Yes DougW, it must be double insulated, as it does not have a ground on the cord. Before Milwaukee confused everybody by releasing 3 or 4 different Sawzall models, there used to be only one Sawzall available. It was hardwired and also had a ground. Maybe I should look into a non-Milwaukee brand of recipricating saw. Or, I could wait until Milwaukee releases the "Most Supreme of all Sawzalls, or any other recipricating saw for that matter Sawzall" and buy it. After all, a Sawzall that weighs as much as my Hole Hawg can't be bad. [Linked Image]
