Accupro A-6100070R Micro Drill Bit 0.7 Mm Solid Carbide

Product Description

The ACCUPRO A-6100070R is a solid carbide micro drill bit designed for precision drilling in small-diameter applications. With a 0.7 mm cutting diameter (0.0276 inches) and a 120-degree standard point angle, this bit delivers accurate hole entry and clean breakthrough in tight-tolerance work. The bright, uncoated finish is suited for a range of base materials where coating is not required. At 30 mm overall length with a 5.60 mm flute length, this miniature-series drill is built for controlled, shallow-depth micro drilling where rigidity and concentricity matter. It is installed and used by machinists, toolmakers, and precision fabricators working in electronics, medical, and instrument manufacturing environments.

This bit fits precision drilling operations requiring small-diameter, high-accuracy holes. The straight-cylindrical shank at 1.50 mm diameter seats securely in standard collet chucks and micro drill chucks used on CNC machining centers, drill presses, and precision hand-held equipment. Regular spiral fluting promotes chip evacuation in short-flute micro drilling scenarios. The miniature series designation indicates this bit is intended for fine-detail and instrument-class work rather than general production drilling. No coolant-through capability is present, so external cooling or dry drilling techniques apply.

Key Features

• 0.7 mm cutting diameter (0.0276 inches) for precision micro-hole applications
• Solid carbide construction provides rigidity and wear resistance in hard and abrasive materials
• 120-degree standard point angle for accurate self-centering on entry
• Bright, uncoated finish suitable for dry or externally cooled drilling
• Right-hand cut, regular spiral flute for controlled chip removal
• 1.50 mm straight-cylindrical shank for compatibility with standard micro collet chucks

Compatibility

Designed as an OEM-style miniature drill bit for use in standard micro collet chucks and precision drill holders accepting a 1.50 mm straight-cylindrical shank.

Installation Notes

Installation is performed by machinists and toolroom technicians using collet chucks or precision drill holders rated for 1.50 mm shank diameters. Secure the shank fully within the collet and verify runout before drilling to prevent bit deflection or breakage at this diameter. Power down and de-energize the spindle before bit changes. No coolant-through channel is present; use external mist cooling or dry drilling as appropriate for the workpiece material.
