A face milling cutter head for producing trapezoidal grooves, e.g. for toothing in bevel gears having arcuate tooth flank lines, the head having a main axis and comprising a substantially disk-shaped carrier body portion with a locking ring surrounding the same; the body portion having therein at least two grooves for a corresponding number of removably inserted, substantially axially extending, rod-shaped milling cutters having respective longitudinal shaft axes, the grooves being substantially equidistant from the main axis; the cutters having chip bearing surfaces that are tilted with respect to the shaft axes, head and respective flank clearance surfaces, head and corresponding flank cutting edges, and at least three shaft surfaces; wherein cutting lines are formed on the cutters between the head and flank clearance surfaces, the cutting lines forming reference planes with the shaft axis; and wherein the spatial arrangement of the cutters, surfaces and edges is such that the reference planes run substantially parallel with at least one of the shaft surfaces and with the main head axis; the planes being constituted, on the one hand, between the cutting lines and, on the other hand, by a second line that is parallel with the main head axis and passes through the cutting lines. Additional, optional features are also disclosed.
