Drilling 1″ hole in sheet metal – but the drill won’t sit still – what can I do?
I have these shop lights made out of thin metal that came with a plug in cord. I am removing that cord and hard wiring them in. I bought a 1″ hole saw that is appropriate for metal – but it just slides around on the surface “D-oh!”
How can I get these holes into the metal (the small hole for the cord is not big enough)
Tips for the drill, as well as alternate ideas are welcome.
my dad would have used a centre punch… like these guys all say.
How thick is the metal? If it’s not too thick, put a piece of wood behind it, anchor it to your bench and take a 6 inch spike and hammer the hole through. Of course, if the metal is too thick, you will have to use the drill.
