Cutting corrugated sheet metal

I always used "snips" for that job.... those saw blades cost way too much money.

I use a power shear attachment that goes on a drill. Clean fast quiet precise. Its got it all!

I'm another user of backwards plywood blades. Yes it throws hot shavings, but it's also cheap, fast and accurate as long as you're careful.

I use my dull circle saw blade turned backwards. Carbide blades (which is all I use) work fine for me.
Gotta gotta wear safety glasses and anyone helping also.

Actually, Lenox makes a carbide toothed metal cutting blade that does a real good job on a circular saw. You can fly thru light gauge sheet metal with it.....just BE SURE to wear glasses and avoid the front of the saw, because the metal flies out of it.

I ran into it recently at Lowes. I was skeptical, because my experience with carbide teeth and metal was what you said.....a few cuts and all the teeth were gone. But not this one. They run about 40 bucks, but I've cut a big pile of metal with it so far, and not a tooth gone yet.

I use pneumatic shears. Harbor Freight, about $15.

ETA: I was wrong, they're $30

These "shears" are worth every penny, IMO, I love em.

They are a bit trick tricky to cut across the taller corrugations, but cut smooth sheet metal, straight or circles, like butter.

They'll cut a 8' piece of metal roofing longways, in about 60 seconds, leaving a very smooth (but sharp) edge.

One of my favorite tools.

My dad has a nibbler that attaches to a cordless drill.
It is the ONLY way to go in my opinion.
We put steel ribbed siding all around his huge old farm barn over the past 2 years.
It is quiet and efficient.
I've tried using a circular type blade and it leaves a poor edge and is LOUD!

I frame for my roof, go to the lumber yard with my measurements, cut the metal with their big shear. Done.
