There are many types of drill bits used in the petroleum industry and mining industry. The drill bits are classified according to different drilling methods. They can be divided into PDC drill bits, roller cone bits, scraper bits and mining diamond coring bits. These drill bits are the most basic drill bits and we all can provide.

5 7/8" mill tooth tricone drill bit is widely used in water well drilling, oil well drilling, geothermal well drilling, it can be used for drilling cement plug in very deep well.
The mill tooth tricone drill bit has longer teeth which could get much faster drilling down speed than TCI drill bits.
