Ok, if its an inch thick, a tank cutter is no good..
These are though:
Available in 44mm (closest you will get) from RS item number 315-5951 and are £8.60 each, not supplied with guide drill/arbor though.
Arbor to suit is item 315-5872 and is £11.55

Because they wobble With holes saws you always have to use one 1 mm under unless you are working at a really slow speed.
The B&Q orange bi-metal ones are OK -- I have used them on 4mm steel plate to make really big holes.

Expensive hole saws , Starrett or similar available from electrical wholesalers. Make sure you get an arbour with it they tend to fit about 4 or 5 saw
sizes then you have to change arbour. Used sensibly they get through anything and with even a cheap pillar drill can be set up for fishmouthing round
tube.

Only one big issue surely, he's cutting ally, rotobroach won't mag onto that! (unless you stick a heavy steel platew on top I suppose and
rely on that for positioning)

Buck and Hickman (buckhickmaninone) do all manner of holesaws.
By the time you put a 44mm holesaw through, then dress up the inside with a half round or round file, the hole is more than likely to be 45mm or
bigger. You may be best to go through with a 43mm, and take the remainder out with a file.
Bush engineering at its best!
