Abstract
A tool for removing material from a surface includes a body defining a longitudinal bore and an opening connecting an outer surface of the body to the longitudinal bore. A cutting element comprising a cutting surface is dimensioned to be at least partially received by the opening. The cutting surface is configured to translate from a first position to a second position in response to a centrifugal force. In the second position the cutting surface is extended outwardly through the opening, beyond the outer surface of the body. In one example, the tool may be used to remove material, such as oxidation, from the inner walls of a cylindrical article selected from a pipe and a tube.
