Brief Introduction of  High Air Pressure DTH Drill  Bits
Down-the-hole rock tools (drilling tools) are rock drilling equipment which takes compressed air as power source to partially transfer impact power into drilling holes. An air distributing device in a top hammer controls a piston to move back and forth. An impact device arranged in the front of the top hammer transfers the impact powder to a down-the-hole bit to crush rocks.
Application of High Air Pressure DTH Drill  Bits

Our DTH drill bits range covers the most diverse applications in mining, natural resources exploration, water wells, quarries and civil works.
Faetures of High Air Pressure DTH Drill Bits
