Built on an X-weight cloth backing, the disc delivers the rigidity and durability needed for aggressive stock removal on metal, wood, and composite surfaces. The abrasive grain is aluminum oxide at 80 grit, a medium-grade cut suited to blending welds, leveling surfaces, and removing mill scale or old coatings. The flexible construction allows the disc to conform slightly to irregular work surfaces without sacrificing cutting speed. At 0.3 pounds, it is lightweight and easy to handle during disc changes.\u003c\/p\u003e\u003cp\u003eThis disc is intended for use on large-format PSA-compatible disc sanders and floor grinding equipment found in metal fabrication shops, woodworking facilities, and industrial maintenance environments. The 18-inch diameter makes it a fit for heavy-duty stationary or semi-portable grinders used in production or floor-preparation workflows. It is installed and serviced by metalworkers, fabricators, millwrights, and finishing trades professionals. The R228 series designation identifies its position within the NORTON coated abrasives line.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e18-inch diameter PSA mounting — adheres directly to compatible foam or steel backup pads without fasteners\u003c\/li\u003e\n\u003cli\u003e80-grit aluminum oxide grain provides medium-grade cutting action for stock removal and surface blending\u003c\/li\u003e\n\u003cli\u003eX-weight cloth backing resists tearing under aggressive pressure and lateral stress\u003c\/li\u003e\n\u003cli\u003eFlexible construction allows conforming contact on slightly contoured or uneven surfaces\u003c\/li\u003e\n\u003cli\u003eNo vacuum holes — suited for solid backup pads on non-dust-extraction setups\u003c\/li\u003e\n\u003cli\u003eBrown disc color consistent with NORTON R228 series coated abrasive products\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with PSA-style backup pads on large-format disc sanders and grinders that accept 18-inch abrasive discs.

Ensure the sander or grinder is powered off and disconnected from its power source before changing discs. Confirm the backup pad diameter matches the disc diameter to prevent uneven wear or edge lifting during operation. Worn or contaminated backup pad surfaces reduce adhesion and should be cleaned or replaced before mounting a new disc.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDisc Diameter\u003c\/strong\u003e: 18 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 80\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Medium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Aluminum Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBacking Material\u003c\/strong\u003e: Cloth\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBacking Weight\u003c\/strong\u003e: X\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDisc Color\u003c\/strong\u003e: Brown\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVacuum Holes\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlexible\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: R228\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.3 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: NORTON\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 66261136723\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51541715550514,"sku":"66261136723","price":36.02,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c7122d74ce837479ff613762d1d52552.jpg?v=1785882856","url":"https:\/\/voomisupply.com\/products\/norton-66261136723-psa-disc-18-in-80-grit-aluminum-oxide","provider":"Voomi Supply","version":"1.0","type":"link"}
