Grinding disc Bosch EXPERT R782 PRISMA

The Bosch EXPERT R782 PRISMA grinding disc is engineered for fast, efficient removal of welds and material on stainless steel and steel sheet workpieces. Designed for flat-centre angle grinder applications and supplied in packs of five, this X-LOCK Prisma Ceramic Fibre Disc combines speed with durable abrasive performance to support professional metalworkers who need reliable, repeatable results.

Advantages

The EXPERT R782 Prisma Ceramic Fibre Disc delivers significantly higher material removal rates on Inox compared with conventional discs while maintaining a consistent finish. Its ceramic-based fibre construction improves disc life and cutting speed, and the X-LOCK mounting system ensures quick, tool-free fitting and secure attachment during operation.

Suitable for

• Grinding down weld seams on stainless steel (Inox)

How to use

Fit the disc to a compatible angle grinder with X-LOCK interface following the grinder manufacturer’s safety instructions. Start grinding using moderate pressure and consistent motion across the stainless surface to remove welds and blend edges. Allow the disc to do the cutting—avoid excessive force that can reduce disc life and increase heat build-up. Replace discs when abrasive performance or surface finish declines.

Usage recommendations

For optimal results on stainless steel, use appropriate personal protective equipment, control grinder speed within the tool’s recommended range, and perform intermittent passes to limit heat transfer to the workpiece. Store discs in a dry environment and use within recommended shelf life.
