Accupro 12465459 Ball End Mill 0.03 in 2 Flute Carbide

Product Description

The ACCUPRO 12465459 is a miniature solid carbide ball end mill designed for precision milling operations in tight geometries and small-feature work. The 0.03-inch cutting diameter and 0.045-inch length of cut make it well-suited for contouring, profiling, and finishing passes where space is constrained and accuracy is critical. Built from micrograin solid carbide, the tool delivers consistent edge retention at the cutting zone. The bright uncoated finish is standard for this diameter range. With a 30-degree helix angle and right-hand cutting and flute direction, it produces smooth chip evacuation on a wide range of workpiece materials. Licensed machinists and toolmakers are the typical end users.

This end mill fits applications in mold and die machining, medical component manufacturing, aerospace detail work, and precision prototype fabrication. The stub length-of-cut designation keeps deflection low when working in shallow pockets or engraving fine contours. The 1/8-inch shank diameter allows use in standard collet chucks, end mill holders, and precision tool holders commonly found on CNC mills and machining centers. It is a single-end tool intended for single-use orientation.

Key Features

• Micrograin solid carbide construction for edge stability at miniature diameters
• 0.03-inch ball nose diameter for fine-detail contouring and small-radius profiling
• 30-degree helix angle with right-hand spiral flutes for smooth chip flow
• Bright uncoated finish suitable for a broad range of base materials
• 1/8-inch shank diameter fits standard collet and end mill holder systems
• Stub length of cut minimizes deflection in shallow, precision passes

Compatibility

Designed as a direct-fit miniature ball end mill for CNC machining centers and manual mills equipped with 1/8-inch collet or tool holder systems requiring a single-end ball nose geometry.

Installation Notes

Installation and tool changes should be performed with the spindle fully stopped and the machine in a locked-out state per shop safety procedures. Seat the 1/8-inch shank fully into the collet or holder before tightening to the manufacturer-specified torque for that holder type. Inspect the cutting edges under magnification before use, as chips or micro-fractures at this diameter may not be visible to the naked eye. Handle miniature carbide tooling with care — carbide is brittle and can fracture if dropped or impacted.
