78MM Water Well Drill Bits PDC Concave Three Blade Wing Drag
Brief introduction of Water Well Drill Bits
PDC concave drill bit is composed of PDC cutters and matrix body. With higher strength tungsten carbide body, the bit has better anti-erosive and toughness. The reliability and drilling efficiency is also improved by choosing premium PDC cutters.
