Products Description
PDC concave drill bits are made of high-quality diamond composite sheets and high-density diamond composite sheets. It can save
drilling cost greatly and has a higher rotary.We can customize any size including non-standard size. And customerscan choose build
high performance wear-resistant materials on the surface of blade or not. It is a first choice for soft formationdrilling.
