Accupro A-6120232R Micro Drill Bit 2.32 Mm Solid Carbide

Product Description

The ACCUPRO A-6120232R is a solid carbide micro drill bit designed for precision drilling in tight tolerances and small-diameter applications. Built to the Miniature series standard, it features a 2.32 mm cutting diameter, a 120-degree point angle, and a spiral flute geometry that promotes efficient chip evacuation. The bright, uncoated finish leaves the carbide substrate exposed for maximum hardness and heat resistance. With an overall length of 38 mm and a 3 mm straight-cylindrical shank, this bit seats securely in standard collets and chucks. It is suited for machinists, tool and die makers, and precision fabricators working with small-bore requirements.

This micro drill bit is used in precision machining environments where small-diameter holes are required in materials such as steel, aluminum, plastics, and composites. The 0.0913 inch decimal equivalent makes it a useful reference for shops working in mixed measurement systems. The 12 mm flute length provides adequate cutting depth for most through-hole and blind-hole applications in the Miniature series range. It is well-suited for CNC machining centers, drill presses, and manual milling setups where collet runout and spindle concentricity are controlled.

Key Features

• 2.32 mm cutting diameter with 0.0913 inch decimal equivalent for dual-measurement reference
• 120-degree standard point angle for accurate self-starting entry
• Solid carbide construction for high hardness and wear resistance
• Bright, uncoated finish preserves substrate integrity without coating buildup
• Spiral flute design promotes chip clearance during drilling
• 3 mm straight-cylindrical shank for compatibility with standard collets and chucks

Compatibility

Designed as an OEM-style Miniature series micro drill bit compatible with standard collet and chuck systems accepting a 3 mm straight-cylindrical shank.

Installation Notes

Installation and use should be performed by qualified machinists familiar with small-diameter tooling practices. Secure the shank fully in the collet and verify runout before drilling to prevent bit deflection or breakage. Reduce feed rate and spindle speed incrementally when drilling hard materials to extend tool life. Inspect the cutting edges under magnification before each use, as micro drill bits are susceptible to chipping that is not visible to the naked eye.
