It uses a zirconia alumina abrasive on a cloth backing, rated at a Y-weight backing for aggressive stock removal. At 36 grit, this disc falls in the very coarse grade range, making it well-suited for weld seam removal, rust stripping, and rapid material removal on ferrous and non-ferrous surfaces. It is rated for a maximum of 20,000 RPM and mounts via a Type R quick-change attaching system.\u003c\/p\u003e\u003cp\u003eThis disc is used in fabrication shops, welding operations, metal service centers, and maintenance facilities where frequent disc changes and consistent cut rates are required. The Type R mount allows tool-free disc swaps, reducing downtime on production grinding tasks. The coated blue zirconia alumina construction self-sharpens during use, maintaining cut rate over the life of the disc. Applications include weld blending, deburring, edge prep, and surface conditioning on structural steel and plate stock.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e36 grit very coarse zirconia alumina abrasive for aggressive stock removal\u003c\/li\u003e\n\u003cli\u003eType R quick-change attaching system for fast, tool-free disc changes\u003c\/li\u003e\n\u003cli\u003eCloth backing with Y-weight construction for durability under load\u003c\/li\u003e\n\u003cli\u003e20,000 RPM maximum speed rating for compatibility with standard die grinders\u003c\/li\u003e\n\u003cli\u003eSelf-sharpening zirconia alumina grain maintains cut rate through the disc life\u003c\/li\u003e\n\u003cli\u003eBlack button with blue disc color for quick visual grit identification\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with Type R quick-change disc holders and compatible die grinders and angle grinders that accept 3-inch TR-style quick-change discs.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation of quick-change abrasive discs is typically performed by grinding and fabrication professionals. Before mounting, confirm the tool spindle speed does not exceed the 20,000 RPM disc rating. Ensure the quick-change mandrel is clean and the locking mechanism is fully engaged before operating the tool. Always wear appropriate PPE including eye protection and gloves when performing grinding operations.\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\u003eGrit\u003c\/strong\u003e: 36\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Very Coarse\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Zirconia Alumina\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\u003eAttaching System\u003c\/strong\u003e: Type R (TR)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 20,000\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\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\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: 69957323758\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TRU-MAXX","offers":[{"title":"Default Title","offer_id":51742389895474,"sku":"69957323758","price":5104.28,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7d7be2a3e23a806438fa714a53951f82.jpg?v=1788837151","url":"https:\/\/voomisupply.com\/products\/tru-maxx-69957323758-quick-change-disc-36-grit-3-in-tr","provider":"Voomi Supply","version":"1.0","type":"link"}
