Bosch Sanding sheets C430 - G60 - 93x230mm - Pack of 10

The C430 Expert for Wood and Paint is suitable for keying and sanding paint, varnish, filler, primer, and wood-based materials.

No, this specific model (2608605311) does not have pre-drilled holes for dust extraction. Its open-coat design facilitates dust removal, but compatibility with your sander's dust extraction system may vary.

The electrostatic coating ensures that the abrasive grits are evenly distributed and stand upright on the sheet. The 'open' nature means there's space between the grits, allowing dust to pass through and preventing the sheet from clogging quickly.

The G60 grit is considered a coarser grit, best for initial material removal or surface preparation. For fine finishing, you would typically move to higher grit numbers (e.g., 120, 180, or higher).

The C430 features a highly flexible C-/B- paper backing that is robust and resistant to cracking, even when folded.

The C430 Expert line is known for its exceptionally long lifetime compared to standard sanding sheets, due to its durable grit and clog-resistant properties. Actual lifespan will depend on usage intensity and the material being sanded.

While primarily designed for wood and paint, it can be used on some metal primers or fillers. For raw metal, a different type of abrasive may be more suitable.

Ensure you are using the appropriate grit for the material. Tap the sheet periodically to clear dust. For softer materials or paints, consider using a sheet with a more open coat or increasing dust extraction.

Ensure the hook and loop backing on both the sander pad and the sanding sheet is clean and free from debris. Press the sheet firmly onto the pad to ensure a secure bond. Check if the sander's pad is worn or damaged.

Check that the sanding sheet is applied evenly and without wrinkles. Ensure consistent pressure is applied during sanding. Verify that the sander's pad is flat and in good condition.

Ensure the sheet is not being folded excessively during handling or application. Verify that the sheet is compatible with the orbital sander's movement and that the pad is not damaged.
