Product Specification/Models
1. It has a super long life. The useful life of the PDC bit is 4~5 times than the diamond bit,

10 times than the tungsten carbide bit at least.
2. It has high drilling speed.
3. It can be operated with low pressure and low speed.
4. It has a good gage 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.

PDC bits uses PDCs as main cutting components, with the excellent wear-ability and impact toughness

of the PDC. It has a long useful life, high-efficiency, and good cost performance.

Application

PDC bit is mainly used for drilling soft and medium rock, and it must work under low drilling pressure, MID-low speed and big

drainage. It is widely used in the fields of geological exploration, coal mining, water conservancy and hydropower, construction

of road and railway.
