Diablos SandNET sheets with reusable sanding technology are the most advanced sanding sheets on the market with up to 10x longer life versus standard coated sanding sheets. The universal net design can be used when hand sanding or with your orbital sander. Each SandNET sheet features a clog-reducing nylon net design coated in a premium ceramic blend 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 sheet to remove any pitch build-up.
