Abstract
A bidirectional stabilizer, which reduces impact damage while rotating into and out of a wellbore. The bidirectional stabilizer can be coupled on a first end to a drill string and on a second end to a drill bit. The bidirectional stabilizer can have an annulus configured for maximum wellbore fluid flow. A cutting portion can be formed on a shaft with a plurality of blades between the first shaft end and the second shaft end. The plurality of blades of the cutting portion can be on a first plane and a plurality of cutting nodes can be on a second plane for smoothing a wellbore. The plurality of blades can have a wrap angle for forming a particle flow path between pairs of the plurality of blades configured with a line of sight parallel to the longitudinal axis.
