With a Bosch multi-sander, you no longer have to switch between different types of sanders if multiple surfaces have to be sanded. This type of sander comes in different shapes of sanding pads, so that you can sand in corners and also work on flat parts. Bosch multi-sanders are available in the DIY segment (the green machines) and in the professional segment (the blue machines). Go for a complete set with case and sandpaper if you want everything on hand after one purchase.
