A disc with a diameter of 355 mm has a landing diameter of 25.4 mm, a disc thickness of 4 mm, a disc has 3 layers of fiberglass mesh. Thanks to unique technologies that allow higher maximum speeds (max. rpm 5400, max. working speed 100 m/s), the blade is ideal for cutting railroad rail and other difficult metal parts. At the same time, wear resistance and resistance to lateral loads are maintained. This drive has high performance and long service life. For machine tools and cutting machines.
