time saver


what used to take me forever on the job now only takes minutes because of this demo tool. it can usually handle the job well. very happy with my purchase

DeWalt is the way to go


After owning previous demolition hammers like the Bosch which worked good, I like this Dewalt 10x better. Dewalt is a great brand that lasts long and the job always gets done
