The X-LOCK fiber disc R780 Best for Metal + Inox wears material very quickly when grinding metal and Inox surfaces. The self-sharpening ceramic-grain technology creates new sharp cutting edges during grinding for a high removal rate with coarser grain and a consistent surface quality with finer grain without disc wear. The disc has a coating with coolants, making it ideal for stainless steel and structural steel. The carrier material is vulcanized fiber, which ensures stability during long work applications. This fiber disc is perfect for stripping material during welding, edge breaking, grinding, material removal, discoloring, surface treatment, decoration and finishing. X-LOCK grinding discs also fit standard angle grinders. Thanks to a keyless X-LOCK system, the fiber discs can be changed quickly and easily. The discs are suitable for clamping on an X-LOCK or standard rubber support plate. Disc diameter mm: 115, hole diameter mm: 22.23, grain size: 120, X-LOCKThis text is machine tr
