Low pressure DTH hammer is a mechanical tool for drilling operations, mainly in mining, geological exploration, water well drilling and construction engineering. Compared with high pressure DTH hammers, it normally operate at lower air pressures, usually in the range of 7-15 bar (100-220 psi). Its design and operation enable it to drill efficiently in medium-soft to medium-hard geological conditions. #dthbits #cir90drillbit #lowpressurebits #hammerbits
