PDC Hard Rock Drilling Drill Bit for Oil Well Drilling
PDC drill bits
Polycrystalline diamond materials, for use in polycrystalline diamond compact (PDC) bits, are one of the most important material advances for oil drilling tools in recent years.
Fixed-head bits rotate as one piece and contain no separately moving parts.
When fixed-head bits use PDC cutters, they are commonly called PDC bits.
Since their first production in 1976, the popularity of bits using PDC cutters has grown steadily, and they are nearly as common as roller-cone bits in many drilling applications.
Steel-body
Steel is metallurgically opposite of matrix.
It is capable of withstanding high impact loads, but is relatively soft and, without protective features, would quickly fail by abrasion and erosion.
Quality steels are essentially homogeneous with structural limits that rarely surprise their users.
Steel body bits are manufactured by machining the steel bars per design.
