At 9 inches in diameter, this disc carries a 180-grit aluminum oxide abrasive rated as very fine grade, making it well-suited for fine stock removal, surface prep, and pre-finishing passes. The cloth backing — rated X-weight — provides flexibility and durability under load. The PSA mount allows fast disc changes on compatible backup pads without hook-and-loop hardware. Licensed tradespeople and production grinding shops typically reach for this disc when a consistent, refined scratch pattern is needed ahead of finishing coats or polishing steps.\u003c\/p\u003e\u003cp\u003eThis disc is used in metalworking, woodworking, and general fabrication environments where a 9-inch PSA backup pad is already installed on a random orbital, disc sander, or bench grinder. The flexible cloth backing conforms to slightly contoured workpieces, reducing the risk of uneven cut patterns. The 180-grit aluminum oxide abrasive is appropriate for smoothing welds, removing light surface oxidation, leveling wood grain, or blending body filler in light fabrication work. No vacuum holes are included, so this disc is suited for non-dust-extraction setups or where the backup pad itself does not require hole alignment.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e9-inch diameter PSA disc — mounts directly to adhesive-compatible backup pads\u003c\/li\u003e\n\u003cli\u003e180-grit aluminum oxide abrasive — very fine grade for finish prep and scratch refinement\u003c\/li\u003e\n\u003cli\u003eX-weight cloth backing — flexible enough for mild contours, durable under sustained contact pressure\u003c\/li\u003e\n\u003cli\u003eNo vacuum holes — simplified setup on non-extraction disc sanders\u003c\/li\u003e\n\u003cli\u003eSeries R228 construction — consistent grit distribution across the disc face\u003c\/li\u003e\n\u003cli\u003eBrown disc color aids visual inspection of wear during use\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with 9-inch PSA (pressure-sensitive adhesive) backup pads on disc sanders, random orbital machines, and similar rotary finishing equipment.

Power down and unplug or de-energize the sander before removing or applying the disc. Clean the backup pad surface of debris and adhesive residue before applying the new disc to ensure full contact and proper adhesion. Do not exceed the RPM rating of the backup pad or sander when using PSA discs.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDisc Diameter\u003c\/strong\u003e: 9 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 180\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Aluminum Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Very Fine\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\u003eAttachment Type\u003c\/strong\u003e: PSA (Pressure-Sensitive Adhesive)\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\u003eDisc Color\u003c\/strong\u003e: Brown\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: R228\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0016 pounds\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: 66261109697\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51542083764530,"sku":"66261109697","price":904.42,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/05e8bff61946c20c2b6eb3253d60d650.jpg?v=1785891561","url":"https:\/\/voomisupply.com\/products\/norton-66261109697-psa-disc-9-in-180-grit-aluminum-oxide","provider":"Voomi Supply","version":"1.0","type":"link"}
