Description
The OSG Micro Carbide Drill with a 1.98 mm diameter is built for precision micro-drilling in deep or hard-to-reach areas. Its long-reach design and micro spiral flute ensure clean holes and reliable performance in electronics, aerospace, and medical components.
- Long-Reach access for challenging geometries: The extended flute length and slender body reach deep cavities, blind holes, and recessed features without crowding the work area, reducing tool deflection and improving hole location accuracy.
- Micro Spiral flute for efficient chip evacuation: Tight spiral channels chips away from the cutting edge, minimizes clogging, preserves cutting speed, and delivers smoother holes with less downtime.
- SC coating for extended tool life: Wear-resistant SC coating lowers friction and guards against built-up edge, helping the drill last longer in demanding materials and providing consistent performance across jobs.
This micro drill is designed to integrate seamlessly into tight-tolerance manufacturing workflows. By enabling access to difficult features, maintaining steady chip flow, and resisting wear, it helps you reduce tool changes, improve hole quality, and sustain production reliability across electronics, aerospace, and medical applications.
