It is like a bigger mill,
unscrewed the draw bar a little
and hit it with a piece of
aluminum and hammer. It came
loose. It is a #2 Morse with a
threaded hole of 10X1.5 MM. the
other end had a chuck on it at one
time. The mill is an older Harbor
Fright model. I got it at an
estate sale for $125 and came with
two chucks with it. I can take one
of them off and put on the shank.
Now to find threaded shanks for
end mills.
Thanks to everyone.

A 1/2" shank is about as big as you need on smaller mills. You may be able to use a 5/8 endmill with a 1/2" shank. I have a couple in my stash, but not sure the smaller mills can drive them adequately.?

Re: Central Machinery micro mill model 47158
I could get a different drill chuck adapter or
ER-32 adapter, but as these work I won't spend the extra money on
that.

I ordered my new mill with an ER-32 chuck and
set of collets.? I also have a drill chuck for it and use that
when I have to change bits a lot, like center finder to drill to
countersink...
The mill itself has an MT-4 spindle.
Funny thing, the drill chuck and ER-32 chuck use different
diameter drawbars.? Not a big problem, just odd to have two.

Re: Central Machinery micro mill model 47158
The manual on the internet archive lists the spindle as #2 morse.? Looks like there is a drawbar, item 77 in the exploded view.

Re: Central Machinery micro mill model 47158
I couldn't find that model number on the Harbor Freight web site - what is that machine?
?
If it's a mill or "mill-drill", you may have received a wedge-shaped chunk of steel with the other accessories.? After loosening the drawbar, you can insert this through a slot in the side of the extended quill, where it should traverse just above the top end of the Morse taper of the chuck or collet.? Tapping it gently will dislodge the chuck/collet from the quill - make sure you're ready to catch it when it falls.

Central Machinery micro mill model 47158
Thanks for letting me join.
Picked up a Central Machinery model 47158 sold by Harbor Freight. What is the thread dimension of the draw bar and how do you release the spindle?
Thanks,
