Particularly useful on sanding belts, drums and discs, a crepe block can triple the life of your sandpaper.
When your sandpaper is loaded, hold the block against the sleeve, belt or disc to strip out accumulated dust and fiber.
The small block is about 1-3/8" x 1-3/8" x 6" long. It is convenient for cleaning small surfaces, such as miniature sanding drums, and for removing packed shavings from a drill bit.
The large, 1 lb block (1-3/4" x 1-3/4" x 8") will last for years in normal use.
