Accupro A-6120204R Micro Drill Bit 2.04 Mm Solid Carbide

Product Description

The ACCUPRO A-6120204R is a solid carbide micro drill bit designed for precision drilling in tight-tolerance applications. It measures 2.04 mm in diameter (0.0803 inches) with an overall length of 38 mm (approximately 1.50 inches) and a flute length of 12 mm (approximately 0.47 inches). The 120-degree point angle and spiral flute geometry promote clean entry and efficient chip evacuation. The bright, uncoated finish leaves the carbide substrate exposed, making it suitable for applications where coating buildup could affect hole diameter accuracy. Machinists, toolmakers, and precision fabricators typically select this bit for small-diameter work in ferrous and non-ferrous materials.

This micro drill bit is intended for small-hole drilling operations where standard-size bits are too large. The 3.00 mm straight-cylindrical shank fits conventional collet chucks and drill chucks sized for miniature tooling. Right-hand cutting direction suits standard CNC machining centers, drill presses, and hand-held precision drilling equipment. It is part of the ACCUPRO Miniature series, which targets applications in electronics manufacturing, medical device machining, aerospace component work, and precision instrument fabrication where hole diameters in the sub-3 mm range are common.

Key Features

• 2.04 mm diameter with 120-degree standard point for accurate hole entry
• Solid carbide construction provides rigidity and wear resistance at small diameters
• Spiral flute design promotes chip clearance in deep or interrupted cuts
• Bright/uncoated finish maintains true cutting diameter without coating variance
• 3.00 mm straight-cylindrical shank compatible with standard miniature collet systems
• Right-hand cut suits conventional machine spindle rotation

Compatibility

Designed for use in CNC machining centers, benchtop drill presses, and precision hand drilling equipment accepting a 3.00 mm straight-cylindrical shank. Part of the ACCUPRO Miniature series for sub-3 mm diameter drilling applications.

Installation Notes

Installation and use should be performed by qualified machinists or toolroom personnel familiar with small-diameter tooling. Secure the shank fully in the collet or chuck before operation and verify runout before drilling to avoid bit deflection or breakage at this diameter. Reduce feed rate and spindle speed relative to standard drill bits of the same material class, as micro-diameter carbide tools are sensitive to side loading. Always wear appropriate eye protection and follow shop safety protocols when handling and operating carbide cutting tools.
