Description

Description


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.

Choosing the right hammer is largely determined by hole size and type of rock formation. Ideally, the size of the hammer should match the required hole dimension as closely as possible, leaving just enough space for cuttings to evacuate the hole.

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.
