2. Discriptions
PDC bits do not have the benefit of the self fluid-cleaning action between rows of teeth like roller cone bits, so they must rely on the bit's hydraulics to flush the cuttings from under the bit to prevent balling. This is accomplished with strategically positioned converging-diverging nozzles which maximize cleaning while minimizing erosion of the body near the nozzle area. Optimum hydraulic range is between 2.0 to 4.0 hydraulic horsepower per square inch. The interchangeable jet nozzles come in standard sizes from 8/32's to 14/32's.

4. Technology advantages
Custom-engineer bits for extended life, every directional PDC bit achieves directional certification through the integrated drillbit design platform, meaning dynamic stability across a wide range of directional applications. Directional PDC bits are modified for specific applications, so the possibility of unstable bit design is eliminated. Blade count, cutter layout, and hydraulic configuration are all optimized for full bottomhole coverage, higher loads per cutter, and maximum ROP.
