Pronet use an aluminium oxide abrasive, blue fired to remove impurities, for a longer lasting and clean sanding action. The knitted fabric backing allows dust generated to pass through, giving a longer working time without having to de-clog the abrasive.
ProNet has a longer life than conventional abrasives, and can be washed out for re use.
All discs are colour coded so they can be easily identified. The backing is also compatible with hook-and-loop style fixings.
