Built on an X-weight cloth backing, the disc delivers firm support and flexibility, making it well suited to both flat and contoured surfaces. The 80-grit aluminum oxide abrasive mineral provides consistent, moderate stock removal across a range of substrates. The PSA mount allows fast disc changes on compatible backup pads without tools. Licensed tradespeople and skilled finishers install and use this disc in production and maintenance environments.\u003c\/p\u003e\u003cp\u003eThis disc fits residential and light commercial applications wherever a 3-inch PSA backup pad is used. Typical scenarios include weld blending on metal fabrications, paint removal, rust abatement, and surface conditioning before coating. The R228 series cloth-backed construction handles higher contact pressure than paper-backed alternatives, making it a practical choice for metalworking benches, portable angle grinders with PSA pads, and drill-mounted applications. No vacuum holes are present, so it is not intended for dust-extraction sanding systems.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e80-grit aluminum oxide abrasive for medium-grade stock removal and surface blending\u003c\/li\u003e\n\u003cli\u003eX-weight cloth backing provides durability and flexibility on contoured workpieces\u003c\/li\u003e\n\u003cli\u003ePressure-sensitive adhesive (PSA) mount for tool-free disc changes on compatible backup pads\u003c\/li\u003e\n\u003cli\u003eNo vacuum holes — suited for solid backup pads without dust extraction ports\u003c\/li\u003e\n\u003cli\u003eBrown disc color; part of the NORTON R228 series\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with 3-inch PSA backup pads on angle grinders, drill attachments, and finishing tools that accept PSA-mount abrasive discs.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eDisconnect or de-energize the tool before mounting or removing the disc. Align the disc concentrically on a clean, dry PSA backup pad and press firmly from center outward to ensure full adhesive contact.
