Description

OSG Micro Carbide Drill, 4.15 mm diameter, combines a Micro Spiral flute with a TiAlN coating to excel in micro-drilling tasks where precision matters. It's designed for professionals and serious hobbyists who need tiny, consistently located holes in electronics, medical devices, and other fine components. The micro-spiral geometry promotes smooth cutting and reliable chip evacuation, helping you achieve clean hole edges and tight tolerances from the first cut.

With the TiAlN coating, these drills deliver superior wear and heat resistance, enabling higher-speed machining and longer tool life even in hard or abrasive materials. This combination supports demanding production environments while maintaining reliable performance and reducing the need for frequent tool changes.

  • Micro Spiral Flute Design for Efficient Chip Evacuation: Keeps chips away from the cutting edge, reducing clogging and heat buildup to deliver smooth, consistent drilling at micro diameters.
  • TiAlN Coating for Wear and Heat Resistance: Extends tool life and maintains sharpness during high-speed drilling in hard or abrasive materials, reducing downtime and replacement costs.
  • Precision Micro Carbide Construction for Detail Work: Delivers stable, accurate hole sizes at fine tolerances, ideal for electronics assemblies, medical devices, and other precision-focused applications.

This drill is built to help you finish micro-drilling tasks with confidence—delivering precise holes, dependable performance, and longer tool life across delicate and demanding projects. Whether you’re assembling tight-tolerance components or fabricating fine parts, it supports consistent results and efficient workflow.
