Abstract
A tool for use in removing plastics material from a hole comprises a work surface adapted to contact the material. A piezo-electric transducer is operatively connected through a work horn and causes the work surface to vibrate ultrasonically and thereby to heat locally the plastics material. A cavity is adapted to receive heated plastics material. The cavity has communication with a working zone adjacent the work surface. The work surface comprises an elongate boring member and rearwardly thereof a substantially annular cutting edge; the working zone communicates with the cavity via apertures disposed between the boring member and the annular cutting edge.
