Top 3 Customer Questions & Concerns ‍

1. Can these be used in a standard power drill?

   • While technically possible, these bits are extremely delicate. We recommend using them with a manual pin vise or a dedicated high-speed micro-rotary tool to prevent snapping.

2.  What materials can these bits drill through?

   • They are excellent for wood, plastics, and soft metals. They are not recommended for hardened steel or masonry.

3. Why do they come in a 20-piece pack?

   • Micro-bits are inherently prone to breaking if side pressure is applied. Bulk packaging ensures you always have a fresh replacement ready without pausing your project.
