Accupro A-6100167R Micro Drill Bit 1.67mm Solid Carbide

Product Description

The ACCUPRO A-6100167R is a solid carbide micro drill bit designed for precision small-diameter drilling applications. At 1.67 mm (0.0657 inches) in diameter with a 120-degree drill point angle, this bit delivers accurate, clean entry in tight-tolerance work. The overall length is 38.00 mm with a 12.00 mm flute length and a 2.00 mm straight-cylindrical shank. Built from solid carbide with a bright/uncoated finish, it is suited for machinists, toolmakers, and precision fabricators who need consistent performance at the miniature scale. The right-hand cutting direction and spiral flute geometry support controlled chip evacuation during drilling operations.

This micro drill bit is intended for use in CNC machining centers, drill presses, and precision hand-operated spindles where small-diameter hole generation is required. Typical applications include printed circuit board fabrication, instrument components, medical device parts, mold and die work, and other precision manufacturing tasks that demand tight dimensional control. It belongs to the Miniature Series and is sold individually per package, with a minimum order quantity of 10 units.

Key Features

• 1.67 mm (0.0657 inch) drill diameter for micro-scale precision drilling
• 120-degree standard point angle for accurate hole entry and reduced walking
• Solid carbide construction for rigidity and wear resistance at small diameters
• Bright/uncoated finish — compatible with a wide range of cutting fluids and materials
• 12.00 mm spiral flute length promotes chip clearance in deep micro holes
• 2.00 mm straight-cylindrical shank fits standard micro collets and chucks

Compatibility

Designed for use in CNC machining centers, precision drill presses, and spindle setups that accept a 2.00 mm straight-cylindrical shank. Suitable for drilling operations in ferrous and non-ferrous metals, plastics, and composites at the miniature scale.

Installation Notes

Installation and use should be performed by qualified machinists or toolroom technicians. Ensure the machine spindle is fully stopped and locked out before inserting or removing the bit. Secure the 2.00 mm shank firmly in a properly sized collet or drill chuck to prevent runout. Do not exceed the recommended feed rate or spindle speed for the workpiece material, as solid carbide micro drills are brittle and susceptible to breakage under side loading or excessive force.
