It works on the Fein Supercut which is the higher end multi tool. The machine is essentially what Festool modeled the Vecturo on as Fein is the original. The Supercut is their best tool and to be honest, if I get a corded version, unless I come across some crazy deal, the Supercut multi master will end up being the one I get, but the 350 was the one I originally wanted. The only reason I want the Vecturo is because of the plunge base. But, there is a slight modification that has to be done to accommodate the base. Super easy and I think last year one of our members even posted how to do it. Also there are several mentions of this mod on other sites. Long story short, it works but only with the slight mod and only on the Supercut.
