Their small size also allows them to do detail work more effectively than a larger grinder. These 2 Inch zirconia quick change sanding discs with grinding aid are constructed with premium closed coat zirconia grains which fracture throughout use, continually producing a sharp point to deliver a faster cut-rate than aluminum oxide varieties. The zirconia alumina abrasive grains are resin over resin bonded which makes the abrasive moisture-resistant, harder, less flexible, heat-resistant and has superior grain retention then other bonding methods. Additionally, these 2” zirconia quick change sanding discs come equip with an active grinding aid which prevents loading, and reduces heat buildup, which not only protects the work piece from staining or burning but keeps the disc sharper for longer. These discs are built on a heavy-duty, y-weight, polyester backing with the versatile, plastic, Type R (Type III) male roll-on, roll-off attachment system. These discs must be attached to a 2-inch backing pad and are designed to be used on power drills, die grinders or air grinding tools that accept ¼” shanks. Zirconia plus grinding aid quick change discs are commonly used in the auto collision repair industry, and by metal fabricators and welders, or really anyone working with metal. These 2 inch sanding discs with grinding aid are extremely effective on carbon steel, cast iron, titanium, aluminum, brass, bronze, copper or hard woods and can also be used on heat sensitive materials such as stainless steel, nickel alloys and cobalt alloys.

They cost a bit more but seem to last a bit longer than some others I've bought on Amazon. I use them mostly on steel so that's important to me. They are also flatter.

They didn't last as long as the brand name or wurth ones but did the job.

Semble correct je ne l'ai pas encore essayé vraiment a savoir s'ils sont durables ou si c'est des cochonneries chinoise 😉.
