1.PDC drill bit is super hard material combined with diamond and hard alloy under high temperature and high pressure. 2.It not only has the advantages of hard and durable from diamond, but also has the advantages of high impact resistance and big blade from hard alloy. 3.It greatly improves the drilling efficiency and is the ideal drill bit for the drill operation of medium & hard as well as super hard rock. The carrier of PDC bits is forged and pressed by first-class steel. 4. Its mechanical capacity is strengthened by fully automatic vacuum heat treatment equipment.
