Using a Power-Lock Type R attaching system, it mounts and releases quickly without tools, reducing downtime during disc changes. The disc is constructed with aluminum oxide abrasive grain bonded to a rigid polyester backing, delivering consistent cut at 180 grit for very fine surface preparation. At 0.75 inches in diameter, this compact disc is designed for tight-radius work, weld seam blending, and detail grinding where larger discs cannot reach. Rated to 40,000 RPM, it is suitable for high-speed die grinders and rotary tools used in fabrication and finishing applications.\u003c\/p\u003e\u003cp\u003eThis disc is used in metalworking, fabrication shops, and maintenance environments where precise surface finishing is required in confined areas. The small 0.75-inch diameter makes it effective for deburring, light stock removal, and surface conditioning on welds, ports, and tight contours. It is typically installed and operated by machinists, pipefitters, sheet metal workers, and general fabrication technicians. The brown cloth-backed construction provides durability through repeated passes on ferrous and non-ferrous metals.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003ePower-Lock Type R attaching system for tool-free disc changes on compatible quick-change mandrels\u003c\/li\u003e\n\u003cli\u003e180 grit aluminum oxide abrasive for very fine material removal and surface finishing\u003c\/li\u003e\n\u003cli\u003eRigid polyester backing maintains disc shape and consistent contact on curved surfaces\u003c\/li\u003e\n\u003cli\u003e40,000 RPM maximum speed rating suitable for high-speed rotary and die grinder use\u003c\/li\u003e\n\u003cli\u003eCompact 0.75-inch diameter designed for restricted access, detail work, and tight-radius applications\u003c\/li\u003e\n\u003cli\u003eSeries R766 construction with brown disc color for quick visual grit identification\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with quick-change mandrels that accept the Power-Lock Type R attaching system, commonly found on die grinders and rotary tools used in fabrication and metalworking applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and operation should be performed by qualified personnel familiar with abrasive tool safety practices. Verify the tool spindle speed meets or exceeds the disc maximum RPM rating before mounting. Inspect the disc for damage before each use and ensure the quick-change mandrel is rated for the Type R attaching system. Always wear appropriate PPE including eye protection and gloves when operating rotary abrasive tools.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDisc Diameter\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Aluminum Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 180\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Very Fine\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAbrasive Type\u003c\/strong\u003e: Coated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAttaching System\u003c\/strong\u003e: Type R (Power-Lock)\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\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\u003eMaximum RPM\u003c\/strong\u003e: 40,000\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: R766\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.001 pounds\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: 100\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: 69957399678\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MERIT","offers":[{"title":"Default Title","offer_id":51561168961842,"sku":"69957399678","price":3976.24,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5b070c80bb819b1ab0f5dd629d07b025.jpg?v=1786462915","url":"https:\/\/voomisupply.com\/products\/merit-abrasives-69957399678-quick-change-disc-180-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
