What equipment do I need to use to drill a couple of 2 inch holes in a metal electrical transfer box? I have drills and a drill press. But I need to know what to put in it to cut a 2 inch hole in metal.

Hole saw

Do they make hole saw bits for metal? If so, where can i buy one? I have looked on several websites that sell tools and haven't found anything yet that I could use.
So are you saying that for a 2 inch gray plastic conduit that I need a 21/2 inch hole?
Thanks! Jeff

Use a carbide tip holesaw. It is designed for metal. Any good quality hole saw will work. Lenox makes a nice product.
