How to use

Attach the abrasive disc to a compatible 150 mm backing pad, ensuring proper alignment and secure fastening according to the backing pad type. Select the appropriate grit for the material and desired finish, start sanding at low speed to test contact, and then increase speed as needed while maintaining steady, even pressure. Replace discs when abrasive cutting performance declines or when the disc becomes clogged, and follow the sander manufacturer's safety and operating instructions.

Usage recommendations

For best results choose the grit based on the task: coarser grits for material removal and shaping, medium grits for smoothing and feathering, and fine grits for final finish. Use dust extraction where possible to extend disc life and improve surface cleanliness. Store packs in a dry environment away from extreme temperatures to preserve abrasive performance.
