The best way to put distortion free holes in sheetmetal is with a tool called a Greenlee Punch. I've see them up to 4" diameter. Be prepare to pay for them though. I've seen them at Home Depot, but if you have an electrician friend he will know what they are too.

if you buy hole saws for stainless make sure they are carbon or titanium tipped..i work in nuclear power plants all the time as an Ironworker & deal with different types of steel fabricating & building upgrades & modifications..stainless will eat up a regular hole saw before you even finish the hole.....maybe for the price you are going to end up paying for the hole saw,a local machine shop would press drill or press punch the holes for you at around the same price or even less...

I think so too. I work at a Marina, and we have to use titanium drill bits to go through stainless steel bow rails and all. Regular bits just spin after the first couple of seconds.

I have no problems with the standard bimetal hole saws in stainless. Keep the speeds low and keep it cool with a cutting oil like rapid-tap.

Lowes sells brand"lenox" they are bi-metalic , if you go slow and use 3 in 1 or very light weight (5w 20) motor oil to lubricate you can use on stainless but probably only1-2 times before no cutting left. 31 5w

I wanted to complain about this NZ slang business, but I see it was resolved before it mattered. LOL..
