Accupro A-6120182R Micro Drill Bit 1.82 Mm Solid Carbide

Product Description

The ACCUPRO A-6120182R is a solid carbide micro drill bit designed for precision drilling in small-diameter applications. It measures 1.82 mm (0.0717 inches) in diameter with a 120-degree point angle and a 38 mm overall length. The straight-cylindrical shank seats at 2.00 mm for consistent chuck engagement. Solid carbide construction provides the rigidity needed to hold tight tolerances at small diameters, where high-speed steel bits tend to deflect or wander. The bright, uncoated finish keeps the surface as-ground, which is typical for carbide tooling used in lower-temperature cutting operations.

This bit is suited for machinists, toolmakers, and precision fabricators working in materials that require a sharp, rigid cutting edge at sub-2 mm diameters. Common applications include PCB drilling, instrument component machining, mold and die work, and watch or medical-device part manufacturing. The spiral flute design promotes chip evacuation in shallow-to-moderate-depth holes. Right-hand cut geometry is standard for conventional CNC machining center and drill press setups.

Key Features

• Solid carbide construction for rigidity and wear resistance at micro diameters
• 1.82 mm drill diameter with 120-degree standard point angle
• 8.40 mm flute length for controlled chip evacuation
• Bright, uncoated finish suitable for dry or light-lubrication cutting
• Straight-cylindrical 2.00 mm shank for standard collet or chuck mounting
• Right-hand, regular spiral flute for compatibility with conventional spindle rotation

Compatibility

Designed for use in CNC machining centers, drill presses, and precision hand-held spindles accepting a 2.00 mm straight-cylindrical shank. Fits standard collets and chucks sized for 2 mm shanks.

Installation Notes

Installation and use should be performed by a qualified machinist or toolroom technician. Ensure the spindle is fully stopped and de-energized before changing tooling. Secure the shank fully within the collet or chuck to the recommended grip depth to prevent runout and bit breakage at this diameter. At sub-2 mm diameters, feed rate and spindle speed selection are critical — consult the machine manufacturer or tooling data charts for the workpiece material before beginning a cut.
