Accupro A-6120034R Micro Drill Bit Size 80 Solid Carbide

Product Description

The ACCUPRO A-6120034R is a size 80 micro drill bit designed for precision drilling in tight-tolerance applications. Manufactured from solid carbide, it delivers the rigidity and wear resistance required when working at extremely small diameters. The bit measures 0.0134 inches (wire gauge size 80) and features a 120-degree point angle with a standard point type for accurate entry and reduced walking. At 25 mm overall length, it fits standard miniature-series tooling setups used in precision machining, electronics fabrication, and instrumentation work. The spiral flute geometry promotes chip evacuation in shallow-to-moderate depth holes. Installation is handled by machinists and tool-and-die professionals using compatible micro-chuck or collet holders.

This micro drill bit is suited for precision drilling operations in materials where small hole diameters and tight tolerances are required. Typical applications include printed circuit board drilling, instrument components, small-part fabrication, and prototype work. The bright uncoated finish makes it appropriate for non-ferrous metals, plastics, and similar materials where coating adhesion or heat buildup is not a primary concern. The straight-cylindrical shank with a 1.00 mm shank diameter seats securely in precision collet chucks or micro drill presses.

Key Features

• Solid carbide construction for rigidity and extended tool life at micro diameters
• Wire gauge size 80 (0.0134 inches) for ultra-small hole drilling
• 120-degree point angle with standard point type for accurate hole entry
• Spiral flute design promotes chip clearance during drilling
• Bright uncoated finish suitable for non-ferrous and non-abrasive materials
• Straight-cylindrical shank, 1.00 mm diameter, compatible with standard micro collet holders

Compatibility

Designed as an OEM-style miniature series micro drill bit for use in precision collet chucks, micro drill presses, and CNC tooling setups that accept a 1.00 mm straight-cylindrical shank.

Installation Notes

Micro drill bits at this diameter are fragile and should be installed and removed by a qualified machinist or tooling technician using a properly sized precision collet or micro chuck. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Avoid side-loading or flexing the bit during setup, as solid carbide at micro diameters is brittle and susceptible to breakage under lateral stress. Verify runout on the collet or chuck before operation to maintain hole accuracy and extend tool life.
