Until now, two tools were required: One for polishing and one for grinding. The 900 MPS can carry out both tasks. You’ll be amazed how flexible, powerful, and versatile it is. The main attraction of the 900 MPS is that its two-speed gear enables the conversion of its large motor power into a permanently coupled rotational movement. When it is switched on, it ensures increased wearing for rough grinding and optimum polishing results. When it is switched off, free rotational movement enables fine finishing work. The integrated suction turbine with its practical dust bag is a great feature. Without disrupting your work, it keeps the work space clean since it sucks dust inwards through the grinding disk.In just one movement, you can exchange a grinding plate with a grinding disk for a grinding plate with a polishing pad. When purchasing the 900MPS you also receive Two-component soft handle, G80 sanding sheet, dust bag, professional carrying case.
