Longer abrasive life – thanks to Bosch Surface Structure bonding
Bosch Surface Structure creates a strong, flexible bond between abrasive grains and the backing, reducing premature wear. Manufacturer claims up to 5x longer life compared with Bosch C420 sandpaper.
Fewer disc replacements during a job, keeping momentum on larger sanding tasks and reducing waste.
Faster paint removal – with medium grit and firm pad
Medium abrasive grade targets old paint and loose coatings on wood while the firm pad maintains consistent pressure across the contact area. The combination removes material efficiently without excessive gouging.
Restoring window frames and stripping paint becomes quicker, cutting time spent on each sash or panel.
Accurate edge shaping – with square edges and firm pad
Square-edged design gives defined contact lines for sanding corners and profiles, while the firm pad resists flexing under pressure. That keeps sanding focused where material needs removing.
