Merit Abrasives 69957399607 Quick-change Disc 100 Grit

Product Description

The MERIT ABRASIVES 69957399607 is a quick-change coated abrasive disc engineered for use with Power-Lock Type S attachment systems. Measuring 3/4 inches in diameter, this disc uses aluminum oxide abrasive on a rigid polyester backing and runs at up to 40,000 RPM. Rated at 100 grit, it falls in the fine grade range, making it well suited for surface finishing, light stock removal, and deburring on metal, plastic, and composite substrates. Fabricators, welders, pipefitters, and general metalworkers will find this disc appropriate for tight-access grinding and blending tasks where a small-diameter disc is required.

This disc is designed for use in die grinders and other rotary tools equipped with a Type S quick-change arbor. Its small 3/4-inch diameter makes it practical for internal surfaces, pipe ends, weld seams in confined spaces, and detail work on fabricated assemblies. The coated construction delivers consistent abrasive action across the disc face. This product is sold individually with a minimum order quantity of 100 units, making it a standard bench-stock item for shops with ongoing grinding and finishing operations.
