Accupro A-6120271R Micro Drill Bit 2.71 Mm Solid Carbide

Product Description

The ACCUPRO A-6120271R is a solid carbide micro drill bit designed for small-diameter precision drilling in tight-tolerance applications. Built to the miniature series standard, it measures 2.71 mm (0.1067 inches) in diameter with a 38 mm overall length and a 14 mm flute length. The 120-degree point angle and spiral flute geometry promote clean entry and efficient chip evacuation. The bright, uncoated finish keeps the surface at a true dimension and suits use across a range of workpiece materials. This bit is installed by machinists, tool-and-die technicians, and precision fabricators working in production or maintenance environments.

This drill bit fits applications requiring fine-diameter holes in metal, plastics, or composite materials. The straight-cylindrical shank measures 3.00 mm in diameter, making it compatible with standard collet chucks and drill chucks that accept that shank size. Right-hand cutting direction is standard for conventional CNC machining centers, drill presses, and hand-held precision drilling equipment. It is well suited for PCB work, instrument manufacturing, mold making, and similar precision machining tasks where hole diameter consistency is critical.

Key Features

• 2.71 mm (0.1067 inches) drill diameter for tight-tolerance small-hole work
• Solid carbide construction for rigidity and wear resistance in precision applications
• 120-degree standard point angle for accurate centering and clean entry
• Spiral flute design promotes chip evacuation during drilling
• Bright, uncoated finish — no coating buildup to affect hole diameter
• 3.00 mm straight-cylindrical shank fits standard collet and drill chucks

Compatibility

Designed for use with collet chucks, keyless drill chucks, or drill press spindles accepting a 3.00 mm straight-cylindrical shank; suitable for CNC machining centers, drill presses, and precision hand-drilling equipment.

Installation Notes

Installation and use should be performed by qualified machinists or precision fabricators. Secure the shank fully in the chuck and verify runout before drilling. Ensure spindle speed is appropriate for the workpiece material and drill diameter before engaging the cut. Do not exceed the rated diameter by reaming with this bit, and avoid side-loading the flute, which can cause breakage in small-diameter carbide tooling.
