Bosch delta sanders come in various shapes and sizes. But they all have one thing in common: they're compact, powerful, and every do-it-yourselfer can easily sand even the hardest to reach corners. The triangular sole allows you to go in all directions and narrow windows, stair treads or drawers are also stripped of their old lacquer or paint layer. The delta sanders from Bosch are available on battery or mains power. In addition, the sizes of the sanding pads and the composition of the set vary. For example, some Bosch delta sanders also come with handy cases and multiple sanding sheets for different materials and applications.
