Review on 🔩 Efficient Nail Eater Boring: Greenlee 66PT 1 by Christopher Clearfield

I also wrote a review on the shorter Greenlee Snail and will only repeat a few parts of it here. This punch is hard. I know it's supposed to go through steel nails, but I pushed it a lot harder and it survived. I used it to drill out a 4X4 wooden post that was filled with concrete. When drilling, I hit the edges and the tip of the drill bit into the concrete several times. The surprise came when I did a little research on this abuse only to find nothing. The beat was sharp like new. No damage. The tip of the screw was not damaged either. I'm not saying it should be used in place of a real concrete nozzle. It would be stupid. But if you need a durable drill, the Greenlee is for you.
