OD82mm 3'' DHD3.5 Dth Hammer Water Well Drilling
OD82mm DHD3.5 Down Hole Hammer For Water Well Drilling
Product introduction:
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.
