Engineered with a heavy-duty, ultra-coarse 36 grit silicon carbide matrix, this rubbing brick is built for aggressive material removal on masonry, stone, and concrete floors. The ergonomic fluted design creates channels that clear slurry and debris fast, keeping the cutting surface clean and minimising friction. Designed for exceptional durability, it stands up to the toughest manual grinding or mechanical attachment applications.

• Aggressive 36 Grit Matrix - Features coarse silicon carbide grains that rapidly grind down high spots, rough concrete, stone, and heavy masonry surfaces.
• Versatile Surface Prep - Perfect for removing concrete form marks, smoothing rough welds, erasing surface imperfections, and cleaning stubborn rust or scale.
• Long-Lasting Durability - Built with a high-density, resin-bonded carborundum compound that resists premature crumbling and extends the blocks lifespan.
• Dual-Use Application - Fits seamlessly into heavy-duty floor grinding machines or functions as a highly effective manual hand rubbing brick.
