Are you using a pillar drill?
You can rarely produce enough pressure with a hand drill and this cased the drills to blunt quicker.

well its sort of hard to use a pillar drill on most parts, but on the bits i can get to it was easier

i know you can sharpen bits on a bench grinder but ive been told that is difficult, and that there was a drill attachment you could buy that did the same thing
is this true?

You can buy an attachment yes.
Ive never tried one ...always sharpened mine by hand on a bench grinder.
Difficult ....no ...but then Ive been doing such things for Decades:).
