Circular Saw Blade
Hi All,
I have a limited application cutting 25mm steel plate for a small project.
The question is, what brand of metal cutting circular saw blade should I go for, and where can I get it?
TIA

You can get blades for circular saws to cut sheetmetal but I have not seen any for cutting plate.
If a circular saw is your only option then and abrasive disc/s would likely be your bet, maybe try 5mm passes
rather than a full depth cut and clamp a guide on the plate for the saw to run along.
cheers, shed

Thanks Shed, I am not a metalworker, however I have seen various utube videos showing thick plate being cut, hence the question.
What I really need is a reasonably flat cut, and I do not think that an abrasive disk would achieve that. It's times like this that a mill would come in handy.

I just googled this https://www.milwaukeetool.com/power-...corded/6370-21
they reckon it will cut 19mm steel, 10 mm shy of your target.
Then there was this one "Kacey Cuts 1 1/4" X 5" cold rolled steel like butter using her Evolution Evosaw230!" https://www.youtube.com/watch?v=JcexM8jR3WU
I would think that the blade speed on these saws would be considerably slower than a woodworking saw

What sort of lengths of cut do you want to achieve?
You do say a small project.
The Evolution Steel saw uses a 2700 RPM motor and their Drop saw uses 1450 RPM.
It's optimum cut is 1/2"
If you put that blade on a conventional circular saw I'd say it would not last too long.
I've heard of the brazing on CT teeth melting and the teeth ricocheting around a shed.

Looking to make/trim two (2) plates of say 40cm x 30cm. I currently have two (2) plates a little bit bigger than this to work with.

I'd be looking at an oxy-acetylene type of circular saw.
Seriously, if I had to do something like that, I'd be thinking about putting it on the mill horizontal arbour with a carbide slitting saw.
Maybe something like this Slotting Saws | Travers.com

cava
Take the good advice given by the people above ,please!
Using something like a normal power saw,that is not suited to the task you risk having an accident. Power saw accidents can be nasty.
Use the proven and demonstrably safe equipment made to do the job. Do not be a cheapskate and try to cobble something up unless you are very experienced and knowledgeable about equipment and machinery.
Yes! I am probably known as the the safety nazi around the place but DIY has a history of people who tried the cheap and a dangerous way and went to hospital for their trouble.
Please! I urge you,spend the money on either buying the proper kit or get it done at an engineering shop.
Either way they are cheap compared to a hospital stay.
Some of the uTube vids are no help either as too many run equipment with out proper safeguards.Look at how there many run angle grinders with out guards ,for example.

How about you tell us where you are and if someone here can cut the pieces to size for you? Even a decent sized bandsaw can manage those dimensions.

Ask SimonL to see if that fits on his bandsaw. He's very near you. He also has a mill to do it otherwise....
