Too small specific pressure (40-60N/grain for surface-mounted drill bits and 300-500N/cm2 for impregnated drill bits) is also not allowed, because it may cause diamond polishing in the complete weakly abrasive rock. And make the diamond unable to cut into the rock. The hardness, abrasiveness and fissure of the rock must be considered when selecting the drill speed. It can also be judged whether the use of diamond bit is reasonable by analyzing 

the change of the ROP. The rate of change of the ROP of various types of drill bits is different. Under the condition of correct selection of the parameter combination, the ROP of impregnated bits should not change much.

The initial mechanical drilling speed of the table-set drill bit increases and will start to decrease after reaching a 

certain maximum value. However, it is very difficult to determine the exact time point of tripping and replacing the drill bit according to the existing criteria. It is usually combined with the change characteristics of the mechanical drilling speed and experience to judge the wear of the drill bit.
