The main technical parameters of impregnated core bits include diamond type, size, connection and diamond grade, matrix hardness and crown shapes etc.

While natural diamond surface set bits differ from impregnated core bits in that they only have a single layer of diamonds set onto the working surface of the bits according to a predetermined pattern. Its waterways are usually shallower than an impregnated core bits because of the single layer of diamonds.
