Description

OSG Micro Carbide Drill — Micro Spiral — Long Reach — SC Coated, 0.55 mm diameter, is built for precision micro-drilling in tight or hard-to-reach areas. The long-reach design lets you access deep features and complex geometries without repositioning the workpiece.

The micro spiral flute ensures efficient chip evacuation for smooth, clean holes, while the SC coating provides wear resistance and reduced friction. This makes it a reliable choice for high-precision work in electronics, aerospace, and medical manufacturing where consistent results matter.

  • Long-Reach Design: Reaches deep features and recessed work areas with consistent hole location, minimizing the need for multiple tools or setups.
  • Micro Spiral Flute for Chip Evacuation: Efficiently clears chips to prevent clogging, supporting smoother operation and better hole quality in delicate materials.
  • SC Coating for Durability: Reduces friction and wear, extending tool life and helping maintain sharpness through demanding drilling tasks.

With its tiny 0.55 mm diameter and robust carbide construction, this drill delivers reliable, clean holes across thin sheets and dense substrates alike. It helps streamline production by reducing tool changes, improving hole quality, and delivering dependable results in tight tolerances. Whether you're prototyping electronics, manufacturing aerospace components, or fabricating medical devices, this drill supports precise, repeatable performance you can trust.
