Accupro 14881901 Ball End Mill 0.0156 in 3 Flute Carbide

Product Description

The ACCUPRO 14881901 is a miniature solid carbide ball end mill designed for precision milling in tight-tolerance applications. With a 0.0156 inch (1/64 inch) mill diameter and a 0.022 inch length of cut, this tool is built for fine detail work in hardened steels, stainless, titanium, and non-ferrous alloys. The three-flute geometry balances chip evacuation with cutting edge strength at small diameters. An AlTiN coating provides thermal resistance and extended tool life under demanding cutting conditions. Machinists and toolroom operators working on mold cavities, micro-features, and intricate contoured surfaces will find this tool well suited to the task.

This end mill is used in CNC machining centers and high-speed spindle setups where small-diameter, high-precision cuts are required. The miniature series designation indicates it is intended for micro-milling applications in production and prototype environments. The 1/8 inch shank diameter is a standard size compatible with collet systems commonly used for small-diameter tooling. The single-end configuration and extended reach design make it effective for accessing recessed geometry and pocket floors with limited clearance.

Key Features

• 0.0156 inch (1/64 inch) ball mill diameter for micro-scale cutting operations
• 3-flute design balances chip clearance and rigidity at small diameters
• AlTiN coating enhances heat resistance and extends tool life in ferrous and exotic alloys
• 30-degree helix angle with right-hand cut and right-hand spiral flute direction
• Extended reach geometry allows access to deep or recessed features
• Micrograin solid carbide substrate supports tight tolerances and fine surface finishes

Compatibility

Designed as a miniature series replacement-grade solid carbide ball end mill compatible with 1/8 inch collet holders and standard CNC tooling systems accepting that shank diameter.

Installation Notes

Installation should be performed by a qualified machinist following standard CNC tooling setup procedures. Ensure the spindle is fully stopped and locked out before loading or changing tooling. Verify collet condition and runout before securing the shank to avoid premature wear at this diameter. Consult machine tool specifications and cutting data tables for appropriate speeds and feeds for the workpiece material.
