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.
• Our products go from 3 to 25 inches drilling diameter.
A. Deliver maximum energy to drilling bit, fast drilling speed and
low air consumption due to the special inner structure of HD series
DTH hammer designed according to newest rock drilling theory.
B. Smooth performance and long service lifeof HD series DTH hammer
due to high quality alloy steel materials and advanced processing
technology adapted.
C. Low problem rate and easy to maintenancedue to simple, reliable
and easy assemble and disassemble inner structure of hammer.
d. Easy to depart bit from hammer due to multi- Head thread
connecting chuck and cylinder of hammer.
e. Interchangeable with DTH bit and drill pipe.
