It's a 1/4" jobber bit. I've used these for thousands upon thousands of holes in birch ply and HDPE. They continue to work great.

I typically don't drill much larger than 1/4", occasionally I'll run something a bit larger than 1/4", but if I get to 1/2" holes or larger I just run an inside toolpath using the spindle. That air drill I have is great, but when you put larger bits on it you can't plunge as fast.

I actually wondered this as well. Shortly after moving in to this home 5 years ago I took it upon myself to replace the old galvanized pipe in the crawl space. At the time I honestly was a lot less concerned with codes and just getting the work done because I knew that I had plans to remodel everything and this was just a stopgap. For the main supply runs I used 3/4" CPVC mostly because I felt it was easier for the long straight runs down the house. I did 3/4" x 1/2" tees off of that and adapted it to 1/2" PEX to do the connections to the various fixtures in the house. I used sharkbites which was expensive but pretty darn easy to get it done fast.

Last year, I did a remodel on the main bathroom. I hired a plumber to do the rough in. I did not really ask why, maybe just old school, maybe other reasons, but when he did his thing he took out all of the PEX and replaced it with CPVC and handed me a bag with all of my sharkbite fittings.

Now I am preparing plans for a permit to do the remainder of the house remodel. I do not plan to pay for the plumber this time. I figured if a pro plumber used CPVC maybe I should as well. If nothing else, just to keep everything consistent.
