Merit Abrasives 69957399611 Quick-change Disc 240 Grit

Product Description

The MERIT ABRASIVES 69957399611 is a quick-change abrasive disc designed for use with Power-Lock Type S attaching systems. It measures 3/4 inches in diameter and features a 240-grit aluminum oxide abrasive surface, placing it in the very fine grade range. The disc carries a rigid polyester backing with a Y-weight designation and is rated for a maximum of 40,000 RPM. It ships individually but is sold in minimum order quantities of 100 units. Licensed abrasive tool operators and metalworking trades use this disc for fine surface finishing, deburring, and light material removal in confined or detail work areas.

This disc is suited for fine finishing passes on metal surfaces in both shop and field environments. The small 3/4-inch diameter makes it appropriate for tight corners, tube ends, weld seams, and other areas where a larger disc cannot reach. The aluminum oxide abrasive and rigid backing hold up under consistent rotational load, making it a reliable choice for repetitive production finishing work or prep work ahead of coating or inspection.
