Merit Abrasives 69957399749 Quick-change Disc 24 Grit

Product Description

The MERIT ABRASIVES 69957399749 is a quick-change abrasive disc designed for rapid material removal in grinding and surface preparation applications. Built with 24-grit aluminum oxide on a rigid polyester backing, this disc delivers aggressive, very coarse stock removal on ferrous metals, welds, and castings. The Power-Lock Type 1 attaching system allows fast disc swaps without tools, reducing downtime during high-volume work. At 1 inch in diameter and rated to 40,000 RPM, it is sized for use with compact right-angle grinders and die grinders. Licensed tradespeople and fabricators working in tight clearances rely on this disc for consistent cutting action.

This disc is suited for metal fabrication shops, maintenance and repair operations, and light manufacturing environments where rapid stock removal on small surface areas is required. The aluminum oxide abrasive and rigid polyester Y-weight backing hold up under sustained pressure, making it appropriate for weld blending, deburring, and surface conditioning on steel and other hard metals. It is sold individually with a minimum order quantity of 100 units, making it a practical stocking item for shops with ongoing abrasive demand.
