Best angle grinder disc for cutting metal Buying guide
When looking for the best angle grinder disc for cutting metal, you should consider the type of metal you are cutting and the type of disc you need. Some of the more popular discs for metal cutting include diamond-tipped, abrasive, and carbide discs. Diamond-tipped discs are the most expensive and offer the best performance, but they have the shortest lifespan. Abrasive discs are the most common and offer good performance, but they wear down quickly. Carbide discs are the most affordable but also wear down quickly. You should also consider the size of the disc, as larger discs can handle thicker metals. Finally, make sure to choose a disc that is designed for use with an angle grinder as some discs are meant to be used with straight grinders.
