Accupro 14881959 Ball End Mill 3/64 in 3 Flute Solid Carbide

Product Description

The ACCUPRO 14881959 is a miniature ball end mill designed for precision milling operations in tight geometries and fine-detail work. Built from micrograin solid carbide, this single-end tool features a 3/64 inch (0.0469 inch decimal) cutting diameter with a 0.0700 inch length of cut and a 30-degree helix angle. The three-flute spiral configuration promotes efficient chip evacuation while maintaining a stable cutting edge at small diameters. The bright/uncoated finish makes it suitable for a range of non-ferrous and ferrous materials where coating adhesion is not required. Machinists and tooling specialists install this end mill in CNC machining centers and high-speed milling applications.

This end mill is suited for small-part machining, mold and die work, engraving, and contour milling where a miniature tool profile is required. The extended-reach design, combined with a 1/4 inch neck length, allows access into deep cavities and recessed features without tool interference. The 1/8 inch shank diameter fits standard collet systems. It is commonly used in job shops, prototype facilities, and production environments where fine detail and tight tolerances are priorities.

Key Features

• Micrograin solid carbide construction for rigidity and wear resistance at small diameters
• 3/64 inch ball diameter with 0.0700 inch length of cut for fine-detail milling
• 3-flute spiral geometry with 30-degree right-hand helix for efficient chip flow
• Extended reach with 1/4 inch neck length for deep-cavity access
• Bright/uncoated finish compatible with a broad range of workpiece materials
• Tight diameter tolerance of +0.0000 / -0.0010 inch for consistent fitment and repeatability

Compatibility

Designed for use in CNC machining centers and milling machines equipped with collet systems accepting a 1/8 inch shank diameter. Part of the ACCUPRO Miniature series for small-diameter precision milling applications.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the 1/8 inch shank fully in the collet to the recommended grip depth before tightening to prevent pullout under cutting loads. Confirm runout with a dial indicator after installation, especially given the small diameter and extended-reach geometry, which amplify the effect of any misalignment.
