Short and sweet but here it is:
I recently bought the Hitachi wh12dm2 impact driver at amazon for $249. Not
a gloat but I'm ok with that.
After the batteries were charged, I started driving screws. WOW! I was
driving 3" screws into hardwood with no problem. The impact keeps from
stripping the screw and even takes damaged screws out.
It has a built in lcd light to light up dark spots and it automatically
turns off after a while.
It comes with a 20 pieces bit accessory (very cool)
It drills also.
This is the best driver/drill I have ever owned. It feels very good in the
hand is well balanced.
It's a little spendy but if you are a drill nut like me, it's worth every
penny. Needless to say, I highly recommend.
