Grinding Metal and Stainless Steel
with Bosch Prisma Technology
The performance of the Bosch EXPERT Prisma Ceramic has been tested against quality products in a Bosch lab: the EXPERT R782 Prisma Discs grind stainless steel up to 4X faster than our standard R444 Fibre Discs.
There is a significant efficiency gain for the skilled craftsmen who do this job.
The special structure of Bosch Prisma Ceramic ensures grains sharpen themselves as they work.
The optimal triangular shape of every single ceramic grain offers a far more consistent cutting action than traditional abrasive grits, delivering not only high-speed metal grinding but also an excellent finish and increased product life.
The special structure of Bosch Prisma Ceramic ensures grains sharpen themselves as they work, making working with them even more productive.
When you do eventually need to change a disc, this can be fast too – thanks to X-LOCK, Bosch’s fast angle grinder accessory changing system.
Additionally, the cambered design of the EXPERT R781 and R782 means the metal grinding discs are not deformed in use. By keeping their ideal flat shape, these EXPERT grinding discs maintain their fit with the backing pad for best working results.
