whats the difference with these and the black oxide set? which is better?

Titanium bits will work for metal drilling whereas Black Oxide sets are recommend for only wood or plastic.

Do these work on Black and Decker impact driver as well ?

Yes, but an impact driver would make for a poor drill, just as a standard drill would make for a poor impact driver. Impact drivers are intended for driving screws and bolts, not drilling.

Will these fit in dcd996 20v max 1/2-inch hammerdrill?

It depends on the type of chuck in the hammer drill. They will fit in a standard Jacobs chuck, but not in a hammer drill designed for 1/2-inch diameter drill bits.
