The idea of quickly changing bits is great. It works for the screwdriver bits, allen key bits. But, unfortuantely, this does not work for the drill bits. Within 5 minutes 2 of the drill bits I was using snapped in half. I am afraid to use any of the remaining drill bits. My reason for getting this rapid load set was so that I would not have to buy 2 drills and I could switch quickly between drilling and using the screw driver. I have a choice now to go any buy more non standard drill bit attachements for this kit (which could break again)or buy a second drill. I rate this as a failed impractical attempt by Dewalt who make pretty good tools on the whole.
