Accupro 14797494 Ball End Mill 0.02in 4 Flute Solid Carbide

Product Description

The ACCUPRO 14797494 is a miniature ball end mill designed for precision milling of small features, contours, and complex geometries in tight tolerances. Ground from solid micrograin carbide, this 4-flute tool measures 0.02 inches in diameter with a 0.06-inch length of cut and a 1.5-inch overall length. The 30-degree right-hand helix promotes efficient chip evacuation while maintaining surface finish quality. With an extended reach configuration and a 0.17-inch neck length, it is suited for machining recessed areas and fine detail work that standard end mills cannot access. Machinists and tool-and-die professionals working on CNC milling machines install this tool for finishing passes on small cavities, slots, and 3D surfaces.

This end mill is intended for use in CNC machining centers and manual mills where small-feature milling is required. The miniature series designation makes it appropriate for work in mold-making, medical device machining, aerospace components, and precision instrument manufacturing. The 1/8-inch shank diameter fits standard collets and tool holders commonly found in vertical machining centers handling small-part work. The uncoated solid carbide construction is suitable for a range of non-ferrous metals, hardened steels, and engineering plastics depending on operating parameters.

Key Features

• Solid micrograin carbide construction for superior rigidity and wear resistance at small diameters
• 4-flute geometry supports improved surface finish on finishing passes
• 30-degree right-hand helix for effective chip flow in small-feature milling
• Extended reach design with 0.17-inch neck length for access to recessed areas
• Single-end configuration with right-hand cutting direction
• Miniature series with tight diameter tolerance of +0.0000 to -0.0010 inches for precision fitment

Compatibility

Designed as an OEM-style replacement and standard tooling option for CNC machining centers and manual mills equipped with 1/8-inch collets or tool holders accepting miniature-series end mills.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer guidelines. Ensure the spindle is fully stopped and the machine is locked out before changing tooling. Seat the 1/8-inch shank fully into a clean, undamaged collet and torque the collet nut to the tool holder specification. At 0.02 inches in diameter, this tool is extremely fragile — verify runout with an indicator before cutting and start with conservative feed and speed parameters to avoid breakage.
