Adjustable Circle Cutter
Does anyone have one of these cutters?
Product Search
If so, what size is the drill bit in the centre? 1/4"? Is it a good cutter?

G'day Mike john,
I got one from McJing as below which has a 1/4" centre pilot.

It does a fair job, though not as good as I'd hoped.

I haven't tried the double-sided cutter like the one you've shown, but I did have the single sided cutter and it worked for awhile(about 12 wheels worth) and then stripped out and won't tighten down anymore, so it just spins...useless. The double-sided cutter would probably be more balanced and might work better..but the other issues are that it's a heckuva lot of fiddling and adjusting, when you reverse the blade so the taper is to the outside, which you have to do for wheels, it wastes a lot more wood than a hole saw.
I finally gave up and have started buying Lenox holesaws. They come with a quick-change mandrel, so buying extra cups of varying sizes doesn't cost too much. Dunno if they are available "down under", but there's probably an Aussie equivalent company.
To answer your other question though..I think most of them do come with 1/4" pilot bit.

That looks like a good way to maim or kill yourself.
go buy some good quality hole saws.
Yes we do have quick release arbours(dunno how to spell that) in Australia. Suttons seem ok as hole saws had mine for 20/30 yrs still cutting.

This type of cutter works good if you have a lot of time to spend to work with it. Only good thing- in doesn`t burn-on wood like hole saws sometimes do. And holding workpiece with hole saw is much more easy.

I did buy a set of hole saws and I struck a problem. I want to make a wooden spoked wheel. The tyre is od 3" and id 2-1/2". I have a hole saw that gives an od for the rim of 2-1/2 but with wobble and saw movement I end up a 1/16 to 1/32 under that. So my rim is not a tight fit inside the tyre. A picture explains it better. This is my rough drawing below.
So I thought a circle cutter. Maybe this type is better:
Heavy Duty Circle Cutter - Rockler Woodworking Tools
Know where I can get this in Australia.
Any other suggestions?

Suggestion.
Cut the tyre with hole saws that you have.
Mark the centre of the rim, use a compass mark the outside edge of rim, use your hole saw cut out inside edge of rim, on the bandsaw cut nearly to compass line, sand to line on the disc sander, bash / tap or gently press rim in.
I think nrb means anyone of them.

Clarence...on say a 3" OD wheel..you need a 3 1/8" holesaw to give you the exact 3" wheel. This 1/8" accounts for the saw kerf of 1/16" on each side. And I'd definitely rule out the circle cutter and use the holesaw for the type of cut you posted. The circle cutter has a straight side and a 45 degree angled side, which leaves a pretty big "kerf". Oh..and the useless circle cutter I got was General Brand that was bought from Rockler. Same as most US sites I've seen.
