Default Re: Enlarging an existing hole in a steel chassis.

I would use a taper reamer like this obtainable from most of the usual suspects. ebay, Amazon etc. https://precisehandtools.com/tr-04-t...mm-30mm-holes/
Other options might include a step drill but that will usually cut in 2mm intervals so 22mm is nearest.
Good luck
