I find that my tin snips are not up to the the task of cutting 22 gauge (.0299) steel sheet. the sheet tends to curl up
when cutting with the tin snip. I need to cut long strips, 3/4” wide. Would I be able to cut it with a 60 tooth carbide blade? I’ve cut aluminum with a carbide blade, but don’t know about steel.

I forget that I have a metal cutting band saw. Problem solved.

Another way: run a 1/16” metal cutting disk in an angle grinder. Makes very smooth cuts, and is quite fast. I have used steel cutting carbide blades in both TS and RAS. They cut okay for a short time, but quickly dull. Might not be so bad in metal that thin, however.

Bandsaw will work well (I converted a 14” wood cutting BS into a metal cutter by slowing it down via jack shaft and step pulleys). I use 1/4” wide variable pitch bi metal blades and they work well on mild steel, stainless, and non-ferrous metals, except on aluminum they clog easily. I think this works because the long blade dissipates heat as it circles around, and the blades last a long time.

I use a nibbler. It blows through jobs like this. Mine is a Bosch, so I paid a lot for the name, but cheaper ones, whether air driven or electric would do the job.

I also have a Twin Cutter (two blades side by side and both turning in opposite directions). My buddy said it did a great job cutting his metal roofing.

Then there is my cut off saw, which uses a 12” carbide blade.

Both the twin cutter and cut off saw use blades designed for metal cutting, of course. Regardless, the answer is, obviously, yes, a carbide blade would do the job. My biggest worry would be holding the metal down around the blade. That may mean creating a hold down from a flat piece of ply to keep it flat at the blade.

Ron – next time you are in one of the Big Box Stores,
go to the back where they unpack the lumber.
you can pick up oodles and oodles of 3/4” steel banding
for free. you can strip the paint off with solvents or sandpaper.
a bit more thicker than you need, probably 1/16-3/32” thick
but all will be consistent in size and very straight.
just a thought.
when you say “long strips” what do you consider long ? and how many ?
