Accupro A-6100180R Micro Drill Bit 1.8 Mm Solid Carbide

Product Description

The ACCUPRO A-6100180R is a solid carbide micro drill bit designed for precision drilling in tight-tolerance applications. It measures 1.8 mm in diameter (0.0709 inches) with an overall length of 38 mm (approximately 1.5 inches) and a flute length of 12 mm (approximately 0.47 inches). The 120-degree standard point angle and spiral flute geometry support accurate entry and efficient chip evacuation. The bright, uncoated finish is suited for use in materials where coating adhesion or heat buildup is not a primary concern. Machinists, toolmakers, and precision fabricators install this bit in CNC machines, drill presses, and high-speed hand tools where small-diameter accuracy is critical.

This micro drill bit is intended for small-diameter drilling operations in precision machining environments. The straight-cylindrical shank with a 2 mm diameter fits standard collets and chuck systems used in miniature drilling setups. Its right-hand cutting direction suits conventional drilling operations on metals, composites, and similar materials requiring tight hole tolerances. The miniature series designation indicates suitability for fine work where standard-sized bits would be impractical.

Key Features

• 1.8 mm drill diameter with 0.0709 inch decimal equivalent for precise hole sizing
• Solid carbide construction for rigidity and wear resistance in hard materials
• 120-degree standard point angle for accurate self-centering on entry
• Spiral flute design promotes chip removal during drilling
• Bright uncoated finish compatible with a wide range of materials
• Straight-cylindrical 2 mm shank fits standard collet and chuck systems

Compatibility

Designed as an OEM-style replacement or direct-use micro drill bit for miniature series drilling applications requiring a 1.8 mm diameter solid carbide bit with a straight-cylindrical shank.

Installation Notes

This bit is installed by qualified machinists or toolroom technicians in CNC machining centers, benchtop drill presses, or precision hand-held drilling equipment. Ensure the spindle and collet or chuck are fully powered down and at rest before securing the bit. Confirm the 2 mm shank seats fully and is clamped to the tool manufacturer's specified holding depth. Avoid side-loading or using the bit beyond its rated diameter capacity, as solid carbide is brittle and susceptible to breakage under off-axis stress.
