do it as well as you can,but learn to do it better
looks a good deal .. might need to take a look at one of these
-- be good for sheet cutting (as in mild steel plate/sheet - 3mm upwards)

There is a specific shaped steel blade for the Evolution saw. I had one to chop up the old 3mm steel oil tank.
Worked OK to cut out some 6mm steel plate yesterday.

No it's not, the tips are a differrent shape to ones I have. Your pic looks like a wood cutting blade but the actual tips have been altered in cross section.
Here's a couple of pix of mine, but I have to admit the saw is not the latest version.

That’s one for stainless steel bud . The dark blue ones are steel . I’ve not seen one the same as spurrys onemore likely to be this 60 toother I'd've thought

Spurry’s one is the ‘basic’ one, more for cutting wood with nails etc, or small amounts of steel.
The blue one has the same teeth (negative rake) but more of them. For steel
Green is aluminium.
There are (or used to be) Chinese versions available. I have stocks of the 254mm version which fits my Makita battery saw. Evoloution blades are pretty pricey.

Had a load of panels ,50m insulation and tin both sides m,cut with petrol disc cutter with metal blade ,no probs

I looked into that but was advised againstit because for cold cut it needs to travel at a different speed or the filings stick to the panels and rust

surely the ridge is going to be flashed so no exposure to the wet stuff ?

They will stick to the plasti-coat and you will have a brown spotty barn

Yes all flashed but the spits of metal stick during the cutting process to the outside if hot cutting and then rust in the weather .

I was just about to put a thread up about this exact subject, but did a search first and found this. I have a load of Kingspan insulated roofing sheets to cut (nicely) and am looking at options. 40mm sheets have approx. 71mm overall dimension Seems the mains powered Evolution saw and rail as shown above is best option, but I need to get a better generator or power onto site first.
I have a Dewalt 54v DCS579 which will cut 61mm, so I might be better off just finding a suitable metal blade that fits that. I think the quite rail will reduce the cut by 2-3mm so might be quite annoying in practice though and need double cutting. This is the only dedicated composite blade I can find.
I missed out on a nice auto start Deisel Stephill silent generator the other day. I may keep looking. Or just pull my finger out and get power into the site temporarily with a 6mm Artic flex. .

I think wood circular saws spin at a different speed to ones intended for metal.

Hmmm. Had not considered this. Evolution 210mm mains one runs at 2800rpm. Evolution Cordless (smaller 190mm blade) runs at 3500rpm and my Dewalt DCS579 190mm runs at 5800rpm
That is a big difference. I need to get power to the shed anyway, so think I am going to throw in a 10mm SWA as a temporary single phase supply which should sort me the next 10 years - so the Evolution mains Saw probably best as it will cut in once pass, and be cheap enough that it can go on shelf for one day in the future. I dont really want another battery system.

You may well get away with that for a 40mm insulated sheet , mine are 60mm so roughly 90mm cut and the 230mm disc I have won’t it that . I may have to accecpt I need to cut from both sides

Would a hand saw not finish the remaining depth of insulation?
