ABSTRACT:
A milling head having a shaft for attachment to a machine tool, and at least one cutting insert or bit, characterized in that the cutting insert is supported in a tiltable or swivelable holder having a swivel axis extending perpendicularly to the axis of rotation of the milling head. Stopping means is situated between the milling head and the holder, against which the holder rests in its working position. A cam plate is held in a stationary position such that the cam plate cooperates with the holder to tilt or swivel the latter along a portion of its arcuate movement thereby lifting the cutting insert off the surface to be machined. The stopping means may include travel limit elements that comprise a bore in the holder and a protruding pin which engages with the bore. Biasing means is provided in the form of a spring arranged so that it tends to bias the holder into its working position.
