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.

Nope it is quite conviently the largest size on my step drills (from Lidl I think they were) so you can do it in one.

You're right. Should have checked mine first... 32mm.

Also (reasonably) cheap Chinesium, but it looks a lot more like the ones I've used successfully on stainless pipe and plate and available next day. I have no experience of the one in the link. Plenty of similar on Amazon, ebay, etc if you search for "32mm tct hole saw"

I did 40 odd holes in 5mm stainless with one 25mm Chinesium bit and it's still sharp!

I've used mag drill cutters in my mill and lathe tailstock, chuck on my pillar drill isn't big enough to hold a mag drill cutter

I cut around 30 50mm holes in 6mm SS with standard holesaws. Set up the Meddings Drilltru to half it's normal lowest speed and used plenty of cutting fluid. Used two holesaws.

Client wanted a 60mm hole in 4mm and 'kindly' bought in a chinesium hole saw. It just polished the surface as it smoothed out it's teeth.... Silverline IIRR.
