ABSTRACT:
A rotary drill bit is provided with cutting elements having a front layer of interbonded abrasive particles, such as synthetic diamonds, which layer has a thickness that varies with distance from the bit body. The characteristic relation thus obtained between bit agressiveness and bit wear can be used to monitor the bit wear condition during drilling.
