Can be used wet and dry for grinding and polishing on granite, marble, concrete, composites, engineered stone, softstone and terrazzo. They are ideal for getting into 3 sided corners and difficult to access areas. Size of these triangles is 80x80x80mm. Larger triangles are available to fit Bosch machines and are also available in Telum and the Flexis Dot Pattern.
