Merit Abrasives 08834167074 Quick-change Disc 3 in 50 Grit

Product Description

The MERIT ABRASIVES 08834167074 is a 3-inch coated quick-change abrasive disc built for aggressive stock removal on metal and wood surfaces. It uses a zirconia alumina abrasive grain, which is self-sharpening and maintains cutting efficiency throughout the disc life. The 50-grit coarse grade makes it well-suited for weld blending, deburring, and rapid material removal. Backed by a Y-weight polyester cloth with a waterproof construction, this disc handles demanding grind cycles without premature breakdown. It attaches via a Type S Power-Lock system compatible with TS Type II quick-change holders, and is rated to 20,000 RPM for safe use on handheld disc sanders. Licensed tradespeople and fabricators in metal finishing and woodworking shops rely on this format for repeatable, fast disc swaps.

This disc is designed for use with handheld disc sanders equipped with a TS Type II quick-change attaching system. Its semi-open coat minimizes loading, making it effective across a range of materials including 300 and 400 Series stainless steel, aluminum, brass, bronze, hard and soft carbon steels, and hard and soft woods. It is well-suited for both fabrication shops and field service environments where frequent disc changes and consistent cut rates are required. The disc is flexible, which allows it to conform to contoured or irregular surfaces without sacrificing abrasive contact.
