I bought this as a backup to the other kit being how well the other one i had worked i wanted that extra hand so i do not have to keep swapping out bits all the time. This came with a small stock of drill bits good for sheetrock plugs piolet hoes in wood and over all general perpose activities. the screw bits are a standard set nothing extra there. All in all the bits seem to of held up to abuse in my wood working shop and havent stripped out yet so i dont predict this doing it any time soon. The battery life is roughly a few hours on heavy use. Light use you can get days out of it.
I am very pleased with this drill and the variable speeds and tork adjustment work wonders. all in all i can say i can reccomend this to any home owner.
