Royal diamond brushes can be used on existing tools that are used every day in fabrications shops. The Royal Frankfurt Brush removes the “softer” material in the stone to create a beautiful texture while enhancing the natural color in the stone. The Royal Frankfurt Brush comes in 36, 46, and 60 grit. Made with many narrow bristles, the Royal Frankfurt Brush removes material more aggressively and cuts deeper to create a nice antique look.
