Product Description:
PDC bit uses PDC as main cutting components, with the excellent wear-ability
and impact toughness of the PDC. It has a useful life, high-efficiency, and
good performance cost ratio.
PDC bit is mainly used for drilling soft and medium formation, it work under
low drilling pressure, midium-low speed, big drainage situation.
We also can design PDC bits according to customer requirements, such as
different geological 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 recent years. With special
hith-frequency weldin techniques. PDC of high wear resistant si welded to the
body as cutting edges. PDC bit is mainly used for geological prospecting, coal
exploration, water conservancy and power engineering, etc.
Features
1. It has a super long life. The grinding/consumption ratio of PDC is 20-40
times that of tungsten carbide bit and 10 times that of diamond bit.
2. It had 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 formation<7
6. It has a low cost
﹡We can manufacture all
kinds of bits and shells according to customer's special requirement.
Any requirement please contact us, we'll do the best service for you. Hope we
can establish a good business relationship.
