The shaped output is for use with an ultrasonic tool vibratable in torsional mode. The output has a generally cylindrical first waveguide (1) with, at a distal end a second waveguide extension member (3) of reduced diameter. The second waveguide (3) is curved in one plane from the axis of the first waveguide. It has at least two blade faces (4) extending radially outwardly from its distal end. |
