Optimized crown profile and cutters layout, made the bitsuitable for medium hard to hard formations with high compressive strength. Betterperformance can be achieved in deep intervals under high mud weight.
l Thermally-stable ballaset cutters
Synthetic thermally-stable ballaset cutters (TSP) aredirectly sintered into the matrix body. Premium cutters arc triangular, orspherical with the Size of I stone per carat to be selected. Compared to conventionaldrillable formation., the thermally-stable bit can bear up to 1200°. The self-sharpeningTSP can drill the medium hard to hard formations (IADC 517-737 in tri-conebill, which have high compressive strength and medium abrasiveness.
