Natural Diamond Surface Set, set with a single layer of natural or synthetic diamond utilizing a hard matrix compound on the surface of the bit.
>>Shallower waterway.
>>Sufficient overlap to prevent premature wear of matrix.
>>Appropriate for soft, agrasive, unconsolidated rock formation,as well as, harder formation, which driller consumes faster speed
>>CROWN bit manufactures a wide range bit with different diamond grades, size, arrangement,design to maximize cutting efficiency for various rock formation.
