Backing Pad 3M 7000028500 125 mm for hook-and-loop sanding discs

3M Backing Pad 125 mm for hook-and-loop sanding discs is designed to provide a stable interface between a power sander and abrasive discs. The pad accepts 125 mm hook-and-loop sanding discs and secures them for controlled material removal and surface finishing. It is suitable for use with sanders that accept 125 mm backing pads and aims to promote even pressure distribution across the disc during sanding operations on wood, metal, and painted surfaces.

Advantages

The backing pad offers consistent disc retention through a hook-and-loop fastening surface, reducing the risk of disc slippage during use. Its 125 mm diameter provides a balance between coverage and maneuverability, enabling access to flat and slightly contoured surfaces. Constructed to withstand the rotational and flexing forces typical of handheld and powered sanders, the pad contributes to uniform abrasion and reliable sanding results.

Suitable for

• Handheld orbital and random orbital sanders compatible with 125 mm pads
• Sanding and finishing wood surfaces
• Surface preparation and paint removal on metal and coated substrates
• Intermediate sanding between coats on painted or varnished parts

Key specifications

• Pad diameter: 125 mm
• Attachment type: hook-and-loop (Velcro) surface for fastening sanding discs
• Designed for powered sanders accepting 125 mm backing pads
• Suitable for use with a range of abrasive grit sizes for sanding and finishing

How to use

Attach a compatible 125 mm hook-and-loop sanding disc to the backing pad by aligning the disc and pressing it firmly onto the pad’s fastening surface. Secure the backing pad to the sander according to the sander manufacturer’s instructions, ensuring the pad is centered and tightened. Operate the sander at the recommended speed and apply steady, even pressure while moving across the workpiece to avoid concentrated wear. Replace discs when abrasive performance declines or when the disc shows significant wear.

Recommendations

For best results, match abrasive grit to the task: coarser grits for aggressive material removal and finer grits for finishing. Inspect the backing pad periodically for wear or damage and replace it if the fastening surface no longer holds discs securely. Follow the sander manufacturer’s safety guidelines, including using appropriate personal protective equipment and recommended speeds for the abrasive used.
