Patent ID: 8016051

Claim:
An apparatus for drilling a well bore with a down hole motor, with the down hole motor having a power shaft for imparting rotational movement, the apparatus comprising: a driver operatively connected to the power shaft, said driver having a cylindrical body, wherein an outer portion of said cylindrical body contains a plurality of cogs; a first bit having a first end, wherein said first end is connected to said driver so that rotational movement of said driver is imparted to the first bit; a sleeve disposed about a portion of said power shaft, said sleeve having a plurality pinions placed therein; and a housing having a first end, wherein said first end has a second bit formed thereon, wherein the first bit is offset relative to the second bit so that the first bit extends farther into the well bore relative to the second bit, wherein said housing has an internal portion that contains internal cogs, and wherein said internal cogs engage said pinions so that as said driver rotates in a first direction, rotation is imparted to said pinions which in turn imparts a counter rotation to said second bit.
