A boring tool has a cutter mounted on a holder adjustable relative to the boring tool body. Adjustment of the cutter holder is effected by displaceable wedging surfaces in engagement with each other, one of such wedging surfaces being provided on the cutter holder and the other being provided on an adjustably displaceable wedge piece, the cutter holder body being substantially cylindrical but prevented from rotating by the wedge piece having a plane surface in engagement with a plane surface of the cutter holder. |
