I work as an electrician in new builds. I've been through a lot of paddle bits due to nail strikes. I've tried Diablo brands, makita.etc. They all work fine. But they all fade very badly after hammering a nail. I decided to try this. It looked promising. As a realist, I like to see how things happen in the real world. I've used this on several homes and dozens of nailed wood structures now and I have to say I'm impressed. He's still strong and the beasts are nails.
