Type of the bit matrix
The matrix of our impregnated bits is designed to expose new diamonds to the bits' cutting face as wear occurs. Fast penetration rate is maintained as a result of this action, also with long life using time is important, meanwhile it will keep the cost of diamond drilling to a minimum.
The optimum diamond size, concentration and matrix type are dependent on the hardness and abrasiveness of the formation to be drilled.
