What part is this?

[maxtool]

I found these two parts under my CMS - can you help me figure out what they are?

You could try to take a look at the ekat catalog and see if anything rings a bell.

Wonder if it could be the flange nut for the guide support, like 448945.

They don't look like Festool parts. Could they be from something else?

They are well-machined parts and, given that I have mostly festools in my shop, I can't place them on another tool. 
Any ideas will be welcomed!

I was going to ask if this was on-prem work and if you had work mates... They might be having a go with you.

But if it is in your own shop, that might not hold!

I did check my CMS and don't recognize those parts either.

Cheers. Bryan.
