Accupro A-6100199R No. 47 Micro Drill Bit Solid Carbide

Product Description

The ACCUPRO A-6100199R is a solid carbide micro drill bit in the Miniature series, designed for precision drilling in tight-tolerance applications. It carries a wire gauge size of No. 47, equivalent to 1.99 mm (0.0783 inches) in diameter, and features a 120-degree standard point angle for clean entry and accurate hole location. The bright, uncoated finish preserves sharp cutting edges out of the box. With a right-hand spiral flute and a straight-cylindrical shank, this bit is suited for machinists, toolmakers, and precision fabricators working on small-diameter through-holes in metal, plastic, and composite materials.

This micro drill bit is used in CNC machining centers, drill presses, and manual spindles where small-diameter, high-precision holes are required. The 12.00 mm flute length provides adequate chip evacuation for shallow to moderate depth holes typical in miniature component work. The 2.00 mm straight-cylindrical shank fits standard collets and chucks without modification. It is a single-unit package sized for bench stock or individual job use.

Key Features

• No. 47 wire size: 1.99 mm diameter for tight-tolerance small-hole drilling
• 120-degree standard point angle for accurate self-centering entry
• Solid carbide construction for rigidity and wear resistance in hard materials
• Bright, uncoated finish preserves edge sharpness without coating buildup
• Right-hand spiral flute promotes efficient chip evacuation
• Straight-cylindrical 2.00 mm shank fits standard collets and precision chucks

Compatibility

Designed as an OEM-style replacement or stock drill bit for miniature-series tooling setups requiring a No. 47 wire gauge diameter with a straight-cylindrical shank and 120-degree point geometry.

Installation Notes

Installation is performed by machinists or toolroom personnel using standard collet or drill chuck setups. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Secure the shank fully within the collet or chuck to the minimum engagement depth recommended for the holder type. Avoid side-loading micro drill bits, as solid carbide is rigid but brittle under lateral force.
