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.
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.
Hunan Feiray can supply all kinds of PDC coring and non-coring bits, PDC sintering matrix bits and PDC anchoring bits. 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 conditions, special strata and so on.

Sharp-edge PDC drill bit use the special-shaped PDCs as cutting components, the sharp-edge PDC has the excellent wear-ability and impact toughness as the normal PDC. At the same time, with the special shape design of the diamond layer, it can avoid the PDC force too centralized, so that reducing the PDC damage and extending the useful life of the bit.
This kind of PDC bit has a long time useful life, high-efficiency, and good cost performance, mainly used for drilling soft and medium rock, and can widely used in the fields of geological exploration, coal mining, water conservancy and hydropower.

We can design the Q, W series sharp-edge PDC drill bits as your different geological conditions and hardness of rocks.
