Questions about this item

What chuck capacity do I need on my drill press to run this 1/2" reduced-shank bit?

Your drill press or power drill must accept a 1/2" shank, so a chuck with at least 1/2" capacity is required.

Will this 1.0781" Silver and Deming bit fit in the same 1/2" chuck as my smaller twist drills?

Yes, the reduced 1/2" shank lets it mount in any standard 1/2" chuck alongside smaller bits.
