A drill bit is a device attached to the end of the drill string that breaks apart, cuts or crushes the rock formations when drilling a wellbore, such as those drilled to extract water, gas, or oil.
The drill bit is hollow and has jets to allow for the expulsion of the drilling fluid, or mud, at high velocity and high pressure to help clean the bit and, for softer formations, help to break apart the rock.
Tricone drill bits: A tricone bit comprises three conical rollers with teeth made of a hard material, such as tungsten carbide. The teeth break rock by crushing as the rollers move around the bottom of the borehole.
PDC drill bits: A PDC bit has no moving parts and works by scraping the rock surface with disk-shaped teeth made of a slug of synthetic diamond attached to a tungsten carbide cylinder
PDC drag bit: A drag bit is a comprehensive drilling bit, mainly used for water wells, mining, geothermal, environmental and exploration drilling. It is suitable for drilling in soft and soft-medium formations with fast penetration rate and high efficiency, and special for the large diameter holes’ drilling.
