Description
OSG Micro Carbide Drill - Micro Spiral - Long Reach - SC Coated is a precision micro-drilling tool designed for deep or hard-to-reach holes. Its long-reach geometry enables access to tight workpieces, while the micro spiral flute provides efficient chip evacuation for smooth, consistent performance. The SC coating enhances wear resistance, reducing friction and extending tool life in demanding materials and processes. Ideal for electronics, aerospace, and medical applications where precision matters.
- Long Reach Design: Access deep or hard-to-reach features without repositioning the workpiece, enabling accurate holes in tight assemblies.
- Micro Spiral Chip Evacuation: Efficient chip removal reduces clogging and heat, producing cleaner holes and steadier cuts in delicate materials.
- SC Coated Carbide: Wear-resistant coating minimizes friction, extending tool life and maintaining sharpness through demanding machining conditions.
This drill delivers reliable, repeatable results across precision-focused industries. By combining a compact 1.81 mm diameter with a long-reaching tip and resilient coating, it supports tight tolerances, reduces downtime from tool changes, and helps you complete microholes in electronics, aerospace, and medical components with confidence.
