Patent ID: 7252164

Claim:
A drill bit comprising: a bit body with a bit central axis, and that defines a gage diameter; a first roller cone, attached to said bit body, rotatable around a first journal axis; a first row of cutting elements attached to said first roller cone that includes a first cutting element, said first cutting element having a first cutting tip; a first cutting tip curve defined by rotating first roller cone with attached first cutting tip around said first journal axis; a first nozzle receptacle in said bit body that defines a first projected fluid path, said first nozzle receptacle being located from 25% to 100% of the distance between said central axis and said gage diameter; said first projected fluid path being within 0.4 inches of said first cutting tip curve; a second roller cone, attached to said bit body, rotatable around a second journal axis; a second row of cutting elements attached to said second roller cone that includes a second cutting element, said second cutting element having a second cutting tip; a second cutting tip curve defined by rotating second roller cone with attached second cutting tip wound said second journal axis; a second nozzle receptacle in said bit body that defines a second projected fluid path; said second projected fluid path being within 0.4 inches of said second cutting tip curve; a first distance from said first nozzle receptacle to said bit central axis; a second distance from said second nozzle receptacle to said bit central axis; a first angle between said first journal axis and said first nozzle receptacle; a second angle between said second journal axis and said second nozzle receptacle; wherein at least one is selected from the group consisting of: said first distance differs from said second distance; and said first angle differs from said second angle.
