Bona 8100 Black is a standard abrasive made of silicon carbide, also known as carborundum, a very hard mineral that creates new sharp points when worn. This ensures that it remains robust throughout its lifetime. This property – and an open coat – ensure cool running on high-speed machines, such as edge sanders.
