Product Description

The MERIT ABRASIVES 69957399752 is a 1-inch diameter quick-change coated abrasive disc designed for use with handheld disc sanders equipped with a Power-Lock Type P attaching system. Built on a rigid Y-weight 2-ply polyester backing, this disc uses premium aluminum oxide grain with a special coating that extends service life and maintains a fast cut rate on moderately demanding grinding and finishing tasks. At 50 grit, it falls in the coarse grade range, making it suited for stock removal and weld blending. Maximum operating speed is rated at 40,000 RPM. The disc is brown in color and belongs to the Series R766 product line.

This disc is intended for trade and industrial use where quick disc changes and high-speed material removal are required. It performs on a broad range of metals including 300 and 400 series stainless steel, aluminum, brass, bronze, hard carbon steels, soft carbon steels, and titanium. Typical applications include weld blending, surface prep, and stock removal in fabrication shops, maintenance environments, and field repair work performed by metalworkers and general trade contractors.
