Measuring 3\/4 inch in diameter, this disc features 36-grit aluminum oxide abrasive on a rigid polyester backing, rated for a maximum of 40,000 RPM. The coated aluminum oxide construction delivers aggressive stock removal on metal, weld seams, and surface preparation tasks. The brown disc color and black button are characteristic of the R766 series. At 0.01 pounds, this is a single-piece consumable intended for high-volume use in fabrication, maintenance, and finishing operations.\u003c\/p\u003e\u003cp\u003eThis disc is suited for metalworking applications where rapid disc changes and consistent cut rate are required. The Type R quick-change attachment system allows tool-free swaps on compatible grinders and die tools, making it practical for production environments, MRO shops, and field repair work. The very coarse 36-grit rating makes it appropriate for aggressive grinding, weld blending, and deburring on steel and other ferrous metals. Minimum order quantity is 300 pieces, making this a shop-supply or stocking purchase rather than a single-unit replacement.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eType R Power-Lock quick-change attachment for tool-free disc swaps\u003c\/li\u003e\n\u003cli\u003e36-grit aluminum oxide abrasive for very coarse, aggressive stock removal\u003c\/li\u003e\n\u003cli\u003eRigid polyester backing provides consistent cut and disc stability at speed\u003c\/li\u003e\n\u003cli\u003eRated to 40,000 RPM for compatibility with high-speed die grinders\u003c\/li\u003e\n\u003cli\u003eCoated abrasive construction on 3\/4 inch diameter disc for tight-access grinding\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with Type R Power-Lock quick-change mandrels and compatible rotary tools and die grinders that accept 3\/4 inch quick-change discs.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by a machinist, fabricator, or maintenance technician using a compatible Type R mandrel. Always confirm the tool spindle speed does not exceed the disc maximum RPM rating of 40,000 before operation. Power down and disconnect the tool from its power source before mounting or removing the disc. Inspect the disc for damage before each use and do not use damaged or delaminated discs.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDisc Diameter\u003c\/strong\u003e: 3\/4 inch\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: Aluminum Oxide\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: Polyester\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBacking Weight\u003c\/strong\u003e: Y\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlexibility\u003c\/strong\u003e: Rigid\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAttaching System\u003c\/strong\u003e: Type R\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 40,000\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\u003eSeries\u003c\/strong\u003e: R766\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 300\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: MERIT ABRASIVES\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 69957399670\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MERIT","offers":[{"title":"Default Title","offer_id":51558439551282,"sku":"69957399670","price":17450.8,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/73f1153a773558408609b868d5dc9b18.jpg?v=1786412376","url":"https:\/\/voomisupply.com\/products\/merit-abrasives-69957399670-quick-change-disc-36-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
