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.
Advantage of steel-body PDC bits
The strength and ductility of steel give steel-bit bodies high resistance to impact loading.
Steel bodies are considerably stronger than matrix bodies.
Because of steel material capabilities, complex bit profiles and hydraulic designs are possible and relatively easy to construct on a multi-axis, computer-numerically-controlled milling machine.
A beneficial feature of steel bits is that they can easily be rebuilt a number of times because worn or damaged cutters can be replaced rather easily.
This is a particular advantage for operators in low-cost drilling environments.
