3M 7000120559 Disc Backing Pad Hook Loop 25000 Rpm

Product Description

The 3M 7000120559 is a hook and loop disc backing pad designed to hold abrasive discs securely during grinding, sanding, and surface preparation work. The 0.25 inch shank mounts directly to die grinders and rotary tools, making it a common choice for metalworking, body shop, and fabrication applications. Rated to 25,000 RPM, this backing pad accommodates high-speed tool operation. The firm density construction maintains a stable sanding surface, reducing disc flex and helping the abrasive cut evenly across the workpiece. Installation is straightforward for any technician or tradesperson working with rotary abrasive tooling.

This backing pad is suited for use with hook and loop abrasive discs in applications requiring controlled material removal or surface finishing. The firm pad density makes it appropriate for flat or low-contour surfaces where consistent abrasive contact is needed. Common use cases include weld prep, rust removal, paint stripping, and finish blending in both shop and field environments. The 0.25 inch shank size is a standard fit for pneumatic and electric die grinders found in HVAC, plumbing, and general fabrication trades.

Installation Notes

Installation is performed by a technician using a standard die grinder with a 0.25 inch collet. Disconnect the tool from its air supply or power source before attaching or removing the backing pad. Do not exceed the 25,000 RPM maximum speed rating of the pad or the speed rating of the mounted abrasive disc, whichever is lower. Inspect the hook and loop face for wear or contamination before attaching a new disc.
