Description | |
Material | 95%, 99%Alumina, or Zirconia |
Features | It is a simple structure and reasonable design. It makes materials cost down and ensuring the reliability and stability of the guide wire. The outer surface of the guide wire groove has been polished, which greatly reduces friction, effectively decreases wear and tear, and improves work efficiency. |
