I been a electrician for 15yrs. As long as I can remember I’ve used the Greenlee hydraulic pump hole punch. Works great but when I saw this, I had to have it. It was a hit, and everyone had to try it. The extra outdoor junction box that I had on my truck looks like Swiss cheese after everyone had a go. Surprisingly still have ¾battery life left. Im amazed! Forgot to mention im a huge Milwaukee guy. I have alot of the 12 and 18 volt platform. Im honestly going to slowly switch over.Also that commercial is terrible. It shows the hole punch making a very very deep hole. Impossible!
