Let' say that you have a spindle with a JT33 *male* taper. It will take a
chuck (duh!)

What if you want to use it to hold an end mill - are there attachments that
would do that (the spindle is *not * hollow so drawbars etc are out)? What
about other attachments - could you, for instance, make it to take a pulley?

I have seen one person who drilled and bored a hole in the spindle to mount
6 mm end-mills but that seems like cheating :-)

It seems to me that anything not held on by a drawbar or other means is
going to get ripped off the spindle while milling but I do not know enough
about this to say with any certainty.

The problem with milling in a drill press is not only one of the chuck
getting loose, as this could be fixed with a retaining screw as on
reversing drills. This might work for very light milling.

A greater difficulty is that on most drill presses the bottom spindle
bearing (nearest the chuck) is designed primarily for end-loading, ie.
thrust from drilling. Side loading from milling may very well cause
chattering or rattling of the spindle/endmill, depending on type of
bearing.

If space or budget is a problem the most satisfactory solution is
probably a post-type mill since these are now quite inexpensive.
These will drill very well and are not too shabby for milling, if the
loss of registry during head elevation change is acceptable. On these
machines the quill is adjusted to depth-feed the cutter; typical
quill feed range is 5" or so, any more would require head elevation
change.

This issue has been debated at great length in this group and the
general consensus has been "don't do it!"
