Merit Abrasives 69957399696 Quick-change Disc 50 Grit

Product Description

The MERIT ABRASIVES 69957399696 is a quick-change coated abrasive disc designed for use with Power-Lock Type R attachment systems on handheld disc sanders. The disc measures 1.5 inches in diameter and features 50-grit aluminum oxide abrasive, placing it in the coarse grade range. The backing is a rigid, X-weight 2-ply cloth and polyester construction that resists tearing under aggressive material removal. Licensed trades and fabrication shops use this disc for deburring, cleaning, and detailing work where a fast, repeatable disc swap is required.

This disc is suited for light to medium stock removal on a range of metals including 300 and 400 series stainless steel, aluminum, brass, bronze, titanium, and both hard and soft carbon steels. The compact 1.5-inch diameter makes it well-matched to detail work, weld cleanup, and edge prep in tight areas where a larger disc cannot reach. It is compatible with handheld disc sanders fitted with a Type R quick-change arbor. The brown disc color corresponds to the R766 series product line from Merit Abrasives.
