Cutting a hole in sheet metal

Bimetal hole saw will work great. To keep it from trying to ‘walk’ , after drilling the pilot hole replace the bit ‘I am assuming 1/4”with a smooth 1/4” rod.
I used the smooth section of a long 1/4”grade 8 bolt.
When cutting hole use a little thread cutting oil and operate the drill slowly. A hand drill can do this easily using minimal pressure.
Let the saw cut, don’t need to force it, be patient. I have cut holes in the hood of my car and 3/8” metal doing this.
