Description:
This kind of PDC bits (polycrystalline diamond composite bits) 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 to handle a wide range of complex-shaped formations (strata). Its main components are steel body and polycrystalline diamond composite sheet.
The PDC bits fall into two types: steel-body type and matrix type. The steelbody 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.
The bits can be divided into coring type and non-coring type. This kind of bits not only has the same hardness and wear-resistance as the diamond, but also has tungsten carbide supporter to strengthen its abrasion resistance and impact resistance.
As for its packing, the PDC bits are first packaged by cartons, and then the carton-packaged bits will be packed again by standard plywood boxes.
