I'm confused. The gang box sticks out a half inch from the studs. How do you install the drywall without first cutting the hole?

the box is only 1/4inch past studs. not 1/2. the drywall will just float over the box. so when you hang the drywall, only use 3 or 4 screws- just enough to hold it in place. then use the magnet to find your box, and cut it out. then finish screwing in the drywall. This tool works great. i just did an entire house with absolutly zero problems

Will it work through osb

On the back of the box it says the following:"Works on drywall, plywood, particle board, laminated flooring, Masonite, exterior siding, cement board, tile, and slate."Thanks,General Tool

What tool are you using to cut the sheet rock i feel like a dremel would cut right through the metal wire being used to hold the magnet to the box

Commercial drywallers use drywall routers/Rotozips(large Dremels spinning at 9000rpm). But you can use anything. You will not come in contact with the inside of the box, maybe the tabs of the outside of box. The outside marker magnet is larger than the inside box magnet and spring tabs. If you are worried about even touching the outside tabs of an electrical box, set your depth on the bit to that of the drywall.

Does the electrical box have to be empty

With this kit, yes the box would need to be empty, but they also make something called a plug mark that plugs into an existing wall outlet. Of course that doesn't work for light switches. But there is always lipstick for those.http://www.amazon.com/gp/product/B00XUY9FB8?psc=1&redirect=true&ref_=od_aui_detailpages02
