Although many of us use our circular saw for woodworking, there really is no limit to what you can achieve if you do it correctly. Many people wonder if there is a special saw for cutting metal that can be used when you want to work with this material, and sometimes it will be.
However, it is possible to use a circular saw for wood that allows efficient and safe cutting of metal. This should only be done if you are sure that it can handle the load, the blades have been adapted to metal materials, and the speed of the circular saw will not be too high, among other precautions to keep in mind.
In addition to these small differences, you need to take some precautions and a completely different approach to working with metal than with wood. The circular saw for cutting metal is based on various methods and angles of work and contains a whole set of safety hazards that you may not know about. To ensure safe and effective cutting, we've answered some of the most important questions about cutting metal with a circular saw.
Just as there are many different types of metal, there are also different types of blades. Usually the blade specifically lists what it is intended for, so you can match it to the material you are using.
When working with metals such as copper, lead, brass and aluminum, look for cemented carbide grinding wheels, because they are non-ferrous metals. Because they are easier to cut, you can generally use a cordless circular saw to work with them, but it’s not advisable for other types.
If you want to cut ferrous metals such as iron and steel, you'll need something much more powerful than a cordless power tool with a metal cutting disc. For safety reasons, it is best if the home workshop owner tries to use a circular saw for the above-mentioned non-ferrous metals.
It's also worth considering the thickness of the material you work with, because you need something with more teeth if it's thin and has fewer teeth for thicker metals. Again, each blade packaging should specify what is best for it, including the thickness, so that you can match it with the metal you are going to work with.
These are usually measured in inches, so it may help to get specific measurements of the metal you’ll be cutting.
When you work with metal instead of wood and use a circular saw, there are additional risks that you need to watch out for. Compared to sawdust that fall off when working with wood, metal shavings are much more dangerous at work. For this reason, you need to be sure that you are protected by clothing, glasses and long-sleeved gloves.
However, most metal cutting saws have a hole for collecting chips, but it's still best to protect them. Another potential problem when cutting metal is heat that can radiate from it, not just chipped metal chips.
When the saw is operating at high speeds, which can be done when using a wood circular saw, the metal can burn quickly. If it touches someone, it will cause severe burns and will also permanently damage the power saw. Because metal can be harder to cut than wood, you need to be sure of the stability of yourself and the device. One slip while using a circular saw on metal, and there could be a considerable risk of damaging cuts.
