Up to 4x faster than standard fibre discGrinding down welds on fabricated stainless steel workpieces is tough and time-consuming. If the process can be speeded-up, there is a significant efficiency gain for the skilled craftsmen who do this job. And with the Expert R782 Prisma Ceramic Fibre Disc you can grind much, much faster.Bosch Prisma Ceramic offers a grain of perfectly sharp triangles which cut more effectively than even standard ceramic grains. This highly efficient disc generates less surface heat as you work, allowing you to grind faster, for longer. Additionally, a self-sharpening effect ensures this speed advantage is maintained over a long lifetime.The Bosch Expert R782 Prisma Ceramic Fibre Disc for Inox allows you to grind stainless steel much faster than conventional discs, with no compromise on quality. It therefore offers a leap forward in productivity for professionals using angle grinders.With 22.23 mm bore for standard locking nut angle grinders.Cool Grinding• The cooling aids in the top coat of the fibre disc help displace heat during the grinding process, allowing you to grind faster, for longer.No Deformation• Cambered design means the discs do not curl. They therefore have an excellent fit to the backing pad, to deliver the best working results.Self-Sharpening• Stays faster for longer due to self -sharpening effect.
