Introduction
PDC bits uses PDC 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.
PDC bit is mainly used for drilling soft and big drainage.
Renqiu Dream Bits can supply all kinds of PDC coring and non-coring bits, PDC sintering matrix bits and PDC anchoring bit. PDC bit can be widely used in the fields of geological exploration coal mining, water conservancy and hydropower, construction of road and railway.
We also can design PDC bits according to customer requirements, such as different geology condition, special strata and so on.
Theory
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 techniques, PDC of high wear resistant is welded to the body as cutting edges. PDC bit is mainly used for geological prospecting coal exploration, water conservancy and power engineering, etc.
Features
- 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.
- It has high drilling speed.
- It can be operated with low pressure and low speed.
- It has a good gage protection.
- It can be used widely, more suitable for drilling in the stratum with hardness coefficient f<9
- It has a low cost
