I've never seen the need for a 1.5" hole for a R/O system. Double check the directions.
These are for knockouts in electrical work but would pop right thru a sink I think. They will cut #10 gage steel. That’s about 1/8 thick.

A good quality hole saw made for cutting metal will also work or the step drill Neal posted above.
DO NOT use that wood bit you posted the photo of.
Hmmm, so after drilling change to a stone like the ones made for a Dremel and grind out the last 1/16. Yes 1/16th all the way around = 1/8"bigger.It is 1.5"

I've never needed a 1.5" hole for a regular kitchen faucet let alone an R.O. Usually 1 1/4" is more then sufficient. Do me and yourself a big solid and size the hole up with whatever you decide to make the hole with. You can always make the hole bigger but smaller is more difficult.
You only have to measure the bit that would go thru the hole.
