Accupro 12465414 Ball End Mill 0.01 in 2 Flute Solid Carbide

Product Description

The ACCUPRO 12465414 is a miniature solid carbide ball end mill designed for precision milling operations requiring tight tolerances and fine detail work. With a 0.01 inch cutting diameter and a 0.015 inch length of cut, this single-end tool is built for small-feature machining in hardened and abrasive materials. The micrograin carbide substrate provides the edge retention and rigidity needed at this scale. The 30-degree right-hand spiral helix promotes efficient chip evacuation, reducing heat buildup and deflection in delicate passes. Machinists and toolroom professionals typically select this tool for engraving, slotting, and contour work where standard tooling is too large.

This end mill is suited for use in CNC machining centers, high-speed spindles, and precision manual mills capable of holding tight runout tolerances. Its stub length classification and 1/8 inch shank diameter make it compatible with standard collet systems in that range. Applications include mold and die work, medical component machining, jewelry tooling, and micro-feature profiling. The bright, uncoated finish makes it appropriate for non-ferrous materials, plastics, and finishing passes where coating buildup at the cutting edge could affect accuracy.

Key Features

• 0.01 inch ball nose diameter with a mill diameter tolerance of +0.0000 to -0.0010 inches for precise feature sizing
• Micrograin solid carbide construction for improved hardness and edge retention at miniature scale
• 30-degree right-hand spiral flute geometry promotes chip evacuation in shallow pockets and slots
• Bright, uncoated finish suitable for non-ferrous metals, plastics, and fine finishing applications
• 1/8 inch shank with a tolerance of -0.0001 to -0.0003 inches for consistent collet grip
• Single-end, stub-length configuration provides rigidity in short-reach micro-milling setups

Compatibility

Designed as an OEM-style replacement or direct-use miniature ball end mill for CNC and manual milling setups accepting a 1/8 inch shank collet. No specific machine model compatibility was provided in the product data.

Installation Notes

Installation should be performed by a qualified machinist familiar with micro-tooling handling practices. Power down and lock out the spindle before loading or removing the tool. Use a clean, undamaged 1/8 inch collet and collet nut to ensure proper seating and runout control, as even minor contamination or collet wear can cause premature tool failure at this diameter. Avoid over-torquing the collet nut, and verify runout with a dial indicator before running production cuts.
