Reverse Circulation DTH Drilling Tools RE542 RC Hammer Bit

Product Description

Reverse circulation hammers and bits are used in exploration and grade control applications to obtain an accurate sample with no risk of contamination. KSQ offers a range of reverse circulation hammers and drill bits that provide outstanding performance coupled with reliability and simplicity.

Reverse circulation drilling (RC) is a drilling technique that allows samples to be retrieved with minimal contamination. Drilling is typically done using a down-the-hole, tricone, or triblade bit. The samples travel through rods to a sample splitter at surface, avoiding all contact between the samples and the borehole wall. This quick execution technique is usually performed within a diameter of 150 mm and a depth that varies between 50 and 200 meters.
