Cut steel on a regular basis? Or at all?

[bucket]

Where have these things been all my life?!!! Are they a recent development or have I been living under a rock?

Metal cutting blades for a circular saw is what I'm talking about. Anyone ever use them before? If not, I highly recommend it! When it comes to cutting flat stock, bar stock, square tube, and etc, the usual cut-off discs and chop saw aren't going to get used nearly as often.

That there is 1" steel plate. The cut was done in only a minute or so, and it's extremely crisp and clean. It also stayed remarkably cool. I figured the big drawback would be blade life, but it just keeps going with no signs of wearing out. It's simply incredible, I had to share, lol.

In the industrial world cold cut saws with carbide toothed(teethed?) blades have been around for a while, but affordable saws/blades for the consumer level are more of a recent thing to surface within that last few years.

Startrite mfg'd a lot of cold cut saws for industry

This is what have surfaced in the more recent years (although tempting do not put a cold cut blade in an abrasive cutoff saw as the speeds are different and will most likely destroy the teeth and either send them flying or completely wreck the blade)

Then there is the ones for portable saws like what you have, pretty slick if you ask me and for a lot of metal cutting is well worth it and worth having a lesser chance of setting the shop on fire...

Also make sure to give a quick visual inspection of the teeth prior to cutting as once one tooth breaks off, more will break off due to the uneven cutting forces

Yeah, iirc that Craftsman saw was maybe 200rpm out of spec for that blade, but so far it works well. I've used the blade for several smaller jobs the last few weeks and then tried it on the heavy stuff today. It just plain works. I love it!

Where do you find the blades?

Jup, been around for years. You can get blades for anything for a circular saw. Metal, Wood, Masonary and even in different variants. Fibre blades, toothed blades, fine toothed etc. I've even cut plastics and fibreglass with a circular saw.

A friend of mine picked it up for us to try out. I'm pretty sure he got it at the local Rural King.

I have had a cutoff/miter saw that has the metal cutting blade, about 15 years and still cutting clean as can be. I see that blade is a Diablo, can You give us the part number for it ?

Whoa... I knew they were out there but had no idea they were that effective; just assumed they were for tubing and whatnot. Thanks for the intel, I’ll definitely be be picking one up

And here I thought I lived under a rock. Grown men thinking the wheel has been invented and it's been around many years.

I've definitely thought about getting a blade like this. Would certainly make some jobs much easier and cleaner as opposed to using grinder with the cut off wheel. With that said, I don't see myself ever need to cut up 1" steel plate but would still be handy to use for the 1/2" and thinner stuff with a cleaner, straighter cut.

I've been using carbide tooth wood blades in a circular saw for cutting aluminum for years. Never wanted to do it with steel, but now that there are proper blades for it I'll probably give it a try.

Wear you safety glasses though. At least the wood blades on aluminum fling a ton of hot bits around. Maybe the steel one is better.

These look to be close to the same idea a diamond blade for metal in a angle grinder. Ive always wondered if they work as good as an abrasive cut off wheel. Anyone used one?

You're right, roofing and thin wall... only recently have the full on metal cutters. The new Diablo line will work even at high speed. We can't get them in Canada yet, at least not in small towns.
