So I talked to the framing company owner yesterday, he has 50 carpenters working for him. He spent over $10,000 on DeWalt 60 volt tools, including a ton of extra batteries. Batteries last half a day and he charges them at home in the evening. He has one old timer that insists on dragging a cord around. Everyone else likes the new tools. Personally, he doesn't like using worm drive saws, "too heavy". He said the 60 volt sidewinders will cut a stack of plywood faster than a corded saw.
