ISOprofil: freud revolutionary system that has become the window tooling standard.
For a perfect profile: the ISOprofil system automatically recovers the tool's cutting diameter after each re-sharpening.
No more machine re-programming: the wedge raises the knife until it compensates the reduction of diameter. No need for any additional measuring instruments.
A small device for a big difference: the creation of a relief angle on the support side of the Performance knife maintains its original profile constant all throughout its life.
