Backing Pad 3M 115×22 mm M14 Hook-and-Loop for Scotch-Brite

Backing Pad 3M 115×22 mm M14 Hook-and-Loop for Scotch-Brite is a support accessory engineered to hold Scotch-Brite discs on rotary tools and angle grinders. The pad measures 115 mm in diameter with a 22 mm thick face, and it uses an M14 threaded arbor for screw-on mounting. Hook-and-loop fastening secures abrasive or conditioning discs for rapid installation and removal, ensuring stable contact between the disc and the work surface when performing grinding, surface conditioning, or finishing operations on metal and other substrates.

Advantages

The backing pad provides reliable disc retention through its hook-and-loop surface and a standard M14 threaded connection compatible with many grinders. Its construction maintains consistent contact pressure across the disc to improve finish uniformity and reduce vibration. The pad’s dimensions are suited to a wide range of Scotch-Brite disc sizes, enabling quick disc changes and minimizing downtime. Designed for mechanical durability, it supports repeated use in workshop and industrial environments.

How to use

Ensure the tool is disconnected from power before mounting the backing pad. Screw the M14 threaded arbor of the pad onto the grinder spindle and tighten securely according to the tool manufacturer’s torque recommendations. Align a hook-and-loop Scotch-Brite disc onto the pad surface, pressing firmly to achieve full contact. Operate the tool at the recommended speed for the chosen disc and material, applying even pressure and keeping the disc flat against the workpiece to avoid uneven wear. After use, remove the disc by peeling it from the pad and store both pad and discs clean and dry.

Recommendations

Use appropriate personal protective equipment such as eye protection, gloves, and hearing protection. Match the disc type and grit/grade to the material and task for optimal results, and follow the maximum safe speed ratings of both the disc and the backing pad. Inspect the pad regularly for wear, deformation, or damage and replace it if any structural compromise is detected.
