new hybrid water heater. The 3/4" PVC was a little bigger than this one, so I used a drill to drill the hole and widen the hole a bit. All the time spent, probably 7-8 minutes. I used a 1/2" punch to power it and it cut through like butter powder. Best purchase I have ever made instead of looking for a cheap outlet I bought the right tool at a reasonable price. I may never use it again for a while, but it's sitting in my drawer ready for my next project.
