metal drilling bit

GREAT PDC bits combined use of High-powered PDC cutters to improve bit life.

PDC is made of diamond micro-powder and hard tungsten carbide under high temperature and high pressure.
High hardness, abrasion resistance

we have got ISO9001 certificate and our tricone bits have been sold to 30 countries all over the world.
