PDC (Polycrystalline Diamond compact)drill bit is a new product after the hot-pressed and electroplated  drill bit in recent years. With special high-frequency welding tenhniques.PDC of high wear resistant is welded to the body as cutting edges.PDC bit is mainly used for geological prospecting,coal ecploration,water conservancy and power engineering,etc.

 

1.It has a super long life.The grinding/consumption ratio of PDC is 20-40 times higher than that of alloy bit and 10 times higher than that of diamond bit

2.It has high drilling speed.

3.It can be operated with low pressure and low speed.

4.It has a good gauge protection.

5.It can be used widely,more suitable for drilling in the stratum with hardness coefficient f<9.

6.It has a low cost.
