Compressed air eccentric sander

Air-driven random-orbit sanders, for shops already running compressed air and for spray booths where an electric motor isn't wanted. Stroke length is the specification to choose on. 2.5 mm on the small 77 mm machine is for detail. 3 mm is for final sanding of filler and for blending zones and roundings. 5 mm covers coarse and intermediate work on flat surfaces. 7 mm removes material quickly. The pads use an M8 thread rather than the tool-free fitting of the electric machines, so check before ordering abrasives and pads.
