Professional diamond TAW TBW TNW geological exploration core drill bits
Features
1. They have super long life. The grinding/consumption ratio of PDC is 20-40
time higher than that of alloy bit and 10 times higher than that of diamond bit.
2. They have high drilling speed.
3. They can be operated with low pressure and low speed.
4. They have good gage protection.
5. They can be used widely, more suitable for drilling in the stratum with
hardness coefficient f<9.
6.They have competitive cost.
Theory
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.
