Best grinder disc for cutting metal Buying guide
When looking for a grinder disc for cutting metal, you need to consider several features. First, the disc must be able to handle the type of metal you are cutting. For example, aluminum or stainless steel require different discs. You also need to consider the thickness of the metal. Thicker metals will require a disc with a higher grit rating, or one that is rated for hard metals. You also need to consider the speed of the grinder. If you are cutting thinner metals at a higher speed, you will need a harder disc. It is also important to make sure the disc is compatible with the type of grinder you are using. Finally, make sure you get a disc that is designed to be used with a grinder, as regular cutting discs may not be suitable.
