3. pearl carbide specification

1).Introduction: The pearl carbide are made by 100% virgin tungsten carbide raw material. The tungsten carbide has low impurity content so the drill bits won’t crack easily. With HIP (Hot Isostatic Press) process to ensure the stable microstructure, the service life time of drill bits is longer and it can improve the working & production efficiency.

The pearl carbide are widely used for drilling the holes of pearls and they're common in the jewelry industry.
