StingBlade CONICAL DIAMOND ELEMENT BIT Proving the point in hard-to-drill formations. StingBlade bits include Stinger conical diamond elements positioned across the bit face. The elements' unique 3D geometry concentrates point-loaded pressure onto the formation, fracturing high-compressive-strength rock more efficiently compared with flat-faced PDC cutters. Zhaikmunai used the StingBlade bit to drill its entire planned interval through chert-inclusive hard carbonates at 166% higher ROP, saving 6 drilling days.
