Bosch PSM Primo 50 W Multi-Sander

The Bosch PSM Primo 50 W Multi-Sander is a corded detail sander for small surfaces, corners, edges and confined areas. Its 50 W motor delivers a maximum unloaded oscillation rate of 24,000 OPM. This output is intended for controlled detail sanding rather than fast material removal over large areas. The tool can be used on hardwood, softwood, painted wood and varnished wood. Typical applications include furniture, doors and stairs. Power is supplied from an AC mains connection, allowing continuous operation without the need to recharge batteries.

An integrated microfilter dust box collects sanding residue during use. The 600 g palm-grip body supports one-handed control in a range of working positions. A soft-grip surface and ergonomic design provide a secure hold for detailed work. Its narrow sanding plate is shaped to reach into corners and work along edges. Abrasive sheets attach with a Velcro fastening system and can be removed without clamps. One sanding sheet is supplied with the sander.
