Dura-Gold Premium 240 Grit 9" Purple Ceramic Mesh Sanding Discs, Box of 10 - Dustless Hook & Loop Backing Sandpaper for Drywall Power Sander - Long-Lasting Fast Cut Abrasive, Anti-Clog Sanding Screen Unrivaled Sanding Performance: These ceramic mesh discs have a three-times longer working life than traditional abrasives. These superior-quality mesh sanding discs are manufactured with a specially treated hard ceramic grain fused with zirconia alumina. The aligned ceramic grains enable a very fast cutting speed and they deliver a super-sharp cut with a consistent scratch pattern. The tough ceramic grain wears down and fractures continuously, generating new, extra-sharp cutting edges. Dust-Free Working Environment: The discs' open mesh design allows dust particles to flow freely through thousands of uniform tiny micro holes, enabling superior sanding dust extraction, which ensures a clean, dust-free working environment and extends the life of your sanding discs. The discs have high resistance to clogging and loading, increasing productivity and reducing material consumption. Multiple Usage Applications: The extra-sharp cut and long-lasting durability of these ceramic mesh sanding discs make them suitable as the workhorse sandpaper for drywall sanding. They are ideal for use in drywall installations and also for use in autobody repair and paint shops, metalworking shops, woodworking shops, marine industry, industrial manufacturing, and much more. They sand exceptionally well on hard surfaces and are great for sanding hardwood flooring. Full Range of Sanding Grits: These premium 9" ceramic mesh sanding discs are available in variety packs with multiple grits and separately in a full range of sanding grit grades from coarse to very fine: 80, 120, 180, 220, 240, and 320.
