Turning tool including a drive centre (6) for turning a workpiece, a first elongate member (8), a tool arm (12) angularly pivotable and slidable longitudinally with respect to the first member and a second elongate member (10) parallel to the first and capable of being abutted by the tool arm. The tool arm is thus firmly supported even though it is movable radially and longitudinally of a workpiece. The second elongate member limits movement of the tool arm towards the workpiece and can be used by the operator to guide him in providing a cyclindrical turned surface. |
