This grey/black hand-held sanding block has an ergonomic shape with a low profile. Its performance is excellent in combination with Mirka’s mesh sanding strips. The hand-held grinding block has optimized hardness of the backing material. The hand block is designed for general use and is suitable for the needs of ART body shops. Mirka® manual sanding blocks are specifically designed for manual sanding in conjunction with Mirka’s revolutionary mesh sanding products, although they can also be used with other handle abrasives. To ensure dust-free grinding, the manual grinding block simply needs to be connected by a hose to a dust extraction system.
