Description
The OSG Micro Carbide Drill - Micro Spiral - Long Reach - SC Coated, 1.46 mm, is a precision micro-drill designed for deep or hard-to-reach holes. Built for electronics, aerospace, and medical applications, it delivers accurate, clean holes in small-diameter workpieces.
Its long-reach body lets you reach deep cavities without repositioning the part, while the micro spiral flute provides efficient chip evacuation for smooth, steady cutting. The SC coating adds wear resistance to extend tool life and reduce friction in demanding environments.
- Long-Reach Precision Access: Drills deep or recessed holes without repositioning the workpiece, saving setup time and improving accuracy on delicate micro-features.
- Micro Spiral Flute for Efficient Chip Evacuation: Tiny, efficient flutes clear chips quickly, minimizing heat buildup and delivering consistent hole quality in micro-scale work.
- SC Coating for Wear Resistance: The coating reduces friction and wear, helping the tool last longer in challenging materials and maintain sharpness for reliable performance.
With its small 1.46 mm diameter, long reach, and wear‑resistant SC coating, this drill enables precise, repeatable micro-drilling that supports faster cycles, fewer tool changes, and higher-quality holes in electronics, aerospace, and medical parts.
