This is a firm foam sanding block with 2 different grits on either side. The firmness of the block helps apply the needed force to remove material from whatever project as fast as you need it too.
The dual grit block comes in 2 different grit combinations. Coarse/Medium and Fine/Superfine.
Similar to our High Flex Pads these blocks can not be categorized by the normal grit numbering system. The grit is applied directly to the foam and depending on how much force you use on the project, will change the amount of material removed, and the quality of the finish because of the nature of foam.
