PDC bit crown profile, consisting of single circular arc parabola profile or dual cone profile with deeper inner taper is introduced. Cutter arrangement for various bits is determined. The bit is improved by the application of hybrid cutting structure and detailed analysis of hydraulic structure. Simultaneously, bit stability is enhanced using multiple bit stable structure design techniques such as deep inner taper, force balance and hybrid cutter arrangement etc.
