Walter USA, LLC says its new MD133 Supreme milling cutter is designed specifically for dynamic milling and delivers increased process reliability, particularly during unmanned operation. The milling cutter offers increased productivity because it is capable of a high rates of metal removal and it reduces machining time. The MD133 Supreme has diameters of ½ –¾" (6–20 mm) and cutting lengths to 5 × Dc. They are designed for operating parameters typical of dynamic milling, such as a small width of engagement and a high depth of cut facilitated by a large cutting length. A chip breaker guarantees short chips even when working with large cutting depths. This milling cutter is available in two grades: WJ30RD for steel (secondary application: cast iron) and WJ30RA for stainless steels (secondary application: ISO S, N).

The milling cutter uses of the entire cutting length, giving it an even wear pattern. Additionally, heat is dissipated via the chip, which leads to an improved tool edge life. The MD133 Supreme works for high volume production environments and for users with smaller batch sizes. The MD133 Supreme has typical application areas in general engineering, aerospace, energy, and the mold and die industries.
