Our impregnated drill bit is manufactured from diamond and nonferrous metal powder, imported from Europe. It takes 18 hours for us to mix diamond and metal powder according to the proportion of ingredients. Diamond is uniformly distributed on the metal powder. This allows for uniform abrasion and superb cutting effect when the drill bit performs drilling. The diamond particle is securely attached to the bit, which helps to improve the drilling efficiency significantly.
The PDC drill bit matrix adopts overall sintering processing technique. This technique greatly enhances the abrasion and prevents the fall-off of the bit matrix during high speed rotation. We use the PDC with the thickness of 8mm. The PDC is resistant to impact, high temperatures and the lifespan is twice longer than ordinary PDC.
