Thanks to its tough substrate and optimised geometry, the Protostar® Qmax ensures maximum metal removal rates, even when machining demanding materials. The tools are available with two different knurled profiles, the HR and the HNR profile. Due to its positive geometry, the HR profile is generally used more when machining in unstable conditions. The HNR profile is extremely solid and should therefore predominantly be used in stable conditions.

Facts and advantages:

  • maximum metal removal rate
  • internal cooling aids chip removal and increases process reliability
  • very good roughed surface due to improved roughing profile
  • all tools have the latest TiAlN coating, offering advantages for both dry and wet machining
