Merit Abrasives 08834164002 Disc Backing Pad Quick-change

Product Description

The MERIT ABRASIVES 08834164002 is a quick-change disc backing pad designed to hold and drive abrasive discs in high-speed grinding and finishing applications. Built around a 0.25 inch shank and rated to 40,000 RPM maximum, this backing pad delivers consistent abrasive contact across metal, composite, and weld-prep work. It features a medium-density construction that balances rigidity and conformability, making it suitable for both flat surface work and slightly contoured geometry. It is installed and used by metal fabricators, machinists, maintenance technicians, and industrial professionals who require reliable abrasive tooling for die grinders and rotary tools.

This backing pad is intended for use with Power-Lock Type 1 compatible quick-change abrasive discs. It fits standard die grinders and rotary tools equipped with a 0.25 inch collet. The quick-change mechanism allows rapid disc swaps without additional tooling, reducing downtime during surface preparation, rust removal, weld blending, and finishing operations. It is suited to both production shop environments and field maintenance settings where speed and tool consistency are priorities.

Before installation or disc changes, ensure the tool is fully powered down and disconnected from its air or electrical source. Thread or seat the shank fully into the collet and tighten per the tool manufacturer torque guidance. Always confirm the tool RPM rating meets or exceeds the pad maximum RPM before operation, and inspect the pad and disc for damage before each use.
