Bosch EXPERT R782 PRISMA Grinding disc

The Bosch EXPERT R782 PRISMA grinding disc is engineered for efficient removal of welds and fast material stock removal on stainless steel (Inox) and general steel. Featuring a flat-centre design and Prisma ceramic fibre construction, this pack of five discs delivers improved cutting speed and consistent finish while maintaining durability for professional use.

Advantages

The EXPERT R782 Prisma Ceramic Fibre Disc combines high cutting speed with long life, reducing grinding time on fabricated stainless steel workpieces. Its construction minimises heat build-up and helps preserve the workpiece quality while providing uniform grit wear. The flat-centre geometry ensures stable contact and predictable material removal, and the X-LOCK compatible design simplifies attachment to angle grinders.

Suitable for

• Grinding down welds on stainless steel (Inox)
• Fast stock removal on thin steel sheets
• Surface preparation before finishing or welding

How to use

Mount the disc on a compatible angle grinder following the tool and disc manufacturer instructions. Secure the disc with the X-LOCK attachment or appropriate flange and ensure the grinder is switched off while fitting. Operate the grinder at the recommended speed and apply even, controlled pressure to grind welds or remove material from stainless steel; avoid excessive force that can cause glazing or uneven wear. Allow the disc to cool periodically when performing extended work.

Recommendations

Use appropriate personal protective equipment (safety glasses, gloves, hearing protection and a dust mask). For best results on thin stainless steel sheets, use steady, light passes to minimise heat transfer and risk of distortion. Replace discs showing significant wear or damage and follow local waste-disposal regulations for used abrasive products.
