Product Description

8-1/2inch 6 Blades PDC Drills Oilfield Drill Bit PDC Core Bits 

Diamond PDC drills are designed to operate at high penetration rates, even in applications that require higher insert and tool counts. Its unique cutting structure layout combines the penetration potential of a traditional "single set" tool layout with the life-extending properties of a "multi-set" tool layout, adding another dimension to drill stability and smooth operation. The result is a bit that is 20% faster than conventional Pdc bits with minimal bit wear.
