Bosch 2608901177 EXPERT S471 Standard Block 97 x 69 x 26 mm, Medium 20-pc

Lasts up to 5x longer than Bosch C420 Sandpaper - Sometimes there’s no substitute for hand sanding
The problem was that conventional sanding sheets wore out fast, clogged, or broke when sanding curves and edges
The old solution was to buy a lot of sanding sheets, leading to high consumption and waste
The new solution is sanding foams using Bosch Surface Structure
The Surface Structure combines advanced bonding and surface coating techniques to fix the grains to the backing
It's so strong that the Bosch EXPERT S471 Standard Sanding Block doesn’t lose grit when sanding around edges and corners
It also minimises clogging and dust can simply be knocked or washed off the flexible surface
It also shapes to surfaces with even pressure
Square sanding sponges are ideal for sanding flat surfaces and 90 degree edges
The Bosch EXPERT S471 Standard Sanding Block is a revolution in hand sanding
Once you’ve tried it, you won’t look back
