Mirka Hiolit XO is a durable, semi-open stiff abrasive designed for belt sanding and other machine sanding applications, offering excellent edge wear resistance. It delivers high-quality results, especially on challenging materials. The coarser grits (36 to 80) are made on a sturdy polyester cloth, while the finer grits (100 to 240) use a more flexible X-weight cotton cloth for enhanced adaptability.
