Description


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 powderto a down-the-hole bit to crush rocks.


The new diamond dart impactor uses the latest drilling theory to design impactor, which enables the impactor to get the best energy transfer, fast drilling speed and low air consumption. The best quality of raw materials and the most advanced processing technology, stable performance and long life. Easy to use, easy to install and disassemble, easy to repair and easy to repair.


Applications



Widely used in mines, quarries, earthworks and other engineering drilling blasting hole, guardrail hole, mountain reinforcement, anchorage and other engineering holes, geothermal exploration hole, Well bore and other fields.
