Plato de apoyo 3M DH-AC con cierre de velcro, 178 mm, centrado, modelo 7000086464

The 3M DH-AC hook-and-loop backing pad (178 mm) with centering is a support accessory designed for fastening sanding discs to compatible power sanders. Its 178 mm diameter provides a stable working surface that helps keep abrasive discs aligned and reduces vibration during sanding, polishing, and surface preparation on wood, metal and composite materials. The centering feature simplifies disc placement and promotes even wear across the abrasive surface.

Advantages

The hook-and-loop face allows quick and secure disc changes without adhesive, while the robust backing plate maintains flatness under pressure for consistent contact with the workpiece. The centering aid reduces misalignment and improves operator control, contributing to longer abrasive life and more uniform finishing. Constructed for repeated use with power tools, the backing pad balances flexibility and support to suit a range of surface tasks.

How to use

Before use, ensure the sander and backing pad are compatible in diameter and mounting system. Firmly attach the backing pad to the sander following the tool manufacturer’s instructions, making sure the centering feature is engaged to position the abrasive disc accurately. Press the hook-and-loop abrasive disc onto the pad with even pressure to secure. Operate the sander at recommended speeds and apply consistent, moderate pressure while moving evenly across the work surface to avoid localized overheating or premature wear of the abrasive.

Recommendations

Inspect the backing pad for damage or excessive wear before each use and replace if the pad loses flatness or the hook-and-loop surface no longer grips securely. Use compatible abrasives sized for 178 mm and avoid excessive speed or side-loading to maximize pad and abrasive life. Store in a cool, dry place away from chemicals and solvents that may degrade the materials.
