D Miningwell DTH hammer is a power tool at the bottom of the hole that uses compressed air as the power medium and uses the energy of the compressed air to produce continuous impact. Compressed air can also double as a washing medium. Pneumatic DTH hammer has high air pressure and low air pressure, valve type and valveless type. Usually, the pneumatic DTH hammer is directly connected with the cemented carbide stud bit to crush the rock in an impact way, and the low-speed rotation does not coring and fully drills.
