Accupro A-6100194R Micro Drill Bit 1.94 Mm Solid Carbide

Product Description

The ACCUPRO A-6100194R is a solid carbide micro drill bit designed for precision drilling in tight-tolerance applications. It features a 1.94 mm cutting diameter, a 120-degree standard point angle, and a bright uncoated finish that suits a wide range of base materials. The right-hand spiral flute design promotes efficient chip evacuation during drilling. With an overall length of 38 mm and a 2.00 mm straight-cylindrical shank, this bit fits standard collet chucks and precision drill holders. Machinists, toolmakers, and CNC operators working in manufacturing, electronics, and aerospace applications rely on solid carbide construction for rigidity and wear resistance at small diameters.

This micro drill bit is suited for precision drilling operations in ferrous and non-ferrous metals, plastics, and composites where small hole diameters are required. The miniature series designation indicates it is engineered for close-tolerance work typical in printed circuit board fabrication, instrument components, and small-part machining. The 12 mm flute length provides adequate chip clearance while maintaining bit rigidity at this diameter. It is sold individually per package with a minimum order quantity of 10 units.

Key Features

• Solid carbide construction for maximum rigidity and wear resistance at micro diameters
• 1.94 mm cutting diameter with 0.0764 inch decimal equivalent
• 120-degree standard point angle for accurate entry and reduced walking
• Right-hand cut with regular spiral flute for efficient chip evacuation
• Bright uncoated finish compatible with a broad range of workpiece materials
• Straight-cylindrical shank at 2.00 mm for secure collet or chuck retention

Compatibility

Designed for use in CNC machining centers, precision drill presses, and manual spindles equipped with collet chucks or drill holders accepting a 2.00 mm straight-cylindrical shank.

Installation Notes

Installation and use should be performed by qualified machinists or CNC operators. Ensure the spindle and work holding are powered down and secured before bit changes. Use a properly sized collet to match the 2.00 mm shank diameter and verify runout with a dial indicator before production drilling. Avoid side-loading micro-diameter carbide bits, as the small cross-section is susceptible to breakage under lateral force.
