In developing the Walter Prototyp TMO solid carbide orbital thread mills for small threads from M1.6 to M8, Walter Prototyp has not only expanded its product range, but also introduced a new milling strategy. Since the cutting edge is only three thread turns in length, thread milling is performed in a special helical curve. This new operating principle leads to a significant reduction in radial forces, which in turn increases process reliability, particularly when working with materials that are difficult to cut or with very expensive components.

Thanks to the newly introduced TMO thread milling cutter with internal cooling, chip removal receives particular support for deep threads. In particular, this results in an excellent thread quality, maximum process reliability and a significantly higher tool life being achieved.

Facts and advantages:

  • Greater shank diameter for vibration-free use, even with a long clamping length
  • Short cutting edge, small helix angle and positive rake angle for reduced forces and a soft cut
  • Design for 2 x d and 3 x d deep threads with and without internal cooling

  • Our "TEC+CCS" and "GPS" expert system provides a special milling strategy tailored specifically to the respective application, optimum cutting data as well as ready-to-use program
