A milling cutter tool including a basic body and a replaceable cutting body. The cutting body includes a set of teeth which are situated with a uniform partition along one of a pair of opposite sides of the cutting body. The cutting body is fixed in a pocket having a support surface against which the underside of the cutting body is mounted. The support surface of the pocket, and the underside of the cutting body, are tipped at a negative axial angle γ of at least 0.5° in relation to a center axis (C1) of the basic body such that the teeth of the cutting body are located along a common, phantom helical line (X), which is concentric with the center axis (C1) of the basic body and has an even pitch which corresponds to the partition between the teeth.
