Bosch EXPERT R781 Prisma Ceramic Fibre Disc 180mm

The Bosch EXPERT R781 Prisma Ceramic Fibre Disc is built for professionals who need to grind down welds on fabricated metal quickly. Using Bosch Prisma Ceramic technology, it grinds up to 4x faster than the Bosch R444 Fibre Disc, giving skilled tradespeople a real efficiency gain on demanding jobs.

The grain is made up of perfectly sharp triangles that cut more effectively than standard ceramic grains while generating less surface heat. A self-sharpening effect maintains this speed advantage over a long working life, with no compromise on quality.

Designed for use with angle grinders, the cambered disc resists curling for an excellent fit to the backing pad. Available in a choice of grits and supplied in multi-packs, so you can match the disc to the stage of your metalwork.
