Cutting Metal siding - saw options?

I'm putting up metal (steel) siding, and the manufacturer recommends a metal blade:

Tenryu PRF-18548BW STEEL-PRO 7-1/4" Steel Cutting Carbide Tipped Saw Blade

but the blade specifically states 'slow dry cut' saw. A major portion of the siding I have to cut is angled as well.

Any general recommendations?

Also, I recently installed aluminum soffit, and cut it with a reversed blade on my handsaw. I made a simplified cutting jig based on the plans on this page:

I'm guessing I can't make something similar for steel?

In a pinch I have used a backwards blade for cutting thin steel but it isn't the nicest cut, You'd be better off using a blade designed for cutting steel.

Use the blade they recommend or a comparable blade and cut slow. Do not turn a blade around or use any other kind since you need a ferrous cutting blade.

Yes, making a saw buck like that article shows is a good idea. It will just need to be altered if your siding is any thicker.

I am planning on buying the recommended blade (and running it in the direction as indicated by the mfg). But can I use a regular (hand) circular saw? I found a 7 1/4 5800RPM saw, but that sounds "fast" to me even though the blade supports that speed.

I reversed the blade for the aluminum as I didn't need a super clean cut (ie, both edges of the soffit are hidden). And aluminum is so soft, I figured it would work out OK.

I found a few metal-specific "circular" saws. I think I'll go that route barring any major issues - they are priced around $100 and run at speeds as low as 3700RPM. Just need to decide on which one.

Cutting slow means not pushing the saw through the material quickly. The blade is rated for 5800 rpm, which is what about what any normal skilsaw is.

Ah, got it! This should be a "fun" "rewarding" experience. As has been the metal roof. And the soffit.
