PDC Bit (Polycrystalline Diamond Composite Bits)

This kind of PDC bit is specially used in drilling a variety of strata (formations) under 6th grade, due to its good impact resistance, high efficiency and long lifespan, the PDC bits can be used in handle a wide range of complex-shaped formations

The PDC bit fall into two types: Steel-body type and matrix type, the steel-body type means that the polycrystalline diamond composite sheet is welded onto the steel body by the silver soldering process, and it is quite applicable to drill bits with simple structures. The matrix type is the type that the polycrystalline diamond composite sheet is welded onto the powder matrix, and it is very suitable for drill bits with complex structure
