A tool for bar peeling of solid or hollow bars includes a rotatable cutter head and a plurality of toolholders distributed around its periphery. Each toolholder is provided with a roughing insert and a finishing insert. The edge surface of each roughing insert intersect with the top surface to define three separate cutting edges whereby adjacent pair of these edges intersect at obtuse angles ranging from 120-140 degrees. The cutting edges of the roughing insert are convexly curved, whereas the cutting edges of the finishing insert are basically linear. |
