The OSG Micro Carbide Drill, 1.55 mm diameter, is a precision micro-drill designed for ultra-small holes in electronics, medical devices, and other detailed assemblies. Built for reliability and accuracy, it delivers consistent results where every hole counts.

Equipped with a micro spiral flute and a TiAlN coating, this drill maintains sharpness under demanding cuts and excels in high-speed machining of hard or abrasive materials, helping you reduce tool changes and improve throughput.

  • Micro Spiral Flute Design: Optimizes chip evacuation and minimizes clogging, delivering clean, precise holes in micro-diameter tasks such as 1.55 mm.
  • TiAlN Coating for Wear and Heat Resistance: Significantly extends tool life by resisting wear and heat buildup during high-speed cutting in hard, abrasive materials.
  • Precision for Fine Applications: Delivers repeatable hole quality for electronics, medical devices, and other meticulous assemblies, reducing rework and downtime.

With this drill, you can achieve precise, burr-free holes consistently, improving yield and reducing deburring time. The micro spiral design keeps chips moving away from the cutting edge, maintaining smooth cuts in micro-scale diameters, while the TiAlN coating supports higher speeds and longer tool life—making it a dependable choice for production or prototyping across electronics, medical devices, and other fine applications.
