Merit Abrasives 69957399741 Quick-change Disc 60 Grit

Product Description

The MERIT ABRASIVES 69957399741 is a Power-Lock Type 1 quick-change disc engineered for handheld disc sanders in metalworking and fabrication applications. At 3/4 inch in diameter, the disc uses 60-grit aluminum oxide abrasive on a Y-weight 2-ply polyester backing rated for a maximum of 40,000 RPM. The coated abrasive grain features a special coating designed to extend disc life and maintain a faster cut rate under moderate to demanding use. It is suited for stock removal and weld blending tasks where a medium-coarse cut profile is required. Installation and changeover use the Power-Lock (Type P) quick-change attaching system, making tool-free swaps fast on compatible grinders and handheld disc sanders.

This disc is designed for use on a broad range of metals including 300 and 400 series stainless steel, aluminum, brass, bronze, hard carbon steels, soft carbon steels, and titanium. The rigid backing provides consistent abrasive contact across the workpiece surface, making it a reliable choice for weld blending, surface prep, and material removal in production shops, field fabrication, and maintenance environments. It is compatible with handheld disc sanders accepting the Power-Lock Type P quick-change interface. This SKU is sold individually but carries a minimum order quantity of 100 units.

Installation Notes

Installation is performed by pressing the disc onto a Power-Lock mandrel until the locking mechanism engages — no tools required. Before mounting or removing the disc, ensure the grinder or sander is powered off and disconnected from its power source. Verify the tool's rated RPM meets or exceeds the disc's maximum RPM rating before use. Inspect the disc for damage or wear before each use and replace immediately if backing or abrasive shows signs of separation or cracking.
