Product Description

Product Introduction:
Reverse circulation hammers and bits are used in exploration and grade control applications to obtain an accurate sample with no risk of contamination. Sollroc offers a range of reverse circulation hammers and drill bits that provide outstanding performance coupled with reliability and simplicity.
Reverse Circulation, or RC Drilling, is a clean and environmentally friendly method of deep foundation installation. It employs dual-wall drill rods, comprised of an outer drill rod with an inner tube . As the sections of drill rod are screwed together, the inner tubes overlap and seal with O rings. This provides a continuous path for the drill tailings to be transported from the bit face to the surface.

Product Advantages:
1.Although the process can be costly the overall drilling costs can actually be reduced by up to 40% when using reverse circulation drilling.
2.Results from reverse circulation drilling can be revealed much faster as the completion of the drilling process is done quickly.
3.The method is safe to use and requires fewer man hours.
4.Reverse circulation drilling requires less water than other mining methods.
5.Reliable and stable performance
