3M 7100070424 Disc Backing Pad Quick-change Type P

Product Description

The 3M 7100070424 is a hard-density disc backing pad designed for Quick-Change Type P disc attachment systems. It accepts 1/4-20 female thread mounting and is rated to a maximum of 25,000 RPM, making it suitable for high-speed grinding, blending, and surface preparation tasks. The hard backing density provides firm, consistent support behind the abrasive disc, which helps maintain flat contact on metal and other rigid substrates. This pad is used by fabricators, welders, and maintenance technicians who work with Roloc TP compatible quick-change disc systems. Installation and disc swaps require no tools, reducing downtime during grinding operations.

This backing pad is used in metalworking, fabrication, and general industrial surface preparation applications. It is compatible with Roloc TP quick-change discs and attaches to die grinders and right-angle grinders equipped with a 1/4-20 threaded spindle. The hard density backing makes it well suited for flat or near-flat work surfaces where firm abrasive contact is required. It is commonly found in automotive body shops, metal fabrication shops, MRO environments, and manufacturing facilities where quick disc changes and repeatable surface finish work are priorities.
