DTH drill pipes Down-the-hole drilling tools are used for down-the-hole drilling vehicles or down-the-hole drilling rigs. They are large-diameter drilling tools that are widely used in open-pit mines, building stone mining, hydropower construction projects, cement industry mines, and some large underground metal mines. Down-the-hole drilling tools are rock drilling machines that use compressed air as power. According to the different gas pressures, they can be divided into two types: low air pressure (0.6-1.0Mpa) and medium-high air pressure (1.0-2.5Mpa). Different types of drilling rigs require corresponding down-the-hole drilling tools....
