Description

The PDC bits fail 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.
 
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
