Accupro A-6120199R Micro Drill Bit 1.99mm Solid Carbide

Product Description

The ACCUPRO A-6120199R is a solid carbide micro drill bit designed for precision drilling in tight-tolerance applications. It measures 1.99 mm (0.0783 inches) in diameter with a 120-degree drill point angle, making it well suited for clean entry in hard or abrasive materials. The bright, uncoated finish and spiral flute geometry promote efficient chip evacuation during high-speed drilling operations. With an overall length of 38.00 mm and a straight cylindrical shank, this bit seats securely in standard collet chucks and drill chucks used in machining centers, CNC mills, and precision drill presses.

This micro drill bit is intended for machinists, tool-and-die makers, and precision fabricators working in metalworking, electronics manufacturing, mold-making, and similar industries where small-diameter hole accuracy is critical. The miniature series designation indicates suitability for fine-detail work where standard jobber-length bits are too large or too long. It is a single-piece unit sold individually, with a minimum order quantity of 10 pieces per order.

Key Features

• 1.99 mm (0.0783 inches) cutting diameter for precise micro-hole applications
• 120-degree standard point angle for accurate self-centering entry
• Solid carbide construction for rigidity and wear resistance in hard materials
• Bright, uncoated finish compatible with a wide range of workpiece materials
• Spiral flute with regular spiral type promotes consistent chip evacuation
• Straight cylindrical shank for reliable seating in collet and drill chuck systems

Compatibility

Designed as a miniature-series replacement or stock drill bit for CNC machining centers, precision drill presses, and benchtop drilling setups that accept a 2.00 mm straight cylindrical shank and require a 1.99 mm cutting diameter.

Installation Notes

Installation and use of micro drill bits should be performed by qualified machinists familiar with proper toolholding and runout specifications for small-diameter tooling. Ensure the spindle and collet or chuck are clean and free of debris before seating the shank to prevent runout that can snap small-diameter carbide bits. Always verify spindle speed and feed rate settings against the material being drilled before starting the cut. Carbide is brittle and can fracture if subjected to lateral loading or dropped on hard surfaces.
