Description

The OSG Micro Carbide Drill with a 0.25 mm diameter is engineered for micro-drilling tasks where precision matters most. Its micro spiral flute and carbide construction deliver highly accurate, burr-free holes in electronics, medical devices, and other detail-heavy assemblies.

Coated with TiAlN, this drill maintains cutting performance at higher speeds and through hard, abrasive materials. The protective coating boosts wear and heat resistance, helping you achieve consistent results and longer tool life in demanding manufacturing environments.

  • Micro Spiral Flute Design: Optimizes chip evacuation for clean, precise holes and reduced clogging in micro-scale work.
  • TiAlN Coating for Wear and Heat Resistance: Extends tool life and enables higher-speed cutting on hard, abrasive materials without dulling.
  • Ultra-Fine 0.25 mm Diameter: Enables accurate, repeatable holes in electronics, medical devices, and other detail-oriented applications with tight tolerances.

This combination of precision geometry and protective coating helps you streamline micro-drilling workflows: fewer tool changes, less rework, and more consistent hole quality across delicate substrates. You’ll improve throughput in electronics and medical device manufacturing while maintaining exacting tolerances that meet exact specs and assembly requirements.
