I bought this to use with my Dewalt Compact Hammerdrill/Driver. I also have their Compact Impact Driver, and love the easy, quick bit changes. This gives me the same quick-change ability for non-impact driving. I also bought the N131745 bit holder, which mounts at the base of the handle in place of the belt clip, and store it there, so I never have to go looking for it. It's a great combination, makes my drill/driver much more versatile!
