Bosch 2 608 621 791 angle grinder accessory Grinding disc

The Bosch EXPERT R781 fibre disc (Bosch 2 608 621 791) is designed for fast, efficient grinding of steel and stainless steel welds and fabricated metal workpieces. Supplied in a pack of 25, this Prisma Ceramic fibre disc uses Bosch’s X-LOCK system to fit angle grinders quickly and securely, delivering higher material removal rates than conventional discs while maintaining surface quality.

Advantages

The Prisma Ceramic grain provides increased cutting speed and longer life compared with standard aluminium-oxide discs. X-LOCK mounting ensures rapid disc changes without tools and a reliable connection to compatible Bosch angle grinders. The disc’s construction reduces clogging on stainless steel and helps maintain consistent grinding performance across the pack of 25 discs.

Suitable for

• Grinding down welds on steel and stainless steel
