3M 7100006170 Disc Backing Pad 5 Inch Hook Loop

Product Description

The 3M 7100006170 is a 5-inch disc backing pad designed to support abrasive discs during sanding and surface preparation work. It mounts via a hook and loop attachment system, allowing fast disc swaps without tools. Rated to a maximum of 12,000 RPM, it is built for use with compatible rotary and random-orbital sanders in trade and industrial applications. At 0.06 pounds, the pad adds minimal weight to the tool assembly. Metalworkers, auto body technicians, woodworkers, and general contractors use this type of backing pad for consistent backing pressure across the disc face.

This backing pad is suited for light to medium surface preparation tasks including paint removal, material blending, and finish sanding. The hook and loop mount makes it a practical choice in production environments where abrasive disc changes must be done quickly between grits or disc types. It is appropriate for both bench and field use wherever a 5-inch abrasive disc platform is required.

Compatibility

Designed as a replacement or spare disc backing pad for use with rotary and random-orbital power tools that accept 5-inch hook and loop abrasive discs.

Installation Notes

Installation is performed by threading or pressing the backing pad onto the tool spindle per the tool manufacturer's instructions — confirm the spindle interface matches before mounting. Always power down and disconnect the tool from its power source before attaching or removing the backing pad. Do not exceed the 12,000 RPM maximum speed rating of the pad. Inspect the hook and loop surface for wear before each use and replace the pad if the fastening surface no longer holds discs securely.
