Product Description

8-1/2inch 5 Blades PDC Core Bits Oilfield Drill Bit Gauge Length


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 traditional "single set" tool layouts with the life-extending properties of "multi-set" tool layouts, adding another dimension to drill stability and smooth operation. The result is 20% faster than traditional Pdc drills with minimal drill wear.
