The elongate shaft (4) defines an elongate inner open volume through the shaft. A tip portion (18) extends from the distal end region of the elongate shaft (4). A driveshaft extends through the elongate shaft (4) from the main body (2) to the distal end region of the elongate shaft (4). A cutter head (12) is attached to the driveshaft and located in the tip portion (10), the cutter head (12) extends at least partially out of the tip portion (18). The tip portion (18) is of an electrically insulating ceramic material, and has an outer surface. An electrically conductive electrode is located on at least part of that outer surface.1/7 o -o ':1-1 0-0 U
