摘要： The present invention concerns a rotary cutting tool (1) with a cylindrical supporting spindle (2) and several individual blades (3) with essentially radial cutting edges, helically ground and set at regular intervals on the outer surface of the spindle, each blade (3) having a rectilinear base (4) which inserts into a slot (5) of the same shape as said base, each individual blade (3) being mechanically fixed to the spindle (2), characterized in that it also comprises two covers (8, 9) fixed to the respective bases (8′, 9′) of the spindle (2) so as to reinforce the fixing of the blades (3).
