RECOMMENDED DRILLING PARAMETERS FOR APPLICATION

The cutting structure of the bits varies according to the rock formation. Soft bits will have longer protruding teeth or chisel-shaped buttons, and fewer, more widely arranged teeth. Medium formation bits will have much closer teeth than soft formation bits, and the protrusion of the teeth is reduced. The teeth are very short and closely arranged on hard formation bits. Because of the shorter teeth the penetration of the rock bit during drilling is less than with soft or medium formation bits, but the other bits cannot be used in hard strata.
