Abrasive material for belt sanders

Belts for the two belt sander sizes, in Rubin — the abrasive developed for softwood and hardwood, which is what a belt sander is mostly pointed at. The 533 × 75 mm belt fits the narrower machine and the 620 × 105 mm the wider one; check the size printed on your existing belt before ordering, because the two are not interchangeable. Grits run P40 to P150: P40 and P60 for levelling and removing old finish, P80 to P120 for working through, P150 where the belt sander hands over to an orbital or a random-orbit machine.
