Sanding Discs Bosch F355 Best for Coatings and Composites

The Bosch F355 Best for Coatings and Composites sanding discs are designed to deliver precise material removal and a high-quality finish when keying and sanding abrasives, composite surfaces, varnish coats and paint. Each pack contains five discs made with silicone carbide grit bonded with fully synthetic resin on an F-/C-paper backing for consistent sanding behaviour and wear resistance in demanding applications. The discs are compatible with random orbital sanders and suitable for use on hard minerals, stone, composites, ferrous and non-ferrous materials.

Advantages

The silicone carbide grit coating provides accurate removal and fine finishing while the electrostatic open coat structure allows efficient dust extraction and reduces clogging. An anti-static closed coating minimizes dust adhesion to the work surface and the machine. The fully synthetic resin bond increases durability under heavy-duty use and the F-/C-paper backing ensures stable sanding performance.

How to use

Attach the sanding disc to a compatible random orbital sander according to the sander manufacturer's instructions. Use appropriate grit grade for the task and apply steady, even pressure while sanding. Keep the sander moving to avoid creating gouges or uneven surfaces. Replace the disc when wear reduces effectiveness or when clogging cannot be cleared by dust extraction.

Recommendations

Use with effective dust extraction and personal protective equipment (dust mask, eye and ear protection). For best results on coatings, start with a coarser grit for material removal and finish with finer grits to achieve a smooth surface between coats.
