As for the wall penetration of LP gas piping construction

I use it in the wall piping piping construction of LP gas. The hole cutting work was able to be done quickly with sharpness. Work material in the core could be taken out smoothly. I have only used it 2 to 3 degrees yet, so I'd like to check on wear and durability next time.
