The disc measures 5 inches in diameter and uses 60-grit ceramic abrasive on a J-weight cloth backing. The ceramic abrasive grain is self-sharpening, maintaining cut rate as the disc wears. At a maximum rated speed of 12,000 RPM, this disc handles aggressive stock removal while leaving a smooth finish on a wide range of substrates. It is part of the 3M 900DZ series and weighs 0.02 pounds.\u003c\/p\u003e\n\u003cp\u003eThis disc is suited for residential and commercial shop environments as well as field fabrication work. The PSA mount makes disc changes fast on compatible 5-inch backup pads. Compatible material applications include aluminum, carbon steel, mild steel, composite, fiberglass, gelcoat, hardwood, softwood, plastic, solid surface, paint, primer, and topcoat. Typical users include metal fabricators, auto body technicians, woodworkers, and general contractors performing surface prep or finishing work. The 60-grit medium grade is well matched to stock removal, weld blending, and shaping passes before moving to finer grits.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5-inch diameter PSA mount — compatible with standard 5-inch PSA backup pads\u003c\/li\u003e\n  \u003cli\u003e60-grit ceramic abrasive grain for fast cut rate and extended disc life\u003c\/li\u003e\n  \u003cli\u003eJ-weight cloth backing provides flexibility for contoured and flat surfaces\u003c\/li\u003e\n  \u003cli\u003eRated to 12,000 RPM for use with high-speed random orbital and disc sanders\u003c\/li\u003e\n  \u003cli\u003eNo vacuum holes — designed for solid backup pads without dust extraction ports\u003c\/li\u003e\n  \u003cli\u003ePurple disc color for easy grit identification on the job\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use on aluminum, carbon steel, mild steel, composite, fiberglass, gelcoat, hardwood, softwood, plastic, solid surface, paint, primer, and topcoat.

Power down and disconnect the sander from its power source before mounting or removing the disc. Press the disc firmly and evenly onto the backup pad to ensure full adhesive contact before starting the tool. Worn or contaminated backup pads reduce adhesion and can cause disc separation — inspect the pad surface before each disc change.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDisc Diameter\u003c\/strong\u003e: 5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 60\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: Ceramic\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: J-Weight\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\u003eMaximum Speed\u003c\/strong\u003e: 12,000 RPM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVacuum Holes\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDisc Color\u003c\/strong\u003e: Purple\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 900DZ\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31191506\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: 3M\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 7100284215\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51708080324914,"sku":"7100284215","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/810c6c04c46682af90456062f313af13_b18e2173-4fcd-4a51-b9b4-f73f06d88d72.jpg?v=1788443983","url":"https:\/\/voomisupply.com\/products\/3m-7100284215-psa-disc-5-in-60-grit-ceramic","provider":"Voomi Supply","version":"1.0","type":"link"}
