Accupro A-6120200R Micro Drill Bit 2mm Solid Carbide

Product Description

The ACCUPRO A-6120200R is a solid carbide micro drill bit engineered for precision drilling in miniature and close-tolerance applications. Built to a 2 mm diameter with a 120-degree point angle and a straight-cylindrical shank, this bit delivers accurate entry and consistent hole geometry in hard and abrasive materials. The bright, uncoated carbide construction provides a sharp cutting edge straight out of the package. With a 38 mm overall length and a 12 mm flute length, it fits compact toolholding setups where reach and rigidity both matter. Right-hand spiral flutes evacuate chips efficiently during the cut. Licensed machinists, tool-and-die makers, and precision CNC operators are the primary users.

This bit is suited for drilling small-diameter holes in ferrous and non-ferrous metals, printed circuit board materials, plastics, and composite substrates. Its miniature-series designation makes it appropriate for CNC machining centers, drill presses, and bench-top equipment configured for high-speed micro drilling. The 3 mm shank diameter allows seating in standard collets and chucks sized for miniature tooling. Applications span aerospace component work, electronics manufacturing, mold and die detail work, and precision fabrication shops where hole diameter tolerance is critical.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard materials
• 120-degree point angle for accurate, self-centering entry on small-diameter holes
• Bright, uncoated finish — ready to use without additional surface treatment
• Right-hand cut with regular spiral flutes for efficient chip evacuation
• Straight-cylindrical 3 mm shank seats securely in standard miniature collets and chucks
• Miniature series sizing optimized for high-speed, close-tolerance drilling operations

Compatibility

Designed as a miniature-series replacement or production drill bit for CNC machining centers, drill presses, and precision benchtop equipment configured to accept a 3 mm straight-cylindrical shank with collet or chuck toolholding.

Installation Notes

Installation and use should be performed by machinists or qualified shop personnel familiar with CNC or manual drilling equipment. Secure the shank fully in a properly sized collet or drill chuck before running the spindle. Inspect the cutting edges for chips or wear before each use, as micro drill bits are sensitive to edge damage at small diameters. Follow machine manufacturer guidelines for spindle speed and feed rate when working at 2 mm diameter to avoid bit breakage.
