Anyone use a "Metal Circular Saw" for cutting Tray?

[i=p/u]

Battery grinder with Bosch blades.

The airconditioning company use hilti with cold cut blade and is excellent for strut. but as said I think the rpm is lower than the milwaukee circular saw which I bought.

They blades cost around £100+

Might be a bit late but hers my experience in cutting metal, either tray or trunking.
The best saw to cut metal is a ....metal circular saw, mainly for the guards then for the rotation speed. Using a regular wood cutting saw will throw all the waste literally in your face. Been there, done that and its not the best experience.
Now, if you are a dewalt person, like I am, you're stuck with their 373, decade old, brushed motor metal saw, which is antic but still better than a wood saw. For some reason, dewalt still didn't come up with a brushless motor saw.
But then you have Makita, Milwaukee and even Hilti I think, which they have the latest generation brushless motor metal saws.
Personally I use a dewalt jigsaw with a metal blade, for a big big majority of the cuts. Adaptable speed and way cheaper blades compared with saws. The only problem was with the compartment dividers on the trunking, but what the jigsaw blade cannot reach, I finish it with either a hacksaw or even a pair of tinsnips.

Hope it helps...

I have an oldish Makita 110V metal circular saw, but rarely use it. It's a great saw, but is overkill for most of the cuts I make - grinder with 1mm disc is quick and more than adequate.

I guess a lot depends on exactly what you need to achieve, but agree that wood tools aren for from ideal when it comes to cutting metal.

More and more sites in London now forbid using of hot work tools, like grinders. In this case, a circular saw is the best tool you could have.

So milwaukee we need blades for cutting soft steel safely at 5000rpm.
