Right Angle Grinder Fiber Disc Pack, 3 Discs. High tech ceramic fibre disc with significantly more self sharpening edges due its ultra fine grit and crystal structure and a corresponding material removal rate that greatly exceeds that of conventional fibre discs. Advantage over pyramid ceramics: Despite high performance, smoother surfaces and therefore less rework on the workpiece. In addition, drive motors are significantly protected. Features: Ultra fine grit and crystal structures provide for significantly more self sharpening edges and a huge improvement in material removal. The finer grinding results on the workpiece surface reduces the frequent necessity of reworking the piece with finer grits. Even in the coarse grain range and with high material removal, the chip particle size remains relatively small, whereby damage caused by long afterglow metal particles can be prevented The universal high performance fibre disc with an especially great cooling agent content is easy on any drive motor.
