Diablo’s new SandNet discs with reusable sanding technology are the most advanced sanding discs on the market with 10x longer life versus standard sanding discs. SandNet discs 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.
