Accupro A-6100034R Micro Drill Bit Size 80 Solid Carbide

Product Description

The ACCUPRO A-6100034R is a solid carbide micro drill bit designed for precision drilling in tight-tolerance applications. Built to wire gauge size 80, this bit has a decimal diameter of 0.0134 inches, making it one of the smallest drill sizes used in production and toolroom environments. The 120-degree drill point angle suits general-purpose micro drilling across a range of materials. With a straight-cylindrical shank and right-hand cutting direction, this bit fits standard collet-style and precision drill chucks. It is used by machinists, toolmakers, and precision fabricators working with miniature components, printed circuit boards, and fine detail work.

This bit belongs to the Miniature series and is suited for applications requiring extremely small hole diameters in metal, composite, and similar materials. The solid carbide construction offers the rigidity necessary to maintain accuracy at this diameter, where high-speed steel tooling would deflect or break under normal production conditions. Typical use cases include PCB drilling, watch components, medical device parts, and instrument manufacturing. The bright, uncoated finish keeps the surface geometry consistent and allows visual inspection of the cutting edges between uses.

Key Features

• Wire gauge size 80 with a decimal diameter of 0.0134 inches for ultra-fine hole drilling
• Solid carbide construction provides rigidity and wear resistance at micro diameters
• 120-degree drill point angle for standard-duty micro drilling applications
• Spiral flute geometry with right-hand cutting direction for consistent chip evacuation
• Straight-cylindrical shank with 1.00 mm shank diameter for use in precision collet chucks
• Bright/uncoated finish allows easy edge inspection and suits a broad range of workpiece materials

Compatibility

Designed as an OEM-style replacement or production-grade micro drill bit for use in standard precision collet chucks and drill presses accepting a 1.00 mm straight-cylindrical shank.

Installation Notes

Micro drill bits at this diameter should be installed by a machinist or toolroom technician familiar with high-speed spindle setups. Ensure the collet and chuck are clean and free of debris before seating the shank to avoid runout. Feed rates and spindle speeds must be set conservatively for carbide micro tooling, as side loading or interrupted cuts at this diameter will cause breakage. Follow the machine manufacturer guidelines and applicable shop safety protocols when setting up micro drilling operations.
