Bosch EXPERT Prisma Ceramic X LOCK Fibre Disc 125mm

Up to 4x faster than the Bosch R444 Fibre Disc, the Bosch EXPERT R781 Prisma Ceramic X-LOCK Fibre Disc is engineered for professionals who need to grind down welds and remove stock from metal workpieces at speed, without compromising on finish quality.

At the heart of this disc is Bosch Prisma Ceramic technology — a grain of perfectly sharp triangles that cuts more effectively than even standard ceramic grains. The result is faster material removal, less surface heat build-up, and a self-sharpening effect that keeps the disc performing at its peak over a longer working life. A cambered design prevents curling, ensuring a consistent fit to the backing pad throughout use.

Compatible with both X-LOCK and nut-and-thread angle grinders, these discs are available in 36, 60, and 80 grit, in packs of 5 or 25.
