You can use a detail sander to sand tough-to-reach spots and edges. This can be stairs, window sills, or the corners of a cupboard. We have various brands in our assortment, like Bosch, Makita, or Metabo detail sanders. There are detail sanders which run on the power grid, or on a battery. Do you want to have freedom of movement when your working? Choose a detail sander with a battery. That way, you can get to work anywhere.
