Angle Grinder for Metal Cutting. (Step-by-Step Guide)

You can cut both soft and hard metals with an angle grinder by using abrasive cut-off discs. You will need different types of cutting wheels for ferrous (steel) and nonferrous metals (aluminum, copper, brass, etc.). Due to its handheld design and disc size, angle grinders are usually limited to a maximum of 2 ¾ inches (70mm) deep cuts.
