Dynabrade 56320 Disc Backing Pad Hook Loop 5/16-24

Product Description

The DYNABRADE 56320 is a hook and loop disc backing pad designed for use with random orbital sanders. It accepts standard 5/16-24 male threaded spindles and is rated to a maximum of 13,000 RPM. The medium-density construction provides consistent pad contact across the work surface, supporting uniform material removal. Forty-four vacuum holes are integrated into the pad face, enabling dust extraction when paired with a compatible vacuum system. Licensed abrasive technicians and finishing contractors rely on this type of backing pad for surface prep, paint removal, and finish-sanding operations across metal, wood, and composite substrates.

This backing pad is suited for light industrial and professional finishing applications where a threaded-mount hook and loop system is required. It installs on random orbital sanders with a 5/16-24 threaded spindle. The medium grade is appropriate for general-purpose material removal and blending work. The 44-hole vacuum pattern supports dust-controlled environments such as auto body shops, cabinet shops, and clean finishing booths where airborne particulate must be managed.

Compatibility

Designed as an OEM-style threaded backing pad replacement for random orbital sanders that accept a 5/16-24 male threaded spindle and hook and loop abrasive discs.

Installation Notes

Installation is performed by threading the pad directly onto the sander spindle by hand until snug. Power down and disconnect the sander from its air supply or electrical source before mounting or removing the backing pad. Do not exceed the 13,000 RPM maximum rated speed. Inspect the pad face and hook material for wear or damage before each use and replace if the hook retention is compromised.
