5 blades 12 1/4 inch PDC drill bit
Polycrystalline diamond compact (PDC) bits deliver premium performance and durability for a wide range of standard drilling applications. These matrix- and steel-bodied bits incorporate the
latest cutter technology, computational fluid dynamics (CFD), enhanced hydraulics, and various structure geometries to maximize ROP.
Matrix-body bit
Matrix-body PDC bits are commonly preferred over steel-body bits for environments in which body erosion is likely to cause a bit to fail. For diamond-impregnated bits, only matrix-body construction can be used.
Steel-body bits
The strength and ductility of steel give steel-bit bodies high resistance to impact loading. Steel bodies are considerably stronger than matrix bodies.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.
