Specifications

PDC Bits:
Introduction
 
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
 
Henan zhongmei 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 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

PDC Core bit

PDC Core bit is a kind of pipe-shaped bit with PDC which can get the coring. It is used for geological exploration, coal mining, water canservancy and hydropower, road construction, railway, bridge and building.

PDC Anchor bit

Application: Apply to the anchor-network support hole drilling in coal mine, transportation, hydropower, and so on.

Characteristics: high wear resistance and impact-resistant toughness; long drilling life,, drilling efficiency can be promoted sharply in penetration of soft and medium soft formation; laber intensity can be reduced.
