Diablo's Reusable Hand Sanding Block maximizes sanding performance by enabling professional users to sand flat and contour surfaces with one tool. This premium, angled foam tool includes two sides: cushioned for controlled material removal in contour sanding, and dense for aggressive material removal on flat surfaces. Hook Lock™ backing allows repeated attachment and removal of Diablo SandNET™ sheets. Included with the reusable hand sanding block are five SandNET™ sheets, ranging from coarse/removal to ultra-fine finish. The reusable SandNET™ nylon design is easy to clean and reuse multiple times, simply shake, vacuum or rinse to remove any build up.
