Bosch Abrasives for Efficient Working

EXPERT R781 Prisma for High Speed Grinding Metal

Grinding down welds on fabricated metal 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 R781 Prisma 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.

Person wearing safety equipment grinds metal, creating sparks.
