The RC100 powder drilling machine is one of the advanced equipment in the field of mining exploration drilling that operates using the Reverse Circulation drilling method. In this method, sampling is carried out in the form of powder with a grain size of 0-30 mm and the rock fragments resulting from drilling are pushed out from the space between the well wall and the pipe with air or water pressure so that they do not come into contact with the well wall. This feature allows for more accurate sampling.
