Development status of PDC bit

- Jan 03, 2019-

In recent years, the quality and type of PDC cutting teeth have changed dramatically. If the teeth of the 1980s were compared with those of today's teeth, the difference would be considerable.

Due to the change of mixing process and manufacturing process, the quality performance of today's cutting teeth is much better, which makes the anti-erosion and impact resistance of the drill bit greatly improved. Engineers have also optimized the interface between tungsten carbide substrates and synthetic diamonds to improve the toughness of cutting teeth. Innovations in layered diamond processes have also been used to improve the abrasion resistance and thermal stability of products.
