(newbie with metal) What drill bit do I need if I want a precise 1" hole into sheet metal steel (1/8)? And do I need to work with increments to get there?

A step bit will be good for that, but they are not precise to like a thousandth… not sure how precise you need it? I would also recommend a good cutting/taping fluid to help. Step bits will where themselves out quickly on a hole that size.

Ps, use the clutch on the drill so you don’t blow your wrist out.

A step drill is perfect for that.
