Metal cutting circular saws are the same as regular circular saws but they're designed for cutting metal (hence the name). They're identical to other circular saws but the difference is that their entire designs are geared towards processing metal hence they become the only choice for professionals who do metal work as a full time job. It’s possible to use a general purpose saw to cut metal but that's only going to hold you over for so long, and you'll eventually have to branch out to a real metal cutting saw. These saws will provide clean cuts for metal without overheating and they can handle the heat buildup like no other saw. This is what they're the only option. Fortunately they're not a lot more expensive than standard circular saws.
Why Pick Metal Cutting Circular Saws
Metal cutting saws should be picked over regular saws because they're capable of handling heat and they are basically immune to high temperatures. This is why they're suitable for cutting metal and all that heat buildup is neutralized, allowing you to make the cleanest cuts while operating with the same efficiency as any other circular saw. If you use the circular saw in the past their most common application is for cutting lumber but they're also popular in the automotive and construction/interior industries. People use them all the time to cut metal sheets and roofing and there also favorite in the household. If you find yourself cutting a lot of metal you can replace your default circular saw with one of these. There is no metal sheet that you won't be able to cut with the saws on this list. They are also affordable enough that you can purchase them for under hundred dollars and they would be perfectly suitable for cutting metal.
Faster Metal Cutting
The main reason you should opt for the saws over general-purpose saws is because they tend to be slower than general-purpose saws. You would think that higher RPM = better saw but the opposite is true for cutting metal. The average speed for metal cutting saws between 3000 and 4000 RPM which is a bit slower than regular saws. You need slower speed in order to cut metal because metal tends to be stronger than most materials and you need something that will keep you safe when you're cutting thin sheets and won't cut your hands. All the other saw types fail to deliver. Metal is more delicate and the tools necessary are different. You don't want it too slow where the blade won't engage the metal, but you don't want it too fast where it rips it to shreds - you need the sweet spot and metal saws are built to provide that.
Metal Cutting Blades
The blades that you'll find on metal cutting saws are different than general-purpose saws because they require a different way of cutting. The blades are designed to cut at a slower RPM as to penetrate the metal material and give you accurate cuts without wavering and/or aggressively ripping it apart. This is why you need something that can apply consistent pressure but do so at a steady pace without messing up the straight line. It's similar to diamond blades when you have to cut granite or other masonry - regular blades won't cut it.
The most common blades actually use are 5-3/8" and these are perfect for metal work. You can find these for almost no money and they're even more affordable than other types of blades. Everything is affordable from the saws themselves all the way up to the optional replacement blades.
Deflect Heat Buildup
When you start cutting with a metal circular saw you can expect to generate a lot of sparks and high temperatures. If this is your first time cutting metal you've probably seen professionals using this type of saw and creating sparks on contact. Most people associate industrial work with this type of saw. This is why you need the specific blades that can process high heat instead of melting, because the metal will heat up to astronomical levels fast and if you touched it could melt your skin. If all you have is a general-purpose blade it's going to heat up two times faster than a metal-specific one. You could pull it off for only so long until it starts going dull. You get more longevity on your blades when you purchase ones that are designed for cutting metal and the housing on the parts tends to be made from better materials that can withstand high heat and work with all metal cutting saws.
The reason why should select this type of saw over any general-purpose saw is because metal is a very delicate material there requires a certain type of saw to cut. It won't take any blade you throw at it! It's arguably harder than cutting wood. If you cut wood or tiles you're still going to have heat buildup but it's not to the extent that you'll have on metal. In fact, it's the most dangerous material. This is why it's so imperative to purchase a saw that is specifically designed for metal cutting purposes instead of a general-purpose saw. You can also purchase multiple saw types and have one ready for every specific task. It doesn't matter if they're corded or cordless as long as they're designed for cutting metal.
