A method of manufacturing a milling cutter having a cutting head and a coaxial integral shank comprising the steps of grinding, in a first grinding operation, a plurality of helical flutes (5) into the outer periphery of a cutter blank from a lead end (24) using a peripheral area (16) of a first grinding wheel (15) generally of frusto-conical profile and rotatable about an axis (18) generally transversely of the milling cutter axis (1), which peripheral area (16) produces, simultaneously, the following three features: a leading face (9) of a trailing tooth; a rear face (10) on an adjacent preceding tooth; and a swarf removal gullet (13) having divergent sides, grinding, in a second grinding operation, and using a peripheral edge (19) of a second grinding wheel (20), a relief face (11), which extends rearwardly from a leading end of a tooth tip, resulting in a minimum tooth wedge angle of approximately 60°, and grinding, in a third grinding operation, a radius (23) on the end of each flute. The invention also includes a milling cutter (1).
