PDC drill bit is a new product after the hot-pressed and electroplated drill bit recent years. With special high-frequency weld in 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
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.
