Constructed with aluminum oxide grain bonded in a non-woven fiber matrix, this coarse-grade disc removes surface contaminants, light oxidation, and weld discoloration without aggressively cutting into base metal. It mounts via the CDR Type R attaching system, allowing fast, tool-free disc swaps on compatible right-angle grinders and die grinders. Rated to a maximum of 5000 RPM, it suits common pneumatic and electric grinders used by fabricators, pipefitters, and maintenance technicians working on ferrous and non-ferrous surfaces.\u003c\/p\u003e\u003cp\u003eThis disc is suited for light to medium surface prep applications in fabrication shops, maintenance facilities, and field repair environments. Typical uses include pre-weld and post-weld blending, surface cleaning before coating or plating, and deburring on steel, stainless steel, and aluminum. The non-woven construction conforms slightly to irregular surfaces, making it useful on curved or contoured workpieces where a rigid bonded disc would leave uneven scratch patterns. It is sold and packaged as a single disc.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3-inch diameter non-woven aluminum oxide disc for surface conditioning and blending\u003c\/li\u003e\n\u003cli\u003eCoarse grade removes weld scale, oxidation, and surface contamination efficiently\u003c\/li\u003e\n\u003cli\u003eCDR Type R quick-change mount allows fast, tool-free disc changes\u003c\/li\u003e\n\u003cli\u003e5000 RPM maximum speed rating compatible with standard grinders\u003c\/li\u003e\n\u003cli\u003eNon-woven fiber matrix conforms to curved and contoured surfaces\u003c\/li\u003e\n\u003cli\u003eBrown disc color with black button; sold as single unit\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with CDR Type R quick-change systems on right-angle grinders and die grinders that accept 3-inch Type R quick-change discs.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and disc changes should be performed by a qualified operator with the grinder fully powered down and disconnected from the air supply or electrical source. Verify the grinder free-speed RPM does not exceed the 5000 RPM disc rating before mounting. Inspect the disc for damage before each use and never use a disc that shows tears, delamination, or a damaged button. Follow ANSI B7.1 and applicable shop safety standards for abrasive wheel use.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDisc Diameter\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Aluminum Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAbrasive Type\u003c\/strong\u003e: Non-Woven\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Coarse\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 5000\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQuick-Change Compatibility\u003c\/strong\u003e: CDR\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAttaching System\u003c\/strong\u003e: Type R\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDisc Color\u003c\/strong\u003e: Brown\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eButton Color\u003c\/strong\u003e: Black\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: 0.04 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31191506\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: PFERD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 42780752\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PFERD","offers":[{"title":"Default Title","offer_id":51542700720434,"sku":"42780752","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dc2f7a0f7f1019d99c35926f0e401ddb.jpg?v=1785904717","url":"https:\/\/voomisupply.com\/products\/pferd-42780752-quick-change-disc-3-in-aluminum-oxide-cdr","provider":"Voomi Supply","version":"1.0","type":"link"}
