Description

OSG Micro Carbide Drill - Micro Spiral - Long Reach - SC Coated, 1.56 mm diameter, is engineered for precision micro-drilling in deep or hard-to-reach work areas. The long-reach geometry lets you access internal features and through-holes without repositioning the part, while the micro spiral flute supports fast, clean chip evacuation for reliable hole quality.

Designed for electronics, aerospace, and medical manufacturing, this drill’s SC coating enhances wear resistance, helping it withstand demanding materials and high-speed machining while delivering consistent performance.

  • Long-Reach Geometry for Deep Access: Reaches into tight pockets and deep cavities, reducing setup time and the need for multiple tools so you can complete challenging holes in one pass.
  • Micro Spiral Flutes for Efficient Chip Evacuation: Optimizes chip removal in small-diameter holes, promoting smoother cutting action and reducing chip packing for cleaner, more accurate results.
  • SC Coating for Durability and Low Friction: Provides wear resistance and reduced friction, extending tool life and maintaining stability under demanding machining conditions.

With its combination of extended reach, efficient chip handling, and durable coating, this drill supports precise, repeatable micro-holes in tight spaces. It helps keep workflows moving, reduces tool changes, and delivers reliable results across electronics, aerospace, and medical applications.
