The single sided Walter geometries NRR and NRF are a powerful duo for roughing applications. The NRF geometry is responsible for universal roughing in this case, while the NRR geometry is, for example, used for extremely heavy roughing of forged skins.

Walter's product portfolio in this field includes various geometries and cutting tool material grades for heavy-duty machining.

Facts and advantages:

  • high feed rates and metal removal rates in steel and cast iron machining
  • perfect chip breaking and easy chip removal
  • maximum tool life thanks to Tiger∙tec® cutting tool material grades
  • NRF geometry – two geometries in a single roughing insert – roughing and finishing of large components with a single insert
  • NRR geometry – winner for heavy roughing applications with cut depths of up to 18 mm
