Is it possible put a magdrill cutter on standard pillar drill

Yep, drill adapters are available. But you will need a very low geared pillar drill to use one.

Holesaw would be my choice. Drill a suitable pilot hole first, seperatly, and fit a peice of HSS lathe tool on the holesaw arbour where the pilot drill would go. It will give a better quality, rounder hole as it wont wobble so much.

Or you could rough cut a 28mm hole, deburr and round with a carbide burr and then finish with a step drill.

When I was cutting my geabox brackets I removed the brunt of the material with the plasma cutter then finished with angle grinder and die grinder.

I would either use a hole saw or plasma plus die grinder for finishing.

Depends how neat you want the hole.

and then finish with a step drill.

32mm step drill?

It would also require drilling from both sides, if the material is 8mm thick.
