Accupro A-6100169R Micro Drill Bit 1.69 Mm Solid Carbide

Product Description

The ACCUPRO A-6100169R is a miniature series solid carbide micro drill bit designed for precision drilling in tight-tolerance applications. It features a 1.69 mm (0.0665 inches) drill diameter, a 120-degree drill point angle, and a bright/uncoated finish. The overall length is 38.00 mm, and the shank diameter is 2.00 mm with a straight-cylindrical profile. Made from solid carbide, this bit delivers hardness and rigidity needed to maintain accuracy at small diameters. It is suited for machinists, toolmakers, and precision fabricators working in production or job-shop environments.

This micro drill bit is intended for use in CNC machining centers, drill presses, and precision hand-held drilling equipment where small-diameter, high-accuracy holes are required. The right-hand cutting direction and spiral flute geometry make it suitable for drilling ferrous and non-ferrous metals, plastics, and composite materials where a clean, accurate entry hole is critical. The straight-cylindrical shank fits standard collets and drill chucks sized to accept a 2.00 mm shank. This bit is sold individually, though the minimum order quantity is 10 units.

Key Features

• Solid carbide construction for high rigidity and wear resistance at micro diameters
• 1.69 mm (0.0665 inches) drill diameter with 120-degree standard point angle
• 38.00 mm overall length with a 12.00 mm flute length
• 2.00 mm straight-cylindrical shank for compatibility with standard collets and chucks
• Right-hand cutting direction with regular spiral flute for efficient chip evacuation
• Bright/uncoated finish — no coating buildup at the cutting edge

Compatibility

Designed as an OEM-style miniature drill bit for use in CNC machining centers, benchtop drill presses, and precision drilling fixtures that accept a 2.00 mm straight-cylindrical shank.

Installation Notes

Installation of micro drill bits should be performed by qualified machinists or toolroom technicians. Ensure the machine spindle and collet or chuck are fully powered down and locked out before changing tooling. Verify collet bore size matches the 2.00 mm shank diameter before tightening to prevent runout. At micro diameters, even minor misalignment or excessive feed rate can cause bit fracture — follow the machine manufacturer's recommended feed and speed parameters for carbide tooling at this diameter.
