The PSM 18 LI cordless multi-sander is a ergomomic, and powerful all-rounder for sanding and polishing, in hard-to-reach areas and on small surfaces. The Bosch microfilter system ensures clean working. The built-in dust extraction element draws dust directly into the microfilter box provided. A powerful lithium-ion battery and charger are also available as separate accessories for the sander. Both components can be used in all tools in the Bosch 18V system. The additionally integrated Bosch Syneon Chip provides more runtime per battery charge.
