Description
OSG Micro Carbide Drill - Micro Spiral - Long Reach - SC Coated is designed for precision micro-drilling in deep or hard-to-reach areas. With a 2.57 mm diameter, this specialized drill delivers accurate holes in small, delicate components, making it ideal for electronics, aerospace, and medical applications where tight tolerances matter.
The long-reach design lets you access challenging workpieces without repositioning, reducing setup time and improving hole placement. The micro spiral flute efficiently evacuates chips for smooth operation, helping maintain steady feeds and clean exits even in confined spaces.
- Long reach access: Extends drilling depth to reach deep or obstructed holes, enabling precise hole placement without moving the workpiece.
- Micro spiral for chip evacuation: Optimizes chip clearance to minimize clogging and heat, delivering smoother starts and consistent hole quality.
- SC coated carbide for durability: Hardened coating reduces friction and wear, extending tool life in demanding materials and high-production environments.
This drill supports reliable, repeatable results across electronics, aerospace, and medical manufacturing. By combining long-reach access, efficient chip evacuation, and a wear-resistant SC coating, it helps you reduce downtime, maintain tight tolerances, and achieve high-quality holes with fewer tool changes.
