Roller cone drill bit having cutting elements with force axes converging at a centre

Roller cone drill bits (20) may be formed with cutting elements (60) and cutting structures having cutting element profile angles selected to minimize cone wobble and improve life of associated bearings and seals. Normal force axes of the cutting elements may intersect with each other as a force center (90) . Crest points (70) of the cutting elements may be disposed on one or more circles extending from the associated force center.
