3M 7000045284 Disc Backing Pad 2 in Quick-change Roloc

Product Description

The 3M 7000045284 is a quick-change disc backing pad designed to mount and retain abrasive discs in grinding, blending, and finishing applications. The pad measures 2 inches in diameter and features a 1/4-20 female thread for attachment to pneumatic or electric angle grinders and die grinders. With an extra-hard density construction, it provides firm, consistent backing pressure across the disc surface. The pad is rated to a maximum of 25,000 RPM, making it suitable for high-speed tool operation. Installation and removal of compatible discs is handled through the Roloc quick-change system, reducing downtime during disc changes.

This backing pad is intended for use in metal fabrication, automotive body work, welding prep, and general surface conditioning tasks. It is commonly used by machinists, pipefitters, welders, and other trade professionals who require frequent disc changes across varying grits and types. The quick-change design allows a single pad to work with a wide range of Roloc-compatible abrasive discs without additional hardware.

Installation Notes

Installation should be performed by a qualified tradesperson familiar with abrasive tool operation and applicable ANSI safety standards for grinding equipment. Before mounting or removing the backing pad, ensure the grinder is fully powered off, disconnected from the air supply or electrical source, and the spindle has come to a complete stop. Thread the pad onto the grinder spindle by hand until firmly seated — do not use the grinder to spin the pad on. Inspect the pad for cracks or wear before each use and replace if any damage is observed.
