Bosch EXPERT R781 Depressed Centre Grinding Disc 125 mm x 6 mm, 22.23 mm Bore, Zirconia Alumina, 6-Pack 2608902404

For professionals who demand aggressive stock removal and long service life on metal and stainless steel, the Bosch EXPERT R781 grinding disc stands apart through its zirconia alumina abrasive and reinforced depressed centre design. Unlike standard aluminium oxide wheels that glaze and wear quickly, this disc maintains a sharp, consistent cut from the first pass to the last, making it the go-to choice for weld seam removal, deburring, and heavy grinding on angle grinders.

Highlights

• Zirconia alumina grain for exceptional durability and fast material removal on metal and Inox
• Depressed centre (Type 27) profile allows flush grinding and easy access to corners
• 6.0 mm thickness provides ideal balance between aggression and control
• 22.23 mm bore fits most 125 mm angle grinders without adapters
• Rated for 12,250 RPM and 80 m/s peripheral speed for high-performance tools
• Complies with EN 12413 safety standard for bonded abrasives
• Pack of 6 discs ensures you always have a fresh wheel on hand

In daily use

On the job site or in the workshop, the R781 excels at removing weld beads, smoothing rough edges, and shaping stainless steel without excessive heat build-up. The resin bonding and zirconia alumina grit resist loading, so you spend less time dressing the wheel and more time grinding. The depressed centre lets you work at a shallow angle for better control and a smoother finish, while the 6 mm thickness reduces vibration and chatter compared to thinner discs. Whether you are preparing surfaces for welding or cleaning up after fabrication, this disc delivers consistent results with minimal downtime.
