Description

OSG Micro Carbide Drill, featuring a Micro Spiral flute and an extended Reach design, is built for precision micro-drilling in tight or hard-to-reach workpieces. With a 1.55 mm diameter, it excels at creating small, accurate holes in electronics, aerospace components, and medical devices where space is limited and tolerance matters. The long-reach geometry helps you access deep cavities and recessed features without swapping to multiple tools.

Coupled with a robust SC coating, this drill delivers enhanced wear resistance and reduced friction, helping it last longer in demanding materials and environments. The micro spiral flute speeds chip evacuation, promoting smoother cuts, cleaner hole finishes, and less heat buildup during high-precision micro drilling.

  • Long-reach access for deep, hard-to-reach features: Extends your reach to deep pockets and vias, reducing the need for multiple tools and improving hole placement accuracy.
  • Efficient chip evacuation with micro spiral flutes: Promotes smooth entry and exit, minimizes clogging, and delivers cleaner, burr-free hole finishes even in challenging materials.
  • SC coated carbide for wear resistance: Keeps friction low and tool life high, delivering consistent performance in demanding applications and reducing replacement downtime.

Designed for reliable results in electronics, aerospace, and medical manufacturing, this micro drill helps you maintain tight tolerances, improve throughput, and achieve repeatable hole quality across batches. It’s a confidence-inspiring choice when precision micro-drilling matters.
