About Grit Brush Fill Material
This Nylon filament is impregnated with silicon carbide grit particles. The two numbers designate the filament diameter and the grit particle size. The first number is the diameter and the larger the diameter, the stiffer the bristle. The second number is the particle size and, like sandpaper, the smaller the number, the more aggressive the scrubbing.
