What Are Tungsten Carbide Micro Drills?

Tungsten carbide micro drills are ultra-small precision drilling tools made from solid carbide materials. They are designed for drilling tiny holes with high accuracy, excellent wear resistance, and long tool life.

Micro drills usually range from:

• 0.05 mm to 3.0 mm diameter

• Common sizes: 0.1 mm, 0.2 mm, 0.3 mm, 0.5 mm, 0.8 mm

Because of their extreme hardness and rigidity, carbide micro drills are widely used in high-precision industries.
