Product Description

The MERIT ABRASIVES 69957399790 is a 3-inch coated abrasive quick-change disc designed for use with Power-Lock Type 1 (TP/Type P) handheld disc sanders. Built on a Y-weight 2-ply polyester backing, this disc delivers the rigidity needed for consistent stock removal and weld blending on moderately demanding applications. The 80-grit aluminum oxide abrasive is medium-coarse grade and features a special grain coating that extends disc life while maintaining a fast cut rate. Rated to 20,000 RPM, it is suited for metal fabrication shops, maintenance techs, and welding professionals who need reliable material removal without frequent disc changes.

This disc is engineered for use on a broad range of ferrous and non-ferrous metals. Typical applications include stock removal, surface preparation, and weld blending on structural and sheet metal components. The R766 series construction handles moderately demanding grinding tasks where a rigid, fast-cutting disc is required. It attaches via the Type P button system, compatible with standard Power-Lock quick-change disc holders.
