Buy or hire the FlexiSand 1.9 if...
A single-disc rotary sander used for buffing, screening and light sanding rather than heavy stock removal, which is why floor contractors keep one alongside a belt or drum sander rather than instead of one. Its 407mm disc and 1.9kW motor put it in the same bracket as other single-phase rotary buffers sold through UK flooring trade counters.
