The ACCUPRO A-6120233R is a solid carbide micro drill bit designed for precision drilling in tight-tolerance applications. It measures 2.33 mm (0.0917 inches) in diameter with an overall length of 38 mm (1.496 inches) and a flute length of 12 mm (0.472 inches). The 120-degree standard point angle provides accurate entry and reduces walking on hard or smooth surfaces. Solid carbide construction delivers the rigidity and wear resistance needed for consistent hole quality in demanding materials. The bright, uncoated finish makes it well-suited for use in non-ferrous metals, plastics, composites, and similar materials where coating buildup is a concern.
This micro drill bit belongs to the Miniature series and is intended for applications requiring small-diameter holes with close dimensional tolerances. Typical use cases include PCB drilling, instrument manufacturing, mold and die work, and small-part fabrication in machine shops. The straight-cylindrical shank with a 3 mm diameter seats securely in standard collet chucks and drill chucks sized for metric micro tooling. Right-hand spiral flutes evacuate chips efficiently during through-hole and blind-hole operations.
Designed as an OEM-style replacement or direct tooling option for CNC machining centers, drill presses, and hand-held pneumatic or electric drilling equipment accepting a 3 mm straight-cylindrical shank in the Miniature series micro drill category.
Installation should be performed by a qualified machinist or tool-and-die technician. Power down and lock out the machine spindle before loading or changing tooling. Seat the shank fully and evenly in the collet or chuck before tightening to manufacturer specifications. Micro carbide drills are brittle — avoid side loading, excessive feed pressure, or use in hand-held free-form drilling, as these conditions increase the risk of breakage.
