Product Description

PDC Introduction:
PDC (Polycrystalline Diamond Compact) is composed of diamond micron powder and cemented carbide 
liner that are sintered together under high temperature and high pressure. It not only has the high wear 
resistance that diamond has, but also has the high impact-resistance toughness.


Using PDC as the main cutting components;
With the excellent wear ability and impact toughness of the PDC;
High drilling speed;
Improving the drilling efficiency and reduced labor intensity;
It has high efficiency and strong wear resistance for drilling. 

PDC bits are most used in soft and m
