    • Stronger connection: with friction drilling, the material is deformed without compromising its integrity. In contrast to alternative methods that involve material removal, friction drilling reduces the risk of material failure.
    • Comparable/better pull-out forces and momentum: Compared to blind rivet nuts, weld nuts, and press nuts, a Flowdrill friction drill connection has comparable or better pull-out forces and momentum.
    • What is friction drilling and how does it work?

      What is friction drilling?

      Friction drilling is a chipless drilling process in which, through the generation of frictional heat, it is possible to create a hole in a profile or material without producing chips. The specially ground geometry of the Flowdrill friction drill gradually displaces the metal, resulting in a friction-drilled hole accompanied by a distinctive collar.

      How does friction drilling work?

      Friction drilling relies on local frictional heat generated by the unique vertical movement of the friction drill to form a hole in the material. With a Flowdrill Flowtap, you can then create threads (cold forming) in the friction-drilled hole; the friction drill connection serves as a robust fastening point.

    • Which materials can be drilled?
      Basically all bendable materials such as steel, stainless steel, copper, aluminum and brass. It is also suitable for circular and square pipes, other profiles as well as sheets.
    • What is the minimum and maximum material strength?
