ABSTRACT:
A saw tool, especially a circular saw blade, an endless saw blade, a mill saw blade or the like, with a blade-shaped tool body having detachably connected thereto at least one cutting member with a clamping element between two tensioning surfaces of the tool body. The saw tool is characterized primarily in that for purposes of obtaining the full tensioning and engaging effect of the cutting member and clamping element during a change in position of the clamping and engaging surfaces caused by the clamping deformation, the clamping element includes floating bearing means. The clamping element is an eccentric peripherally having a smaller radius of curvature than corresponding inner surfacing of a recess of an intermediate piece therewith. The intermediate piece for pivotal support at the eccentric is located with play in the recess of the tool body.
