sandy said:After a few waterline / electrical wire close calls, I now only cut through dry wall using my Fein Multimaster with a straight blade which allows me to cut straight in, rather than "sawing" through the drywall. That way the depth of cut is only the thickness of the drywall. Also, I make a small opening, and then look inside with a flashlight and mirror to make sure I know where the lines, studs, and fire stops are located. I have lots of Festools, but for the initial cut into drywall with unknown interior, I only use the Fein.
Ditto!
