Introduction of PDC bits
1. PDC bits uses PDCs as main cutting components, with the
excellent wear-ability
and impact toughness of the PDC.
2. PDC bit 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.
3. All kinds of PDC coring and non-coring bits, and PCD Rock bits,. PDC bits can be widely used in the fields of geological exploration, coal mining, water conservancy and hydropower, construction of road and railway.
4. We also can design PDC bits according to customer requirements,
such as different geology conditions, special strata and so on.
Theory of PDC drill bits
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.
