Accupro A-6120047R Micro Drill Bit 0.0185 in Solid Carbide

Product Description

The ACCUPRO A-6120047R is a miniature solid carbide micro drill bit designed for precision drilling in small-diameter applications. It features a 0.0185-inch cutting diameter, a 120-degree drill point angle, and a bright/uncoated finish suited for clean, close-tolerance work. The straight-cylindrical shank measures 1.00 mm in diameter, and the overall length is 25.00 mm. Spiral flutes with a regular spiral type promote efficient chip evacuation in tight bores. This bit is intended for machinists, toolmakers, and precision fabricators working with miniature components in metal, plastic, or composite materials.

The A-6120047R is used in CNC machining centers, drill presses, and manual precision drilling setups where small hole diameters are required. Its miniature series classification makes it appropriate for electronics manufacturing, mold and die work, medical device fabrication, and other industries demanding tight tolerances and small feature sizes. The right-hand cutting direction is standard for conventional drilling operations. Coolant-through is not supported on this bit.

Key Features

• 0.0185-inch cutting diameter for micro and miniature bore applications
• Solid carbide construction provides rigidity and wear resistance in hard materials
• 120-degree point angle suits a broad range of workpiece materials
• Spiral flute geometry promotes chip removal in shallow and moderate-depth holes
• Bright/uncoated finish maintains dimensional consistency without coating buildup
• Straight-cylindrical shank compatible with standard collet and chuck systems

Compatibility

Designed as an OEM-style replacement or direct-use miniature drill bit for precision drilling equipment accepting a 1.00 mm straight-cylindrical shank, including CNC machining centers and drill presses using standard collet or chuck tooling.

Installation Notes

This bit should be installed and operated by qualified machinists or toolroom personnel familiar with micro-diameter tooling. Ensure the spindle and collet or chuck are clean and properly sized for the 1.00 mm shank before seating the bit. Micro drill bits are brittle at this diameter — avoid side-loading, excessive feed rates, or re-chucking without inspecting for runout. Refer to the machine manufacturer and applicable shop safety standards for speed and feed recommendations based on workpiece material.
