Stainless Steels

Increasing process security in tough and demanding materials

Challenge Accepted – The Z70 Inox

The Challenge

Working with Stainless Steels

   


Poor thermal conductivity, therefore

  • • Overheating of the cutting edge
  • • Material-Gluing with tool (Cold welding)


  •    


    Long swarfs, therefore

    • • Tricky chip evacuation in deep blind holes
    • • Risk of swarf nest around tap shank


       

    High material toughness, therefore

    • • Difficult to machine
    • • Limited tool lifetime



    The Consequence

    Unpleasant side effects


    Cold Weldings

     
    Swarf Nests

     
    Dissatisfied Customer




    The Solution

    DC Swiss Z-Inox Thread Cutting



    Properties

    The tap is made from HSSE-PM and is available with or without internal lubrication. The flutes are helical R 45, for tapping blind holes up to 3 x D1, in Stainless and alloy steels with high elongation and tensile strength up to 1’150 N/mm2.
      


    Suitable for soluble water

    The VS surface coating provides protection against wear and cold welding. A high slip coefficient facilitates chip removal and reduces torque.


         


    Process safety up to 3 x D1
    The cutting geometry and shape of the R45 flutes generate compact, regular chips, ensuring process safety.
