A constant velocity universal ball joint 11 having first and second outer ball tracks 16, 18, and first and second inner ball tracks 17, 19, forming first pairs of tracks 16, 17 which widen in a first axial direction Ri1 (α), and forming second pairs of tracks 18, 19 which widen in a second axial direction Ri2 (β). Balls 20 are guided in the pairs of tracks and have centers Z positioned on a pitch circle radius PCR around a joint centre M. A ball cage 21 holds the balls 20 in a common central plane E on to the angle-bisecting plane when the joint is articulated. There is provided an axial clearance permitting a relative axial displacement S wherein, when in the aligned condition, the ratio between the axial clearance S and the pitch circle radius PCR ranges between 0.01 and 0.09 (0.01<S / PCR<0.09).

The invention relates to a cylindrical cutter, the roller body of which comprises grooves provided along the length thereof at a distance from one another and at an angle to the longitudinal axis. Indexable inserts, particularly coated hard metal inserts, are disposed in the grooves. In order to largely prevent axial forces from acting on the milling cutter or on the material to be worked, either the grooves and thus the cutting edges of the indexable inserts are aligned sectionally at different angles, said angles being selected such that the axial forces generated in the one section during the milling process are neutralized or are reduced to a defined degree by the axial forces generated in the neighboring section, or the indexable inserts are disposed or aligned alternately in the grooves such that the axial force generated by one indexable insert during the milling process is neutralized by the axial force generated by the neighboring indexable insert.
