Merit Abrasives 69957399647 Quick-change Disc 240 Grit 2in

Product Description

The MERIT ABRASIVES 69957399647 is a 2-inch coated quick-change abrasive disc designed for use with Power-Lock Type S attachment systems on handheld disc sanders. Built on a rigid, X-weight 2-ply polyester backing, this disc runs at up to 30,000 RPM and delivers a fast cut rate with extended service life. At 240 grit, it falls in the very fine grade range, making it well suited for precision deburring, surface cleaning, and detail finishing work where surface finish quality matters. The aluminum oxide abrasive grain and durable polyester cloth backing are engineered to hold up under sustained use on tough materials.

This disc is intended for use on ferrous and non-ferrous metals in fabrication, welding, and finishing environments. Rated material applications include 300 Series stainless steel, brass, bronze, hard carbon steels, soft carbon steels, and titanium. It is sized for compact handheld disc sanders and fits workflows where a small-diameter disc is required for tight access or detail work. These discs are typically used by metal fabricators, maintenance technicians, and machinists working on structural components, pipe, and sheet metal assemblies.

Installation Notes

Inspect the disc for damage before each use and confirm the backing pad is compatible with a Type S quick-change attachment system. Verify the tool spindle speed does not exceed the 30,000 RPM maximum disc rating before operating. Power down and disconnect the sander from its power source before mounting or removing the disc. Eye and face protection, as well as appropriate respiratory protection, should be worn during all grinding and finishing operations.
