Accupro A-6120268R Micro Drill Bit 2.68mm Solid Carbide

Product Description

The ACCUPRO A-6120268R is a solid carbide micro drill bit designed for precision drilling in tight-tolerance applications. It features a 2.68 mm (0.1055 inch) cutting diameter, a 120-degree drill point angle, and a 38.00 mm overall length. The straight-cylindrical shank measures 3.00 mm in diameter, providing secure chuck engagement. The bright/uncoated finish is standard for solid carbide tooling where coating is not required by the application. This bit is part of the Miniature Series and is intended for use by machinists, tool-and-die professionals, and precision fabricators working with small-diameter hole requirements.

This micro drill bit is suited for small-diameter drilling in materials where solid carbide offers a rigidity and wear-resistance advantage over high-speed steel. Typical applications include precision machining of metal components, circuit board fabrication support fixtures, and miniature mechanical assemblies requiring consistent hole geometry. The right-hand cutting direction and spiral flute design promote efficient chip evacuation during through-hole and blind-hole operations in ferrous and non-ferrous materials.

Key Features

• Solid carbide construction provides rigidity and extended tool life in precision drilling applications
• 2.68 mm (0.1055 inch) cutting diameter with a 120-degree standard point angle
• 38.00 mm overall length with a 14.00 mm flute length for small-diameter reach
• 3.00 mm straight-cylindrical shank for compatibility with standard collet chucks and drill chucks
• Bright/uncoated finish — suitable for applications where coated tooling is not specified
• Regular spiral, right-hand cut with spiral flutes for consistent chip removal

Compatibility

Designed as a miniature-series solid carbide drill bit for use in CNC machining centers, drill presses, and precision hand tools equipped with a chuck or collet accepting a 3.00 mm straight-cylindrical shank.

Installation Notes

Install and remove tooling only when the spindle is fully stopped and the machine is powered down or in a safe locked-out state per facility LOTO procedures. Verify chuck or collet runout before use — micro drill bits are sensitive to runout-induced breakage at small diameters. Do not exceed the recommended feed rate and spindle speed for the workpiece material and this diameter. Coolant-through is not supported on this bit; apply external coolant or cutting fluid as appropriate for the material.
