ABSTRACT:
The boring head has a tool holder in which the cutting tool is retained by a clamping screw. The tool holder is radially adjustable by an adjustment screw having a fine thread. The adjustment screw has a flange and a pressed-on knob which bears an adjustment scale. Between the knob and the flange, the annular portion of an insert is introduced, free of axial play. The annular portion of the insert is connected to the boring head by a set screw.
The insert with the annular portion also is provided with a clamping lip which can be pressed against the tool holder by a locking screw. The tool holder with its fine adjustment can be separately mounted and constitutes an easily replaceable unit.
