    Seems to be a quicker, easier and straighter way versus a typical jigsaw or angle grinder.

    Thing is mental fast...



    Would this cause cowling to flap about too much when being cut?

    Would it cause the ends of the metal to bend?

    I have an Evolution multi-purpose saw and when cutting thin metal there is a risk of the massive teeth on the blade bending the corners of the metal sheet, especially when its not laying flat on the mitre saw base whilst being cut.

    I've used one at work a few times on Unistrut and MF stud/top hat section and they work well enough on crosscutting - quicker than using a cordless angle grinder or jigsaw and far, far less sparking. On "rip cuts" of top hat I found that they have a tendency to bend the edge of the metal slightly which is no big deal (because it can be bent back and the MF stuff will never be seen). On thicker Unistrut they just cut, and cleanly, too. I think the MF stuff we use is about 0.8 to 1mm thick galvanised steel

    The big plus of the saw is that it runs relatively cool and doesn't spark like a grinder - so most sites will allow you to use them without the need for a hot works permit. Maybe not much to you, but fires started by sparks from grinders (including Stihl saws, etc) are far too common, and being able to cut metals without the need for an extra induction, extra RAMS. hot works permits (which can take up to 7 days in some places like shopping prencincts), fire extinguishers, the need to wait 1 to 2 hours (depending on site rules) before final inspection (to check for fires, smouldering, etc) and so on are major considerations to many. My insurers certainly don't like me using a grinder and surcharge me every year because I use one from time to time.
