Abstract
A downhole tool has a main body that is cylindrical and includes a top coupling that couples to a drill string. A second body that is cylindrical is positioned at least partially within the main body. The second body has a bottom coupling that couples to a drill bit. Springs are positioned within the downhole tool and transmit an axial force to the drill bit. A first set of grooves is formed on an interior of the main body, and a second set of grooves is formed on an exterior of the second body. Balls travel within the first and second sets of grooves. At least some of the balls simultaneously engage the main body and the second body.
