Introduction to DTH Bit
Down - the - hole (DTH) bits are critical tools in the field of drilling. They are used in various drilling applications, such as mining, quarrying, construction, and geothermal exploration. DTH bits work by being attached to the end of a drill string and are powered by compressed air or hydraulic fluid. As the bit rotates and hammers against the rock, it breaks the rock into small fragments, which are then removed from the borehole by the circulating fluid. The design and quality of DTH bits significantly affect the drilling efficiency, penetration rate, and overall cost of the drilling project.
