Description

OSG Micro Carbide Drill — Micro Spiral — TiAlN Coated, 0.81 mm diameter, is a precision tool designed for micro‑drilling tasks across electronics, medical devices, and other fine assemblies. It’s built for engineers, technicians, and hobbyists who need consistently accurate holes with repeatable results in small workpieces.

The micro spiral flute design promotes efficient chip evacuation and smooth cutting, while the TiAlN coating boosts wear resistance, heat resistance, and overall tool longevity. This combination enables reliable high‑speed machining even in hard or abrasive materials, helping you maintain performance without frequent tool changes.

  • Ultra-precise micro-hole accuracy: Delivers tight hole tolerances at 0.81 mm with a micro spiral flute that clears chips for smooth, burr‑minimized drilling in delicate workpieces.
  • TiAlN-coated durability: Provides exceptional wear and heat resistance, helping the edge stay sharp longer and enabling faster cutting in hard or abrasive materials.
  • Ideal for electronics and medical‑device work: Optimized for detailed, small‑diameter holes in tight tolerances, delivering reliable results in electronics, medical devices, and other fine applications.

This drill supports a efficient micro‑fabrication workflow by delivering consistent, high‑quality holes with long tool life. Its combination of precise cutting performance and durable coating helps you reduce rework, speed up production, and achieve professional results in challenging micro‑drilling tasks.
