High quality PDC drill bit water well drilling tools
PDC(polycrystalline diamond compact) drillbit is a new product after the hot-pressed and electroplateddrill bit recent years.With special hith-frequency weldin techniques.PDC of highwear resistant si welded to the body as cutting edges.PDC bit is mainly used forgeological prospecting,coal exploration,water conservancy and powerengineering,etc.
Features
1. It has a super long life. The grinding/consumption ratio of PDCis 20-40 times that of tungsten carbide bit and 10 times that of diamondbit.
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 thestratum with formation<7
6. It has a low cost
