With an angle grinder you can saw in metal or stone. For example, you use a grinding tool to sharpen pipes, remove burrs from steel with a grinding disc, or make deep slots. Choose a cordless angle grinder or a model that works on the power grid. Want to do small jobs around your house? A relatively small disc of 125mm is enough. Are you going to do larger jobs with large workpieces? You need a disc of 230mm to do you job. These are things to think about to choose the best angle grinder for you.
