Summary: I work construction for a living, doing a little bit of everything. One minute I'll be driving self taping screws into angle iron, the next I'll be punching holes in sheet-metal. And that's before lunch. This drill is awesome.
Summary: noticably more powerfull than the older version. i'm not so sold on the pistol grip. its great when drilling down , but gets a bit heavy if screwing to walls such a s drywalling. the new chuck is much easier to use.
Summary: heavier than I thought it would be...Its a monster. I like it! it works well and comes in a carry box, has the two batteries and quick charger. Not a bad deal if you need a heavy duty Dewalt. I hope that helps.
