Those drywallers are here too. When I see them and thier long zip bits, I walk in with a double bitted ax. I then tell them if I have to fix or replace wiring because they cut of chewed it up this is what I will use to open up the walls to replace the wire. And I'll send you or your boss one hell of an extra bill. The ax seems to get thier attention. Have not had to use it yet.
