The invention refers to a tool assembly for cuttingly machining of an at least partially closed inner surface of a workpiece, e.g. a bore. It comprises an essentially rod-shaped tool support having a machining tool mounted on its end and which is adapted to be inserted into the cavity to be machined. The tool support comprises a rod member with a continuous opening extending in axial direction and with parallel supporting surfaces arranged in the region of the both ends and extending with an angle to the longitudinal axis of the rod member. A machining tool supporting member having a machining tool mounted at one end is slidably mounted at one end of the rod member and rests against the first supporting surfaces of the rod member. A control member is slidably mounted at the other end of the rod member perpendicularly to the axis of the tool support and resting on the second supporting surface, serving for the pushing-out and retiring of the tool supporting member. To this purpose a connecting member extending through the opening of the rod member is provided, being connected, with its one end, to the machining supporting member and, with its other end, to the control member, thereby coupling these elements together in a predetermined distance. |
