Description

OSG Micro Carbide Drill - Micro Spiral - TiAlN Coated is a precision micro-drill designed for high-accuracy hole making at small diameters. With a 4.00 mm diameter, it’s ideal for electronics, medical devices, and other fine applications where clean, precise holes matter. The TiAlN coating enhances wear and heat resistance, helping you cut faster while preserving the edge for longer tool life.

The micro spiral flute geometry optimizes chip evacuation, reducing clogging and heat buildup for smoother drilling and tighter hole tolerances. The coating and carbide construction work together to deliver reliable performance in hard or abrasive materials, delivering consistent results across jobs with minimal downtime.

  • Micro spiral flute design: Improves chip evacuation for smoother drilling and tighter, more consistent hole tolerances in delicate materials.
  • TiAlN coating for wear and heat resistance: Extends tool life and maintains sharpness when cutting hard or abrasive materials at higher speeds.
  • Rigid carbide construction: Delivers stable drilling with minimal deflection and burr-free results, even on demanding micro-scale tasks.

This drill supports efficient workflows by delivering repeatable, high-quality holes, reducing tool changes, and enabling faster production for precision assemblies. Its combination of micro-geometry, durable coating, and solid carbide fidelity makes it a dependable choice for professionals and hobbyists who require consistent, professional-grade results in tight tolerances.
