I bought this in place of a separate angle drill bit, this thing works great with my Dewalt punch and lets me put screws in places you normally never get to. It's much smaller than a freestanding angle drill, but now requires two hands. The bit is also almost fully recessed in the head of this angle drill, ideal for getting into tight spots; However, removing the bit can be a PITA. Have a small nail ready to pry it out from the back.
