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. Our product range covers the most diverse applications in mining, natural resources exploration, water wells, quarries and civil works.
