Morse? B&S9? Other taper?

Ultradog MN · Apr 6, 2021

I saw these at an online auction?
They are described as Morse Taper end mills.
I'm wondering if they might be B&S 9.
Only one photo on the auction site so I contacted them. They said they don't know what they are but sent another photo that shows the threaded hole.
Too far to go and inspect them.
Any educated guesses what they might be?
I could use them if they're B&S9.
Thanks

No reference to mill dias, so who knows. Millions were made with B&S 9

Standard Tapers

Have fun

It's hard to tell. But, unless it's an optical effect, those tapers look rather shallow. They might be B&S. But without anything to be used as reference for dimensions, I'm unable to establish which B&S taper.

Either bs 7 or 9 it looks. Don't know how I can tell but I think that's #7. I'd be asking the seller to read off the shank for me.

Morse were made with drawbar threads, too.

Good chance its a MIXED lot.
