High efficient cutter with double sided round insert MRW 1 The MRW radius cutter lowers cutting costs The new cutter lowers cutting costs and increases efficiency due to economical 8-edges per insert. Combining sharpness and cutting edge strength to this geometry makes it applicabale to a wide variety of applicaton by improving the milling performances. The double-sided inserts improve milling in a wide variety of materials. Low cutting force chipbreaker Sharp cutting edge 2 Flat lock structure Holds the insert firmly and prevents rotation of the insert during machining and provides stable machining. Wide flat binding face • Receives cutting forces evenly • Prevents insert rotation Cutting Force Wide flat contact face 3 Waved cutting edge design Maximum axial rake 12° lowers cutting forces equivalent to positive type inserts.
