This hand sanding block has an ergonomic shape with low profile. The performance is excellent in combination with Mirka’s net sanding strips. The hand sanding block has an optimized hardness of the backing material. Thanks to its bigger size this hand sanding block is suitable for sanding bigger and plain surfaces. Mirka® Hand Sanding Blocks are specially designed for sanding by hand in combination with Mirka’s revolutionary net-sanding products, although they can also be used with other grip abrasives. To ensure dust-free sanding the hand sanding block simply needs to be connected by hose to a dust extraction system.
