Unlike the traditional center flush circulation, our Reverse Circulation PDC Bits save a lot of fuel and other operating-related costs.


Reverse circulation drilling can obtain preliminary geological data before analyzing cuttings samples and investing in detailed geological data for exploration coring plans. Reverse circulation is also faster than coring, which means drilling more holes.


We design RC PDC drill bit according to customer requirements and formation conditions. As one of the most trusted drill bit manufacturers in China, GREAT has professional staff and precise equipment to get the best drill bits for customers.


Using our drill bits can help you increase efficiency and maximize your operations, and we have comprehensive after-sales service and technical support.
