Description

OSG Micro Carbide Drill - Micro Spiral - TiAlN Coated, 2.50mm is a precision micro-drilling tool designed for small, accurate holes in electronics, medical devices, and other fine assemblies. Its compact diameter and carbide construction deliver repeatable hole sizes with clean finishes in tight tolerances.

Designed for high-speed machining, the TiAlN coating boosts wear and heat resistance, while the micro spiral flute promotes fast chip evacuation for smooth, consistent drilling. This drill excels at hard and abrasive materials, providing stable hole quality from start to finish.

  • Micro spiral flute for clean, precise holes: The micro-geometry improves chip evacuation and reduces hole-wall tearing, resulting in tighter tolerances and smoother finishes.
  • TiAlN coating for wear and heat resistance: Extends tool life and maintains sharpness when drilling at high speeds in hard or abrasive materials.
  • Carbide construction for durability and reliability: A rigid carbide body maintains accuracy during high-speed micro drilling and resists wear in tough materials.

With this drill, you gain consistent hole sizes, clean finishes, and reduced rework across delicate applications like PCBs, precision instrument housings, and medical device components. The combination of a micro spiral design and TiAlN coating helps you speed setup, shorten cycle times, and achieve repeatable results across batches.
