A sophisticated milling specialist: The MD133 Supreme

With the new MD133 Supreme, premium tool manufacturer Walter is launching its first ever range of milling cutters specially developed for the requirements of dynamic milling. Thanks to diameters of 6 to12 mm (where z = 5) or 16 to20 mm (where z = 6) and cutting lengths (Lc) of 3 × Dc, with necks up to 4 × Dc and 5 × Dc, the milling cutter is perfectly 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 lengths. The milling cutter's range of applications is differentiated by two different grades: WJ30RD for steel (secondary application: Cast iron) and WJ30RA for stainless steels (secondary application: ISO S, N). This new milling cutter stands out as a solution for working with difficult-to-cut materials or under unstable conditions (machine, workpiece, clamping).

Walter sees the key benefits for the customer in the increased process reliability, particularly during unmanned operation, and in the increased productivity thanks to a higher metal removal rate combined with a reduction in machining time. By making full use of the entire cutting length in the dynamic milling strategy, the tool has even wear behaviour. In addition, heat is correctly dissipated via the chip as far as possible, which leads to an improved tool edge life. Its special features make the MD133 Supreme of interest not only for mass producers, but also for users with smaller quantities and a diverse range of tasks. Typical areas of application for the new milling cutter line: General mechanical engineering, aerospace, energy, and mould and die making industries.
