The single-sided Walter Valenite 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-duty roughing of forged skins.

Walter Valenite's product portfolio in this field includes various geometries and cutting tool materials 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 materials
  • NRF geometry – two geometries in a single roughing insert – roughing and finishing of large components with a single insert
  • NRR geometry – winner in heavy-duty roughing applications with cut depths of up to 18 mm
