Merit Abrasives 08834174103 Psa Disc Backing Pad

Product Description

The MERIT ABRASIVES 08834174103 is a PSA adhesive disc backing pad designed to mount pressure-sensitive adhesive sanding discs for rotary grinding and finishing applications. The pad accepts a 0.25 inch shank for use with standard die grinders and rotary tools and is rated to a maximum speed of 3,500 RPM. It provides a stable, secure mounting surface that keeps PSA discs firmly seated during material removal, blending, and surface prep work. This type of backing pad is a routine consumable tool component used by metalworkers, fabricators, and finishing technicians across production and maintenance environments.

This backing pad is suited for use with PSA sanding discs in grinding, deburring, and surface conditioning tasks on metal, wood, and composite materials. It is appropriate for both shop and field use where a die grinder or rotary tool with a 0.25 inch collet is the driving tool. Typical applications include weld blending, rust removal, and surface preparation ahead of coating or inspection.

Installation Notes

Installation is performed by threading the 0.25 inch shank into a properly sized collet on a die grinder or compatible rotary tool.
