How to use

Fit the disc onto the sander's 150 mm hook-and-loop backing pad, ensuring the disc is centered and adheres evenly. Start sanding with light, even pressure and allow the tool and abrasive to do the work; avoid excessive force that can cause uneven wear or damage the surface. Use progressive sanding steps if moving from coarser to finer grits, and inspect the disc regularly, replacing it when cut performance decreases or it becomes clogged.

Usage recommendations

For best results, use the P320 discs as the final finishing step after coarser abrasives; keep the working area clean and use appropriate dust extraction when sanding painted or metal surfaces. Store discs flat in a dry environment to maintain backing adhesion and abrasive performance.
