1. 66mm BW female thread matrix PDC drill bit
PDC drill bit is super hard m 66mm BW female thread matrix PDC drill bit aterial combined with diamond and hard alloy under high temperature and high pressure. 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. 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. Its mechanical capacity is strengthened by fully automatic vacuum heat treatment equipment. The ordinary type adopts Chinese PCD as its blade, while the super-strong type adopts American blade made by GE. Choosing proper type makes high ratio of performance and price.
Our PCD drill bits are widely used in all industries, such as coal mining, oil exploration, geological exploration, water and hydroelectric, railway and road, tunneling construction and so on. Two-wing PDC anchor bit (standard type) is applied to the hardness not bigger than f8. The working life is 10-30 times of the ordinary alloy bits, and the efficiency could be improved by 60%. Besides, the PDC bits don’t require figuring, which lows the labor intensity and helps to saves cost. GE, American company, produces the main material of the blade for two-wing PDC anchor bits (strengthened type). The diamond content is 1.5 times of the ordinary bits, which has excellent abrasive resistance and applied to medium and hard rock (f≤12). Super strengthened PDC bits adopt newly designed ball type diamond as its blade.
Features: fast drilling speed, high impact resistance. When the drill bits work, the edge is used to cut ordinary and symmetrical formation, while the ledge acts as cushioning to avoid huge drilling footage, which helps to low the possibility of damage. Thanks to that, the drilling level of complicated formation is improved.
