Accupro A-6100168R Micro Drill Bit 1.68 Mm Solid Carbide

Product Description

The ACCUPRO A-6100168R is a solid carbide micro drill bit designed for precision drilling in miniature and tight-tolerance applications. With a diameter of 1.68 mm (0.0661 inches) and an overall length of 38.00 mm, this bit delivers consistent performance where accuracy is critical. The 120-degree drill point angle and spiral flute geometry promote clean chip evacuation and stable entry into the workpiece. The bright/uncoated finish indicates an unaltered carbide substrate, suitable for use in a range of materials where coating interaction is a concern. This tool is used by machinists, toolmakers, and precision fabricators working on small-diameter hole requirements.

This micro drill bit fits into miniature-series drilling operations found in precision machining, electronics manufacturing, medical device fabrication, and fine mechanical assembly. The straight-cylindrical shank with a 2.00 mm diameter seats securely in standard collets and chucks compatible with that shank size. Right-hand cutting direction is standard for conventional CNC machining centers, manual drill presses, and micro-drilling fixtures where left-hand spindle operation is not required. The 12.00 mm flute length provides adequate depth capacity for typical micro-drilling passes in this size range.

Key Features

• Solid carbide construction for rigidity and wear resistance in precision drilling
• 1.68 mm (0.0661 inches) diameter for tight-tolerance, small-diameter holes
• 120-degree standard point angle for stable, accurate drill entry
• Spiral flute type with regular spiral for consistent chip evacuation
• Bright/uncoated finish — no coating interaction with workpiece material
• Straight-cylindrical shank fits standard collets and chucks accepting 2.00 mm shanks

Compatibility

Designed as a miniature-series replacement or working drill bit for CNC machining centers, micro-drilling stations, and precision drill presses equipped with collets or chucks that accept a 2.00 mm straight-cylindrical shank.

Installation Notes

Installation and operation should be performed by qualified machinists or toolroom technicians familiar with micro-drilling procedures. Ensure the machine spindle is fully stopped and locked out before inserting or removing the bit from the collet or chuck. Verify collet or chuck concentricity before running at speed, as runout at this diameter can cause premature breakage. Follow machine manufacturer feed and speed guidelines for solid carbide tooling at this diameter range.
