Patent ID: 7607496

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, wherein said driver contains an outer radial surface that is disposed within said sleeve, and wherein said outer radial surface contains an outer coating material for preventing wear with said sleeve during rotation; a first bit having a first end, and 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 of openings therein for placement of a plurality of pinions, said pinions having a pin disposed there through, and wherein said sleeve has a radial shoulder for attaching said plurality of pins; a housing having a first end, and wherein said first end has a second bit formed thereon, and 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.
