Machining tool, processing device and method for processing workpieces

A machining tool for processing a bore of a workpiece comprising a cutting body extending in the direction of a tool longitudinal axis and having at least one circumferentially arranged cutting element,

• characterized by
• a guide body, which adjoins the cutting body in the direction of the tool longitudinal axis, is fastened to the cutting body and has at least one circumferentially arranged guide element, wherein the guide body is free of cutting elements and wherein the guide body is configured to exert a preload force such that, during use, the at least one guide element is preloaded against a bearing for the guide body, and
• wherein the guide body comprises two guide elements which are circumferentially arranged at two angle positions, wherein an angle bisector is assigned to the two angle positions, and that the preload force extends in the direction of the angle bisector.
