Rockwell spindle adapters

[gravity is unfair]

Hello Garage Journal
I just acquired a Rockwell 15-081 floor drill press.
I need some help locating a accessory part that was listed in the owners Manual they are called spindle adapters.
No 15-832 adapter with No 1 MT hole with threaded mounting collar.
also
No 150833 adapter with No 2 MT hole with threaded mounting collar.

If anybody can help me find them that would be great

those are similar to what Delta used (same part # even) and seem to be hard to find, but you can get the MT2 piece and have someone cut the JT33 threads, from what I read on some of the metal working forums...

Accessories are always nice to have, but for what specific operations and/or tooling are the #1 and #2 MT adapters needed?

the OP can clarify, but from what I saw in the catalog, it appears the chuck unscrews from the spindle, and the adapters screw in their place providing an MT1 or MT2 for other tooling. Delta's of same vintage were the same way...I found a couple threads on some machining forums asking the same, I looked because I thought little machine shop had the adapters in stock as I needed something similar for a 3-in1 mill...consensus was to buy a taper and have the threads cut...

I understand how the adapters work, but once again hoping to learn, on a small home shop DP, what operations are better performed using #1 or #2 MT tooling?

no idea. it's just a drill press (probably why they are hard to find, was rare anyone sprung for them back in the day)...OP did a drive by and never came back to the thread so I can only presume it's a collectability issue, just wanting the accessories that were available at the time regardless of their usefulness...
