I was slobbering over the latest Lee Valley catalogue and notived that they are selling a drill chucks for mounting in a lathe. What can you do with that that you could that you coul dnot accomplish with a drill press.

While I'm at it: theu sell pepper grinder kits. That looks like a good little project. How on earch do you drill a hole 12" deep (an accurately) ?
The reason you use a drill bit in a lathe is convenience. You already have the work in the lathe so you don't have to remove and then remount it - probly other technical reasons as well.

You'd put it in the headstock to use as a tiny chuck.

Note: if you can find one that accepts a draw bar, get that one. You'd put it in the tailstock to drill centered holes in whatever's mounted in the headstock.
I have a morse taper for my drill bit chuck and use it all the time, mostly on the tailstock..
one example of use would be when making small jars, boxes, vases, etc.. I true the wood, put it in a chuck or on a faceplate, then use a cheap fornser bit to drill the proper size hole to the approximate depth needed..
I could do this on the DP, but I'd have to either drill the stock before turning, which not only implies a high degree of turning accuracy, and also force me to KNOW what I was going to turn before I started, which takes a lot of the fun out of it.. or, I could turn the object round, build a jig for it and drill it on the DP..
You can also mount the taper on the headstock to turn small things... especially handy if you want to convert an old screwdriver to an awl or something... or taper small dowels without using the DP and working with your head held sideways.. lol
I use a morse taper drill chuck in the headstock for turning light pulls - I drill the blank through with a smallish bit (3mm), and then counter-drill one end to a depth of about 1cm with an 8mm bit. This gives the hole that the knot in the string goes into.
I have got a countersink bit with the edges ground off that goes into the wide hole (and in the drill chuck) that I use as a drive, and turn the pull between centres that way. It means that I can cut right up to the hole (as the shank of the countersink is narrower than the hole) to get a decent finish.
