Walter offers milling cutter range MD133 Supreme for Dynamic Milling


Premium tool manufacturer Walter AG now offers the new MD133 Supreme milling cutter range for dynamic milling. With 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).


The tool offers key benefits for the customer in the increased process reliability, particularly during unmanned operation, and in the increased productivity with 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.


Maximum process reliability and considerably higher productivity: The new MD133 Supreme solid carbide milling cutter is not only a problem-solver for working with difficult-to-cut materials, but also for working under unstable conditions.
