Hi mate,
I think the type youre on about are known as blacksmiths drills. They dont go up much past about 20mm so that means your into hole cutters for that
sort of size.
What are you cutting?

Buy a set of HSS tank cutters. They will cut big holes in pretty much anything.
If you want a drill around 45mm the only ones you will find are morse taper shank ones. A normal 13mm chuck would never be able to hang on to a drill
that big, and its unlikey the drill (machine) itself would cope either.

If its thick metal you are drilling then you want one of these.....
hss
they cost about a grand to buy so hiring is the way - you may need to buy the appropriate bit though....

Yeh the arbor isnt a fat diameter. Would a hole saw not go through the alloy? What sort of thickness are we talking?

You might manage 1" thick 45mm dia with bi-metal hole saw -- if you keep well cooled and the speed right down.

I have a few blacksmith's drills in 3/4" & 1" - they're very hard to use in a hand-held domestic electric drill, and put a
huge load on the drill. You would probably have to work your way up to the final size in increments.
BTW: 'blacksmith's drill' is a good description - they're crude and not particularly accurate.
Do a Google on Tracy Tools for a cheap source via mail order (but don't use your credit card, 'cos they charge you a bundle). Send an
order with a cheque and you'll get your drill(s) back by return post - they're very good at that.

I have a few large drill bits whose ends I had reduced to 10mm in a lathe. It´s the cheapest way to go, I think.

yep ^^^^ wot he said. you need to use them at slow speed and the can jam quite easily possibly breaking your wrist (ask me how I discorverd that).
It is far saver to use a stepped cone drill - but think you are struggling to get to 45 mm.; but those are for panels really so no use for you I
guess.

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

If its 1inch thick alloy, a decent tank cutter will cope. Use PARAFIN to lubricate/cool it as it cuts. This will help to stop it clogging the cutting
edges. DO NOT ATTEMPT IT unless you put it in a pillar drill and clamp the work piece !

Hole saw, drill from both sides, nice and slow using paraffin as coolant.
ACE Cafe - Just say No.
