I had a long discussion with my German dealer yesterday regarding the VECTURO OS 400 Multi-Tool system.
I have learned that the system is IN FACT manufactured by FEIN, but it is based somewhat on the FEIN FSC 2.0, not their lower, standard units. (Those Fein FSC 2.0 units are higher end and expensive). All attachments for the Fein FSC 2.0 are compatible with the new Festool. No-Name Cheapies and other brands on the market will not fit this unit.... at least not yet.
design the Plunge unit and the other two unique attachments. They are only available on the VECTURO and will apparently not work with the Fein units.
The VECTURO has been temporarily pulled off of the German Festool site, apparently due to a delay in distribution... so you can't buy it yet, no matter where you are.
Hope this clears up some discussion in other posts regarding whether the Festool was a copy, clone, or actually manufactured by Fein.
Frank The Fein FSC 2.0 for reference.
