The Advantage of RC PDC Bit

The raw material of GREAT's RC diamond PDC bit is heat-treated steel and has a strict inspection tracking report.

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 bit according to customer requirements and formation conditions, and we have professional staff and precise equipment to get the best products for customers.
