3M 7100037832 Disc Backing Pad Hook Loop 5 Inch

Product Description

The 3M 7100037832 is a hook and loop disc backing pad designed to hold abrasive discs securely during grinding, sanding, and surface preparation work. The pad measures 5 inches in diameter and accepts a 5/16-24 threaded spindle mount, making it compatible with standard right-angle grinders and disc sanders used across fabrication, mechanical, and maintenance trades. Built with a firm density backing, it maintains consistent disc contact across flat and moderately contoured surfaces. Rated to 12,000 RPM, it handles high-speed tool operation without distortion. The J-hook retention system locks discs in place and allows fast disc changes without tools.

This backing pad is suited for use in metal fabrication shops, automotive body work, HVAC equipment manufacturing, and general industrial maintenance environments. It is typically installed on pneumatic or electric right-angle grinders and random orbital sanders that accept a 5/16-24 spindle thread. The 5-inch platform accommodates the most common disc diameter used in mid-size grinding and finishing operations. Mechanics, fabricators, and maintenance technicians working with abrasive disc systems will find this pad a standard replacement component for high-cycle applications.

Key Features

• 5-inch pad diameter fits standard mid-size disc grinders and orbital sanders
• Hook and loop attachment system with J-hook design for secure disc retention and fast changeovers
• 5/16-24 threaded spindle mount for broad tool compatibility
• Firm density backing maintains flat, consistent disc contact on work surfaces
• 12,000 RPM maximum rating supports high-speed pneumatic and electric grinder use

Compatibility

Designed as an OEM-style replacement backing pad for right-angle grinders and disc sanders accepting a 5/16-24 spindle thread and 5-inch hook and loop abrasive discs.

Installation Notes

Disconnect the tool from its power or air source before removing or installing a backing pad. Thread the pad onto the spindle by hand until snug, then secure per the tool manufacturer's torque guidance using the appropriate spanner wrench. Do not exceed the 12,000 RPM maximum rating of the pad; always verify that the tool's no-load RPM does not exceed this value before operation. Inspect the hook surface for wear or contamination before attaching a new abrasive disc.
