Dynabrade 56180 Disc Backing Pad Hook Loop Medium Grade

Product Description

The DYNABRADE 56180 is a disc backing pad designed for use with random orbital sanders. It accepts hook and loop abrasive discs and mounts via a 5/16-24 male threaded spindle connection. The medium-density construction provides consistent backing pressure across the disc face, supporting controlled material removal on flat and contoured surfaces. Rated to a maximum of 13,000 RPM, the 56180 is suited for production grinding, finishing, and surface prep work in metal fabrication, woodworking, automotive body, and general industrial applications. Installation and pad changes are handled by grinding and finishing tradespeople, maintenance technicians, and experienced fabricators.

The DYNABRADE 56180 is intended for use with random orbital sanders that accept a 5/16-24 threaded spindle. The medium grade backing density makes it appropriate for applications requiring moderate compliance between the pad and workpiece, including flush sanding, light stock removal, and surface conditioning. It is compatible with hook and loop abrasive discs, allowing for fast disc changes without adhesives. Typical use environments include automotive refinishing shops, metal fabrication facilities, woodworking operations, and general maintenance settings where a reliable threaded backing pad is required.

Key Features

• Hook and loop interface for fast, tool-free abrasive disc changes
• 5/16-24 male threaded mount for secure spindle attachment on compatible random orbital sanders
• Medium grade density delivers consistent backing pressure for controlled surface contact

Compatibility

Designed as a threaded replacement backing pad for random orbital sanders equipped with a 5/16-24 male threaded spindle interface.

Installation Notes

Installation is performed by threading the pad directly onto the sander spindle by hand until fully seated. Always power down and disconnect the sander from its air supply or electrical source before removing or installing a backing pad. Inspect the spindle threads for wear or damage before installation. Do not exceed the rated maximum RPM of 13,000 during operation.
