Abstract: 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.

The tubular body may comprise a fluid passageway extending therethrough, and the valve piston may be disposed within the tubular body, the valve piston configured to move axially downward within the tubular body responsive to a pressure of drilling fluid passing through a drilling fluid flow path and configured to selectively control a flow of fluid into an annular chamber. The push sleeve may be disposed within the tubular body and coupled to at least one expandable feature, the push sleeve configured to move axially responsive to the flow of fluid into the annular chamber extending the at least one expandable feature. Additionally, the expandable apparatus may be configured to generate a signal indicating the extension of the at least one expandable feature.
