What are these and what can I do with them?

[sortafast]

got these when I picked up my new to me mill. Looks like some sort of indexer deals. Are they worth anything? Can I use them on any milling ops?

Figuring out the taper is the challenge ... Brown & Sharpe #9, Jarno, BT, Jacobs, Morse, et al.

Is there a nameplate on either of them?

cant find any branding on either of them. I am pretty sure from my googling and measuring that the blue one has an ER40 collet on it. But I think that its an adaptor that is some. Its marked ETM as is the 1" collet thats in it. I wish I could find out more about them. Also, are these useable on a mill? I am thinking they came off some sort of grinder or something. Might have an op on a part that I could us one of these indexers for.

ETM is a machining outfit out of Ontario Canada, maybe it's one of their tools or old mills

I doubt it. I just pulled the adaptor out of the blue one and it almost looks like its an MT5 taper on the part that inserts into the indexer from what I can tell. Its pretty darn big, thats for sure. Now the fun of figure out the taper on the other one. I think It might be an MT3 or and MT4, but I will tear it apart and see.

Dos your mill have the gearing to tie the table to that indexer? If so, yo gan do some "interesting" work, like machine helixes

nope. the mill is an RF30 so its rather limited. Doubt I will ever be able to use either of these, but I suppose they aren't a bad thing to have laying around for one of those just in case sort of things.
