OK, so I am starting a topic with no content 

       Hoping that this can become a reference (sticky) as to which blades fit which oscillating multitools. And maybe a good explanation of the various types of mountings.  Which types are compatible, cross compatible, backwards compatible , etc. There have been a number of topics  and questions on this over recent years and I still can't easily sort it out since it is spread through out the forum and there is also incomplete or over ridden terminology involved.

     I would like to keep it to  just the blades for ease of reference. Blade adapters OK, but not other accessories.

    Those who know.........................  please contribute to this topic. I think it will help a lot of people.

The Fein 63733005010 adaptor and clamping bolt will allow you to fit Fein Multimaster accessories on to the Festool Vecturo OS 400 which uses the Fein Supercut 2.0 mounting. I bought this adapter and it works fine with Multimaster accessories. But it seems that there is a problem when using the Festool plunge base: the adapter protrudes a half-inch which means that there's a gap between the Multimaster blades and the magnet.

The Fein 35222952050 adapter is required to fit Starlock blades on Supercuts tools with a quick in lock such as the Festool Vecturo OS 400. I haven't used it yet, but it seems that this adapter will accept Starlock, Starlock Plus and Starlock Max accessories.

According to the Festool live video on the OSC 18, only the long blades work with the magnet and turn speed down to 4.
Question - is there an adaptor to allow other blades to fit the OSC supermax fitting?

I sold my 15 year old Fein to my brother in law, and bought a corded Vecturo about a year after they came out (so I could get and use the accessories like the plunge base). I also bought ALL the adapters so I could use the myriad collection of blades I had accumulated.

Problem is now ANY time I want to use the saw I grab the blade I want for the application and then spend ten minutes fussing with WHICH adapter, WHICH bolt, and WHICH orientation of the adapter to use to mount the blade I want.

AND - about a year later the Fein died, brother in law took it to the local nail gun repair shop, they sent it to Fein - who LOST it, and sent him the newest most powerful model as a replacement.......

Last - Every time I need it now it seems that it's out somewhere about a hundred feet from electricity......... This IS a tool that deserves to be cordless.

If your question is can you put the long blades on non-starlockmax, then no not that I could find. I picked up a Fein Multimaster last year with the intention of using it with the plunge base. Unfortunately, I didn't do enough research and I can't use long blades with Starlock Plus.

Ahhh, but you can use long blades with Starlock Plus tools:
