The invention relates to a disc-shaped or strip-shaped tool for machining, particularly for cutting profiles on a workpiece such as a crankshaft that is rotated during machining, comprising a number of tangentially and radially mounted indexable inserts (21). According to the invention, at least a part of the tangentially mounted indexable inserts (21) has a recess (31) that, in the tangentially mounted indexable insert (21), extends into a portion of the supporting surface (27, 28) and into a portion of the radially situated face (23, 24), and into which an upper rear section of a radially mounted indexable insert projects whose upper front section (32) radially protrudes with regard to said face (23).
