description Wellbore cleaning bits include a bit body, at least one cutting structure on the bit body, and a shank configured to attach the bit body to a drill string. Drilling systems for cleaning wellbores include a wellbore cleaning bit coupled to a drill string. The wellbore cleaning bit may include a casing bit body and a shank attached to the casing bit body and the drill string. A casing bit may be attached to a shank having a connection portion configured for attachment to a drill string to form wellbore cleaning bits for cleaning at least a section of a wellbore. Furthermore, a casing bit may be advanced into a wellbore using a drill string to clean a wellbore.
