        Matrix body PDC core bit

         

        Medium to hard formation coring
        Medium short parabolic profile with medium cutter density and blade-style cutter layout helps to obtain better ROP in medium hard formations with medium compressive strength and thin hard layers.

         

        Premium cutter and duraset gage
        High performace cutters promote drilling ability in formations with intercalation. Super strong material promotes wear-resistance to prolong the service life to the bit.
