Accupro A-6200180R 1.8 Mm Solid Carbide Micro Drill Bit

Product Description

The ACCUPRO A-6200180R is a solid carbide micro drill bit designed for precision drilling in tight-tolerance applications. It measures 1.8 mm (0.0709 inches) in diameter with a 50 mm overall length and a 13 mm flute length. The 140-degree point angle promotes accurate entry and reduces walking on hard or dense materials. The bright, uncoated finish is suited for use on non-ferrous metals, plastics, composites, and other materials where coating build-up would reduce hole quality. Right-hand spiral flutes evacuate chips efficiently during drilling. This bit is sold individually and is intended for use by machinists, tool-and-die professionals, and precision fabricators working on small-diameter through-holes.

This micro drill bit is part of the ACCUPRO Miniature series, designed for applications where standard-diameter bits are too large. Typical use cases include printed circuit board drilling, instrument manufacturing, medical device fabrication, watchmaking, jewelry work, and fine metalworking. The straight-cylindrical shank at 3.0 mm diameter fits collet-style chucks and precision drill press spindles commonly used in high-accuracy operations. It is well suited to CNC drilling centers and benchtop precision presses operating at high RPM with low feed rates.

Key Features

• 1.8 mm (0.0709 inches) cutting diameter for precision micro-hole applications
• Solid carbide construction for rigidity and wear resistance in hard or abrasive materials
• 140-degree standard point angle reduces thrust force and improves entry accuracy
• Bright, uncoated finish suitable for non-ferrous metals, plastics, and composites
• Right-hand spiral flute design promotes consistent chip evacuation
• 3.0 mm straight-cylindrical shank fits standard collet and precision chuck systems

Compatibility

Designed as a miniature-series replacement or stock drill bit for precision drilling operations requiring a 1.8 mm diameter cutting tool with a 3.0 mm straight-cylindrical shank.

Installation Notes

Micro drill bits of this diameter require a high-speed, low-vibration spindle and a precision collet chuck to avoid runout-induced breakage. Secure the shank fully in the collet before operation and confirm concentricity before drilling. Do not apply excessive feed pressure; micro carbide bits are brittle and will snap under lateral load or side force. Always wear eye protection and follow applicable shop safety procedures when operating drilling equipment.
