Abstract: Method and apparatus for adjusting the position of a cutting tool. In one embodiment, a boring tool includes a coupling member which is driven by a CNC boring machine, and a sliding tool holder which is slidably coupled to the coupling member. A frictional force resists sliding movement of the cutting tool holder. The frictional force is sufficient to retain the position of the cutting tool during machining operations.

In another embodiment, either a surface of the sliding tool holder or a surface of a frictional member are contoured with a shape that corresponds to a desired contour of a sidewall of a hole. During machining, a follower in contact with the contoured surface causes the cutting tool holder to slide laterally during machining, thus contouring the sidewall of the hole.
