Lasts up to 5 times longer than standard sandpaper. Sometimes there is no alternative to hand sanding. The problem was that conventional sanding sheets wore out quickly when sanding curves and edges. They were also often clogged or broke. The only solution was to buy lots of sanding sheets, which resulted in high consumption and a lot of waste. Today, there are sanding foams with Bosch Surface Structure. Bosch Surface Structure combines advanced bonding and surface coating techniques to fix the grit to the backing in the best possible way. It is so strong that the Bosch Expert Combi Block does not lose any grit when sanding on edges and in corners. Clogging of the sanding sponge is also minimised, as dust can simply be tapped out or washed away.

There are also moulds for even pressure on the surface. Thanks to a rounded edge and a sharp-edged side, even hard-to-reach areas can be easily reached and sanded with this sanding sponge set. The Bosch Expert sanding sponge Combi Block is a revolution in hand sanding. Once you've used it, you'll never want anything else.
