For $69 I was tempted to get the Ozito twin cutter to see how well it worked but I read that the depth of cut was only 28mm which wouldn't be deep enough for the fence profile. You can get 185mm twin cutters but they seem to be a lot more expensive and not as easily available.

The steel cutting blades have been reasonably commonly available for the past 5 years or so, and I think trying to run a conventional blade backwards is just asking for trouble in my opinion. As I mentioned, the main thing you'll notice when looking at the metal cutting blades is the massive chip limiters, of lesser note is the lack of hook on the teeth.
Be prepared for a bit of a sticker shock when you look at the metal cutting blades, they will probably cost around the same as the twin cutter. However from what I've seen, all carbide is not the same, and I'd expect a quality saw blade to far outlast the twin cutter's blades. The latter of which provides no great advantage I can see over a regular saw for this purpose. If you do buy a saw blade just be careful of any plastic guards as the chips they throw are quite hot. Not red hot or anything, but will burn skin on contact. Also be careful of using them on anything like welds (for another job), as the localised hardening on the weld tends to blunt the blade very quickly. On regular metals however they seem to last quite well.
Thanks for the heads-up on the up profile of material Bob, I've only ever used my nibbler on flat stock and didn't know about that. I was very surprised at how fast they cut however, far faster than I imagined.

I am not commenting on this use of a tool in any way, but if you read your post it looks kinda funny. First you very strongly abuse the idea of using a tool for unintended purposes, then your signature line says "The person who never made a mistake never made anything". A bit contradictory from my position.

That is one point of view. Nobody ever designed something new without using different methods either.
ANYONE who jerry rigs any tool to do something that its not supposed to do is a statistic waiting to happen.

I have used a nibbler, good on flat sheet but difficult on corrugated.
One of those sheet metal blades that fit a circular saw, had it for about 30 years, works well but doesn't give as clean a cut as I would like and also makes a huge amount of noise.
A twin blade cutter, this thing is by far and away the best for cutting corrugated sheet, it is quick, light to handle, no kickback and mine at least has no trouble with depth of cut for trimdeck.Regards

I lay roof sheeting on the grass lawn for cutting.
More stable than off the ground, small risk of harm to lawn and blade, a bit quieter.
A 1mm metal cutting blade in a 125mm angle grinder is my current tool of choice. In theory the heat generated damages the protective coating, but the thin blade doesn't seem to cause any discolouring, if that's any indication. Filing the burrs off is a good idea, as it discourages rusting too.

Yeah... it's what we do, and this forum has many posts regarding re-purposing machine parts to perform a different task
As for using the blade in the saw backwards, I have seen that done in the past and it works, in a rough manner, but I would use the blade that I mentioned earlier as cutting colorbond is exactly what it is designed to do and they work extremely well
