Merit Abrasives 08834168539 Disc Backing Pad Type S

Product Description

The MERIT ABRASIVES 08834168539 is a Quick-Change Type S disc backing pad designed to hold quick-change abrasive discs during grinding, blending, and finishing operations. Featuring a 0.25 inch shank diameter, this backing pad mounts directly into standard die grinders and rotary tools. It is rated to a maximum of 30,000 RPM, making it suitable for high-speed surface preparation work. The pad accepts Power-Lock Type 3 quick-change discs, allowing for fast disc swaps without tools. Trades such as sheet metal fabricators, pipefitters, and maintenance mechanics rely on this type of backing pad for weld blending, rust removal, and surface conditioning.

This backing pad is well suited to applications in light industrial, commercial, and mechanical service environments where quick-change abrasive disc systems are already in use. Typical use cases include weld seam blending on metal pipe and structural steel, paint and coating removal, and general surface prep ahead of welding or inspection. The Power-Lock Type 3 compatibility makes it a direct fit for existing quick-change disc inventory on the job site.

Installation Notes

Installation is performed by trades such as sheet metal workers, pipefitters, and general maintenance mechanics. Before mounting or removing the backing pad, power down the tool and disconnect it from its power source or air supply. Thread the shank securely into the tool collet using the appropriate wrench and confirm the collet is tightened before operation. Always verify that the abrasive disc RPM rating meets or exceeds the tool RPM before use, and inspect the pad for wear or damage before each session.
