Cutting metal

[Ollie6070]

Currently using a evolution circular saw with steel cutting blade for cutting sheet steel lengths but need to change as I’m getting fed up with paying £50 for a blade that only lasts a couple of cuts so was curious as to what everyone else uses for cutting ?
Have oxy propane which can be used for thick stuff but what’s best for under 10mm ? Plasma cutter maybe?

What size blades? Cheapest I've found for mine is Amazon, £25 each tops, and on offer sometimes

I also have an evolution saw, handy for cutting box (I have sharpened blades on a bench grinder, which worked well). But for cutting sheet I have a GYS plasma - I can’t believe I managed without it!

230mm blades , bought from evolution. Thinking a plasma might be the way to go

Tonight for example I cut 14ft ( not all at once I’ve added up the total) of 8mm steel and after that the blade wouldn’t cut without forcing it

Dewalt cut of saw,Sthil disc cutter ,plasma ,9” angle grinder, power hacksaw or gas axe

You should be able to send the blades off to be re sharpened

I think you’re using the wrong tool for the job. I would get a plasma or sub out to a laser/plasma firm.

Chop saw for box, power hacksaw for solid bar and plasma for sheets.

When you say sheet steel lengths are you talking about 8x4 sheets of steel or 100mm x 10mm lengths of steel and 50mm x 50mm box iron

Today has been a 8x4 sheet, don’t use it for box or anything that fits in the chop saw.

Thanks all for the replies , plasma cutter sounds like the best solution , think I was abit naive believing evolutions website that the circular saw would cut 80metres of 12mm plate !!

Hypertherm plasma

Sorry I misread the original post.

I have a big cast treadle guillotine, perfect if you want straight cuts. Anything else, plasma. Or get it lasered. You'd be surprised how cheap it is.

Plasma cutter for sheets upto 8mm
Gas for plate
Evolution chopsaw for box section and hollow pipe
Portaband milwaukee saw for anything I can’t be arsed setting up the big saw
9” Horizontal bandsaw for cutting anything else.

there’s a company which makes blades called “metal beast” which last longer than evolutions own. Once you chip the carbide they just wander for fun.

I would be hesitant to do much beyond 6mm on a hand held evo in any quantity because you need to have the tooth angle and feed rate just right to prevent wear on the tooth profile. Also, any uneven pressure will push the blade off axis & wear the sides of the teeth. I'd probably also be using a bit of molyslip to help stop galling. Plasma is probably the most flexible solution.
