Description

The OSG Micro Carbide Drill - Micro Spiral, Long Reach, SC Coated, 0.73 mm is a precision micro-drilling tool built for deep or hard-to-reach holes. It’s ideal for electronics, aerospace, and medical components where tight tolerances and clean results matter.

Its long‑reach geometry and micro spiral flute optimize chip evacuation and hole quality in challenging workpieces, while the SC coating boosts wear resistance for longer tool life in demanding machining conditions.

  • Long-reach access for tight spaces: The extended length lets you reach deep cavities and recessed features without repositioning the workpiece, delivering consistent hole placement in hard‑to‑access areas.
  • Efficient chip evacuation with micro spiral: The micro flute design rapidly removes chips, reducing heat and clogging for smoother operation and cleaner, more accurate holes in delicate materials.
  • SC-coated carbide for extended tool life: The SC coating minimizes friction and wear, providing reliable performance and longer tool life in demanding drilling jobs across electronics, aerospace, and medical components.

This drill delivers reliable, repeatable micro-holes with tight tolerances and a clean finish, helping you speed up production and reduce rework. The combination of precise 0.73 mm sizing, long reach, and durable SC coating gives you confidence to tackle challenging applications and maintain consistent results across demanding projects.
