This may be the best tool I have ever owned - Hitachi WH 12DMR cordless impact driver. I have had it about two years...originally got to use in erecting a large metal building. Now I use it for just about any fastener that turns ! Torque is about 1000 inch-ounces. It will drive the head of a 3 inch #8 deck screw all the way through a 4 X 4...and it's easy on the wrist - no reverse torque like a portable drill.
