    Save your money.
    Buy a small plasma torch put a drag shield on it then use a straight edge.

    Save more money,
    Buy the circle cutting attachment for the round holes.

    Once you go plasma you don't look back!

    Don't buy the Evolution saw. I bought one early this year for a job and have used it quite a bit. It rattles itself apart, pars are continually falling off of it, and the the cheesy plastic miter gauge/lock thing slips. The blade height adjuster also slips about every other cut. I have no tried other brands, so can't reccomend another one though.

    We haven't cut any stainless yet, mostly mild steel. I did cut some aluminum for a couple of small projects and didn't experience any problems. A light spray of PAM cooking spray on the blades when cutting the aluminum helps keep the blade clean. After normal preparation the aluminum pieces TIG welded fine. Saw blades remain quite clean when compared to grinding disks. With grinding disks you get metal chips embedded into the disk, and they can easily get transferred and mixed into the surface of other metals. This doesn't happen with saw blades, drill bits, milling cutters, or lathe tooling.

    If you don't guide these metal cutting saws and you try to free-hand cuts as you would a sheet of plywood you will tear up a metal cutting saw blade in a very short time. These blades will last for hundreds of cuts if you don't bind the blade in the cut or stop in the middle of the cut and then try to resume. The metal will work harden and dull the blade when you try to resume the cut. It only takes one bind or hardened metal spot to ruin a blade. Avoid cutting rebar or hardened metal with these saws. Use abrasive blades for this type of work.

    Do you have to change the blades of saws if you go from mild steel to stainless or aluminum so that the saw blade doesn't cause it to rust? I know you have to change grinding pads if you're going from mild steel to stainless or aluminum.

    Everyone has there own opinion of course . I work in a fab shop we have several of the metal cutting saws. Skill mags and another brand. They are ok if you take the time to clamp down a straight edge ...... Make sure you clean out the shavings trap after each use . Now I think using a skill saw with a metal blade works about the same . They both pretty much suck and are so loud . I use a track torch or my trusty burn bar and use a torch for half inch and up and a plazz cutter for 1/16 up to half . I cut some two inch plate last week with a track torch and number three tip. Then I finished making the final cuts by hand with a torch with number two tip and my helper holding a rose bud ahead of my cuts...... It looked great .

    1/8" and up is too thick for a wood circular saw. That being said, I have cut THOUSANDS of feet of 26ga steel sheeting with my makita 7 1/4 circular saw. If you can find them, the Tenryu metal cutting blades are much better and last longer than the steel demon. For wood though, every one of my saws has a red diablo blade on it.

    For 1/8" up to 1 1/2" bar grating I use my Champion metal cutting saw. http://www.championcuttingtool.com/pdf/rs725.pdf

    my only complaint is that is uses a blade with a weirdo 20mm arbor hole.

    Steel cutting saw

    I have the saw listed below, I cut 1/2" mild steel with it a lot. It will cut bigger but I haven't done it yet. The key is lock a straight edge on the edge for a guide so it doesn't bind. Blades are 85 buck or so and use the manfact recommended. It has saved me lots of time!!

    Milwaukee 6370-21 13 Amp 8-Inch Metal Cutting Circular Saw.

I got it for around 60.00 with coupon and it paid for its self already. I was going to buy the Milwaukee but it would have been almost 200.00 more. I used it for cutting 12 and 18 gauge plus 1/4" plate. I cannot complain. If you need it every day then go for a real steel cutting saw. good luck
    Mostly 1/8", but want to do some skid plates for my Jeep and those will be 3/16" maybe 1/4" no bigger than that.
