A drill bit is provided that includes a connector, which includes a shank, configured to receive torque; a proximal electrically-conductive coupler, which is disposed at a distal end of the shank, rotationally fixed with respect to the shank; and a distal electrically-conductive coupler. The distal electrically-conductive coupler is rotationally fixed with respect to the proximal electrically-conductive coupler, electrically isolated from the proximal electrically-conductive coupler, and shaped so as to define a distal-electrically-conductive external contact surface. The drill bit further includes a drill shaft including an electrically-conductive outer electrode and an electrically-conductive inner electrode. Other embodiments are also described.
