"Jobber" length drills are the most standard size and what most people have. Short ones are typically "screw machine length" used for automatic screw machines.
Somebody might otherwise use the shorter ones because they want the little bit of relative additional strength and stiffness of the screw machine length, or need a shorter drill to give them more room.

Morning Chuck!
I picked up a few items at the auction yesterday.
Question….I got the drill bit set in the grey case w/100+ bits.
They are the short ones. Are these bits called anything special? Jobbers perhaps??
The ½" and 3/8" are missing. Most of the #24 thru 60 are also MIAbut I'm not concerned with those.
I want to find replacements for the ½ & 3/8 that will match the rest.
I never have had a decent set of drill bits
The mill went for $1450 and they pulled the vise ($330), the swivel base and sold those separately.
Also they pulled the collet rack and sold that separate as well which really sucks IMHO There was one missing in the set and I suppose it was the one in the mill holding the cutter.
Where I stand right now.
I have searches out on C/L for a mill as well as e-bay and I am planning on a trip to MO in June that will include a run to Springfield for the Grizzly tent sale. Maybe I will get lucky and snag a floor model closeout or scratch & dent unit.
Thanks again for all the help>
I had a blast at the sale and also picked up a new Craftsman bench grinder for a good price.
And the big Baldor unit w/stand brought $490 and the big air compressor went for $1400
