I searched around the forum for my answer but only found pieces of info so I hope it is OK to ask.
There are many ways to drill a hole in wood. You have regular drill bits, spade bits, auger bits, hole saws and others...I even saw one this morning with some type of razor blades on the bottom. I went to buy a few bits today and realized while staring at the wall...I didn't know which types were appropriate for the specific tasks to come.
So my question is what do the pro's use for the typical plumbing and electrical needs when drilling through framing members? I know they could all do the job, but what is the best/most typical used?
I saw in another thread someone said that typically a plumber uses 1-3/8", 2-1/8" and 2-9/16" bits but not of what type. I assume the 1-3/8" covers your typical water lines and associated insulating clamps, the 2-1/8" for 2"PVC, not quite sure about the 2-9/16" one.
So what I am looking for is the plumber's (or electrician's) choice for size and type of bit to be used for the following...
1/2" CPVC water supply with insulating clamps
3/4" CPVC water supply with insulating clamps
1-1/2" PVC fixture drain
2" PVC fixture drain
3" PVC stack
single 12-2 NM
double 12-2 NM
triple 12-2 NM
