Also called pneumatic DTH hammer.Powered by compressed air medium, The continuous impact load using compressed air energy hole bottom power machine. Compressed air can double as wash hole medium at the same time. Pneumatic impact, high air pressure and low air pressure, valve or no valve type. Usually pneumatic impactor with tungsten carbide tooth bit column connection directly to impact way to breaking rock, Low-speed rotation not coring drilling in an all-round way. Mainly used in water well drilling, core drilling, geological disaster prevention engineering and mining drilling, etc. Suitable for application in the gravel and hard rock layer, special structure of the configuration bit can also be used in the soft soil layer .
