Bosch EXPERT R782 PRISMA Grinding disc

The Bosch EXPERT R782 PRISMA grinding disc is a fibre disc designed for high-speed grinding of stainless steel (Inox) and steel in flat-centre angle grinder applications. Supplied in packs of five with X-LOCK compatibility, the disc uses a Prisma ceramic grain formulation to remove welds and shape thin sheets quickly while maintaining an even finish and consistent abrasive life.

Advantages

The EXPERT R782 Prisma Ceramic Fibre Disc delivers faster material removal on stainless steel compared with conventional discs without sacrificing surface quality. Its ceramic abrasive formulation and fibre backing provide long life and stable grinding performance under demanding conditions. X-LOCK compatibility allows quick and secure disc changes on supported angle grinders.

Suitable for

• Grinding down welds on stainless steel workpieces
• Shaping and deburring thin stainless steel sheets
