OSG Micro Carbide Drill with a micro spiral flute is engineered for precise micro-drilling tasks across electronics, medical devices, and other fine applications. The 3.70 mm diameter version delivers exceptionally accurate hole sizes and reliable performance in tight workpieces.

With a micro spiral flute design, it provides efficient chip evacuation and smooth drilling, while a TiAlN coating enhances wear resistance and heat tolerance for high-speed machining in hard, abrasive materials.

  • Micro spiral flute for efficient chip evacuation: Clears chips quickly and consistently, reducing clogging and delivering clean, accurate holes in small-diameter workpieces.
  • TiAlN coating for wear and heat resistance: Enables higher cutting speeds and longer tool life in hard materials, maintaining edge sharpness and stable performance over thousands of holes.
  • Premium carbide construction for consistent results: Delivers tight tolerances and reliable hole quality with minimal deflection, even under demanding micro-drilling conditions.

By choosing this drill, you gain dependable precision, reduced downtime, and a smoother workflow. The combination of micro-spiral geometry and TiAlN coating means fewer reworks and longer intervals between tool changes, enabling you to complete delicate tasks in electronics, medical devices, or precision components with confidence. This drill is built to withstand demanding micro-drilling applications, delivering consistent hole quality and extended tool life.
