Dynabrade 50632 Disc Backing Pad 6 in 12000 Rpm

Product Description

The DYNABRADE 50632 is a rubber disc backing pad designed to mount abrasive discs on random orbital sanders used in metalworking, auto body, and general surface preparation. The pad measures 6 inches in diameter and attaches via a 5/16-24 male threaded mount, providing a secure, centered connection to compatible tool spindles. It is rated to a maximum of 12,000 RPM, making it suitable for high-speed sanding applications. The rubber construction offers flex and compliance across workpiece surfaces, helping abrasive discs conform evenly during finishing passes. This pad is a common shop consumable installed by machinists, auto body technicians, and industrial maintenance professionals.

The DYNABRADE 50632 is intended for use with random orbital sanders that accept a 5/16-24 threaded spindle. It fits typical production and maintenance sanding setups in automotive refinishing, fabrication shops, and industrial surface prep environments. The 6-inch diameter accommodates standard hook-and-loop or pressure-sensitive adhesive abrasive discs of the same size. This pad is sold individually and is a direct replacement component when an existing backing pad shows wear, glazing, or deformation that reduces abrasive contact quality.

Compatibility

Designed for use with random orbital sanders accepting a 5/16-24 male threaded spindle connection. Verify spindle thread specification on the sander before installation.

Installation Notes

Installation is typically performed by a machinist, auto body technician, or industrial maintenance professional. Power down and disconnect the sander from its air or electrical supply before removing or installing the backing pad. Thread the pad onto the spindle by hand until snug, taking care not to cross-thread the 5/16-24 connection. Do not exceed the 12,000 RPM maximum speed rating during operation.
