Accupro 12465455 Ball End Mill 0.028 in 2 Flute Carbide

Product Description

The ACCUPRO 12465455 is a miniature solid carbide ball end mill designed for precision milling of small features, contours, and complex 3D profiles. With a 0.028-inch cutting diameter and a 0.042-inch length of cut, this tool is purpose-built for tight-tolerance work in die-making, mold finishing, and micro-machining applications. The two-flute, right-hand spiral geometry with a 30-degree helix angle promotes efficient chip evacuation at high spindle speeds. The micrograin carbide substrate delivers the rigidity and edge retention required for consistent performance on ferrous and non-ferrous materials alike. The uncoated finish makes it suitable for use with cutting fluids where coating adhesion or heat buildup would otherwise be a concern.

This miniature ball end mill is used in CNC machining centers and high-speed spindle setups for detail work on molds, dies, and precision components. The stub-length configuration provides added rigidity, reducing deflection during fine finish passes. It is a single-end tool, appropriate for close-quarter work where a compact overhang is critical. Typical users include tool-and-die makers, mold machinists, and precision CNC operators working on parts requiring fine surface finish and accurate profile geometry.

Key Features

• 0.028-inch ball nose diameter for fine detail and small-radius contour milling
• Micrograin solid carbide construction for edge retention and rigidity in hard materials
• 2-flute, right-hand spiral with 30-degree helix for efficient chip flow at elevated RPM
• Stub-length design minimizes deflection during high-precision finish passes
• Uncoated surface compatible with coolant-assisted cutting strategies
• Single-end configuration sized for miniature and micro-machining setups

Compatibility

Designed as an OEM-style miniature ball end mill for use in CNC machining centers and high-speed spindle units accepting a 0.125-inch (1/8-inch) straight shank.

Installation Notes

Installation should be performed by a qualified CNC machinist or tooling technician. Ensure the spindle is fully powered down and at rest before inserting or removing the tool from the collet or tool holder. Use a properly sized collet to match the 0.125-inch shank diameter and verify runout with a dial indicator before beginning a cut. Do not exceed the manufacturer-recommended feed and speed parameters for the workpiece material and machine spindle rating.
