ABSTRACT:
A tool for cleaning, deburring, burnishing, or otherwise treating an end of a tubular conduit comprises a rotatable body coupled to a carrier provided with an abrading substance. In one form the carrier may be accommodated within the conduit, whereas in another form the carrier is adapted to accommodate the conduit. In each case the carrier is axially slotted to enable it to expand and contract radially to cause the abrading material to engage the conduit. The body and the carrier are telescoped for relative movement and are provided with complementally tapered surfaces which react in response to relative telescopic movements to effect radial expansion and contraction of the carrier.
