In a cutting tool with a head, a channel is formed through the head which receives a tool holder, the channel and holder extending perpendicular to the axis of rotation of the head. A screw in the head is provided to clamp the holder in any of a plurality of adjustment positions in the channel. A wall of the channel is recessed to accommodate part of an adjustment pin carried by the holder. The pin is internally threaded and receives a threaded spindle to form a spindle assembly which is adjustable from the outside. |
