Description
The OSG Micro Carbide Drill with Micro Spiral flute, Long Reach design, and SC coating is built for precision micro-drilling in tight or deep work areas. Ideal for electronics, aerospace, and medical applications, this 1.15 mm drill reaches difficult pockets and recesses without repositioning the workpiece, helping you achieve accurate holes where space is limited.
The micro spiral flute promotes efficient chip evacuation and smooth cutting, reducing heat and chatter for consistent hole quality. The SC coating enhances wear resistance, lowering friction and extending tool life in demanding machining conditions so you can rely on repeatable results over multiple jobs.
- Long Reach access: Optimized for deep or hard-to-reach holes, reducing setup time and maintaining accurate hole location in challenging workpieces.
- Micro spiral with efficient chip evacuation: Helps prevent clogging and heat buildup, delivering clean holes and smoother operation in delicate materials.
- SC coating for durability: Provides superior wear resistance and lower friction, extending tool life in tough machining environments.
This drill supports faster workflows, fewer tool changes, and more consistent results across precision-focused projects. By combining a tiny, stable cutting edge with extended reach and a robust coating, it helps you achieve reliable, high-quality holes in electronics, aerospace components, and medical devices, time after time.
