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