Diablo's new Sand Net discs have the most advanced sanding technology on the market with 10X longer life versus standard sanding discs. Each Sand Net disc features a clog-reducing net design coated in premium Ceramic grit for fast material removal while reducing material build-up. The Sand Net design is easy to clean and reuse multiple times by simply shaking, vacuuming or rinsing the disc to remove any build up. The Sand Net discs includes a free application pad (a $5 value) for easy attachment to tool. Ideal for sanding wood, metal, plastic and solid surfaces.
