Wireline drill bits, Impregnated Diamond are used in conjunction with NQ-sized core barrels and drilling equipment to extract cylindrical rock samples (cores) from underground formations. The collected core samples are then analyzed to study the geology, mineral composition, and other characteristics of the rock layers, aiding in mineral exploration and geological research.
“N” stands for the outer diameter of the core bit, which is approximately 75.7 mm (2.98 inches).
“Q” represents the inner diameter of the core that remains after the drilling is completed, which is around 47.6 mm (1.88 inches).
