The BWI gives an indication of how fast the bit wears down, as deter-mined by an abrasion test. The higher the BWI, the faster will be the wear. In most cases, the DWI and BWI are inversely proportional to one another. However, the presence of hard min-erals may produce heavy wear on the bit, despite relatively good drillability.
