Can anyone tell me what these drill chuck arbors are used for?

I bought them on ebay thinking they were something else.

here's the auction listing.

Thanks for helping a newbie metal worker hobbiest.

The short tapered end goes into the chuck. That, in my limited experience is
usually a Jacobs Taper. You have to measure it and find out which JT it is,
and use a chuck that takes that taper size. The Morse Taper on the other end
has to be matched to the drill press spindle. The adapter normally stays in
the chuck and the long tapered Morse end would be removed from the spindle
with a wedge shaped tool . You could then use a different chuck or use bits
that have a morse taper and fit directly in.

Find out what size Morse Taper your drill press is and see if they match.
Most home shop drill presses should be MT 1 or MT 2.

Ah - so I probably didn't need these - well - at least I didn't waste
but 9.99 on them.
Maybe someone else could use them. If you need them, let me know
otherwise I'll re-list them on ebay to try and recoupe some of my money
back.

Thanks, I don't need any right now. If you can determine what the tapers
are, your listing will probably be more successful. Check out

What ATP told you is correct, but not complete. Most lathes also use a
Morse tapr in both the headstock and tailstock, so these could be used to
mount a Jacobs chuck on your lathe, if you have one. If, as you say, you
are a beginning metal worker, there could be a lathe in your future, so you
might consider keeping them.

If you really want to get rid of them, I'll pay your cost, plus your
shipping, plus whatever shipping would be to get them to me.

BTW, I am not a machinist--I am a woodturner. These same tapers are widely
used on wood lathes, if that info is of any use to you.

Thanks - yeah - I do woodwork as well, but no lathe work (yet). Just
got a southbend 9" lathe on saturday and have to get it cleaned up (it
was free and has some surface rust, but it does run and turns pretty
quietly).

I guess I'm going to figure out what tapers they are and look at the
tapers in the lathe and see if I can use them.

Thanks for the info

Those are likely Morse taper that slide into tail stocks and such.
The short end - are likely jacob tapers - for Jacob chucks.

When a chuck is bought, you also buy the taper to match it (there are a number of sizes)
and the taper that matches your lathe or tailstock (used on Grinders and Mills).

Look at tool catalogs - www.mscdirect.com is only one - J&L Enco and Grand tool are others.
Websites are sometimes a help in learning - indicate what is needed and what it is.

As another newbie, I'm confused by the above. I thought lathes used the
Morse tapers in the tailstock only and tapers like the 5C, etc. in the
headstock. Wouldn't a Morse taper be too small for any collet work in the
headstock?

No. Morse tapers can be very tiny, the Goodell-Pratt lathe uses a #0,
or, the biggest I have ever used is #5, which is bigger at the small
end than a 5C is at the big end. I have seen, on some models of SB
lathes adaptors that go into a #3 morse taper to adapt a 3C collet,
works well as long as the tapers are clean. Usually engine lathes,
bench lathes have a morse taper spindle, most turret lathes or semi
automatics will have a collet taper, which is usually proprietary and
with the small end of the taper forward, to fit into an adaptor or
nosepiece. Smaller turret lathes, ones made more for precision work
rather than mass production will use 5C or similar but there are no
hard and fast rules. In production work, 5C and similar collets
aren't the best if overall length has to be held tight, they pull away
from the stock stop to lock. Regular turret lathe types push out,
against the stops, hold lengths much more accurately. Different
strokes for different folks, there ain't no "one size fits all".

Some have 5C, like Hardinges. More have 4-1/2MT or 5MT, or
adaptations of those, which are plenty big enough. Mine has a
modified 4-1/2MT, and uses an adapter to convert to 5C. This is
common. Adapters are readily available from Royal for lots of tapers.
In order to use 5C collets, you need a spindle bore at least about
1-3/8", a closer which fits through the spindle bore and engages the
external threads on a 5C collet, the adapter from your spindle taper
to 5C, and the collets.

Normally, Jacobs chucks would be used in the tailstock.
