The extended-reach geometry and 0.9500-inch neck length allow access to recessed features and deep pockets without interference. Typical applications include finishing hardened tool steels, stainless alloys, and titanium alloys in both job shop and production environments.

Key Features

• 0.0938-inch (3/32 inch) ball nose diameter for fine detail and contour milling
• 3-flute spiral design promotes chip clearance and surface finish quality
• AlTiN coating provides heat resistance and extended tool life in hard materials
• 30-degree helix angle balances cutting forces and reduces chatter at small diameters
• Extended-reach configuration with 0.9500-inch neck length for deep-pocket access
• Micrograin solid carbide construction for rigidity and wear resistance

Compatibility

Designed as a miniature series replacement-style ball end mill compatible with standard 1/8-inch shank collets and toolholders used in CNC machining centers and precision milling operations.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Power down and lock out the spindle before changing tooling. Seat the 1/8-inch shank fully in the collet and torque to the toolholder manufacturer's specification. Inspect the cutting edges and coating for damage before use, as miniature carbide end mills are susceptible to breakage if runout is excessive or clamping is improper.
