        Thermal stable polycrystalline bit

         

        Medium hard to hard formation drilling
        Optimized crown profile and cutters layout made the bit suitable for medium hard to hard formations with high compressive strength. Better performance can be achicvend in deep intervals under high mud weight.

         

        Thermally-stable ballaset cutters
        Synthetic thermally-stable ballaset cutters(TSP) are directly sintered into the martrix body. Premium cutters are triangular or spherical with the size of 1 stone per carat to be selected. Compared to conventional drillable formation, the thermally-stable bit can bear up to 1200
        . The self-sharpening TSP can drill the medium hard to hard formations(IADC 517-737 in tricone bit), which have high compressive strength and medium abrasiveness.
