At 1-1\/2 inches in diameter, it mounts to Type R and TR (Type III) quick-change tools without the need for separate hardware. The disc uses zirconia alumina abrasive at 50 grit, a coarse grade well suited for fast stock removal. A cloth backing with Y-weight construction gives it the rigidity to hold up under pressure. Maximum rated speed is 20,000 RPM. This disc is sold individually but requires a minimum order quantity of 100 units.\u003c\/p\u003e\u003cp\u003eThis disc fits grinding, blending, and weld dressing tasks in fabrication shops, maintenance environments, and field metalwork. The 1-1\/2-inch format is commonly used in tight spaces and on contoured surfaces where larger discs cannot reach. The zirconia alumina grain self-sharpens during use, which extends disc life compared to aluminum oxide alternatives. The blue cloth backing and black button are standard visual identifiers for this disc type. Licensed tradespeople in welding, pipefitting, and general metalwork are the primary users of this product.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eZirconia alumina abrasive grain for aggressive, self-sharpening cut action\u003c\/li\u003e\n\u003cli\u003e50 grit coarse grade rated for fast stock removal and weld dressing\u003c\/li\u003eType R and TR (Type III) quick-change compatibility for tool-free mounting\u003cli\u003eY-weight cloth backing provides stiffness and durability under load\u003c\/li\u003e\n\u003cli\u003eRated to 20,000 RPM for use with standard die grinders and quick-change tools\u003c\/li\u003e\n\u003cli\u003e1-1\/2-inch diameter for access in tight or contoured work areas\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with Type R and TR (Type III) quick-change mandrels and rotary tools rated for 1-1\/2-inch discs at 20,000 RPM or higher.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by trade professionals in fabrication, pipefitting, or maintenance roles. Before mounting, confirm the tool spindle speed rating meets or exceeds 20,000 RPM and accepts Type R or TR (Type III) discs. Secure the disc fully onto the mandrel button before powering the tool. Always wear appropriate eye protection and follow ANSI B11 and OSHA 29 CFR 1910.215 abrasive wheel safety guidelines during use.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDisc Diameter\u003c\/strong\u003e: 1-1\/2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Zirconia Alumina\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 50\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Coarse\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAbrasive Type\u003c\/strong\u003e: Coated\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: Y\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDisc Color\u003c\/strong\u003e: Blue\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eButton Color\u003c\/strong\u003e: Black\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQuick-Change Compatibility\u003c\/strong\u003e: Type R\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAttaching System\u003c\/strong\u003e: TR (Type III)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 20,000\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 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\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: TRU-MAXX\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 69957323748\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TRU-MAXX","offers":[{"title":"Default Title","offer_id":51742384914738,"sku":"69957323748","price":4991.65,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b8395b226fca8fe9a0452845f4bea9bb.jpg?v=1788837116","url":"https:\/\/voomisupply.com\/products\/tru-maxx-69957323748-quick-change-disc-1-1-2-in-50-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
