Sanding Disc - 40 Grit - 150mm - Pack Of 5 - Universal Fit

A 40-grit disc is primarily used for aggressive material removal, such as stripping old paint, varnish, or filler, and for initial rough shaping of materials.

No, 40-grit is a very coarse grit and is not suitable for fine finishing. It will leave deep scratches. You will need to transition to much finer grits (e.g., 120, 180, 220) for finishing.

This disc is designed for 150mm (6-inch) random orbit sanders that use a hook and loop attachment system. Ensure your sander matches these specifications.

This pack contains 5 sanding discs.

Universal Fit means the discs are designed to be compatible with most standard 150mm random orbit sanders that feature a hook and loop backing pad.

No, these discs are specifically designed for 150mm random orbit sanders with a hook and loop attachment. They will not fit or function correctly on other types of sanders.

The punched holes are for dust extraction. When aligned with the holes on your sander's backing pad, they allow dust generated during sanding to be pulled away by your sander's vacuum system, leading to a cleaner work area and surface.

Ensure the hook and loop surfaces on both the disc and the sander's backing pad are clean, dry, and free from debris. Verify that the backing pad is in good condition and not worn out.

Check that the dust extraction holes on the sanding disc are aligned with the holes on the sander's backing pad. Ensure your sander's dust collection system (bag or vacuum attachment) is clear and functioning correctly.

This is expected with coarse grit on tough materials. Ensure you are not applying excessive downward pressure, as this can prematurely wear out the abrasive. Consider if a finer grit might be more appropriate for the specific task if wear is faster than anticipated.

The 40-grit is designed for rapid removal. If it's removing material too quickly for your control, reduce the pressure applied to the sander. For finishing, switch to a higher grit sandpaper.
