Part of the Wetordry 481W line, this disc uses a fast-cutting silicon carbide mineral that delivers a consistent scratch pattern without requiring heavy manual pressure. The water-resistant polyester backing allows use wet or dry, giving technicians flexibility when working on coated metals, bare metal, or hardwood substrates. It is well suited for production finishing environments where consistent surface prep results are required across repeated cycles.\u003c\/p\u003e\n\u003cp\u003eThis disc is intended for use in metal fabrication, automotive refinishing, and general surface preparation applications. It performs on a range of substrates including ferrous and non-ferrous metals and hardwoods. The 320 grit rating makes it appropriate for final-stage sanding passes before primer or topcoat application. At 5 inches in diameter, it fits standard 5-inch disc backing pads common in both shop and field environments. It can serve as an alternative to compound and lubricant-based finishing methods when a dry or water-assisted approach is preferred.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSilicon carbide mineral for fast cutting and consistent scratch pattern\u003c\/li\u003e\n  \u003cli\u003eWater-resistant polyester backing allows wet or dry operation\u003c\/li\u003e\n  \u003cli\u003e320 grit suitable for final surface prep before paint or primer\u003c\/li\u003e\n  \u003cli\u003eCompatible with a range of substrates including metals and hardwoods\u003c\/li\u003e\n  \u003cli\u003eReduces need for heavy manual pressure during finishing passes\u003c\/li\u003e\n  \u003cli\u003eCan substitute for compound and lubricant-based finishing methods\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement disc for use with standard 5-inch disc backing pads in metalworking, automotive refinishing, and general surface preparation applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eMount disc securely to a compatible 5-inch backing pad before use.
