150mm Velcro Backed Bona Black 8100 Silicon Carbide sanding discs, a high quality abrasive made of silicon carbide, also known as carborundum, a very hard mineral that creates new sharp points when worn. It works best as a “finishing” abrasive that provides the best colour when staining and oiling.
The high-quality silicon-carbide abrasive grains continually break-down into fine cutting points, giving you the best surface quality for natural, stained and oiled wood floors. Ensuring maintained aggressiveness during its lifetime, its properties ensure cool running on high speed machines such as edge sanders and the Bona flexi sand.
