ABSTRACT:
A floating knife of a boring tool for machining the inner surfaces of cylinders, has a cutter member and a support element arranged on both sides of the floating knife. The support elements are arranged for cooperation with the respective cutter member. The support elements are arranged behind the cutter member as viewed in the feed advance direction. The support surface of the support element is spaced behind the cutter member in the floating direction of the floating knife by a spacing corresponding to the extent of the allowable yielding of the cutter member in the radial direction, whereby the cutter member is able to machine the inner surface of a cylinder even if the latter has cross-apertures in its wall because the support member limits the radial floating of the knife to a safe extent.
