If you want to effectively cut metal using your circular saw, a quality saw blade made for metal cutting is a must. Metal is a tough material to slice through, and it is essential that a good saw blade be used to safely go through the tough medium. The good thing though, particular saw blades exist for every known medium or job—much like what we previously discussed in the Tile Saw Blades article.
To be able to select the right blade for you application, you must know how blades are named or labeled. For example, a masonry blade is obviously used for cutting bricks. A flooring blade is used to cut rough lumber, and, for the sake of this article, metal cutting blades for metal.
When looking at blades, you will instantly realize that there are a number of configurations for the teeth. Some blades have fewer but larger teeth, while others have smaller teeth but are packed together more tightly which gives a greater total number of teeth. In this aspect, blades that have more teeth cut through mediums cleaner and smoother. You might also come across carbide-tipped blades. Carbide is a tough compound in itself, and these blades, although more expensive, last longer and requires less sharpening.
For softer metals such as aluminum, brass, copper, and lead, non-ferrous metal and plastic blades can handle the job effectively. By the way, you will also come across ferrous and non-ferrous in your quest for a metal blade. Quite simply, ferrous is a term, more specifically an adjective, used to indicate the presence of iron. In this description, ferrous refers to the medium being cut—which is metal. Ferrous blades cut tougher metals as non-ferrous metals are those described earlier as softer metals.
