Part of the 3M 6234J series, it features a diamond abrasive at 800 grit (Grade M20) bonded to a flexible polyester (J-weight) backing. The disc measures 2 inches in diameter and attaches via the Roloc TR Type R system, allowing fast, tool-free disc changes on compatible right-angle grinders and die grinders. It is rated to a maximum of 25,000 RPM and weighs 0.16 pounds. The disc color is brown with a white center button. Installations are typically performed by machinists, tool and die technicians, fabricators, and maintenance professionals who require fine finishing passes on hard or abrasion-resistant surfaces.\u003c\/p\u003e\n\u003cp\u003eThis disc is suited for fine finishing and polishing operations on hard materials including ceramics, glass, carbide, stone, and hardened metals where conventional aluminum oxide or zirconia abrasives are insufficient. The 800-grit diamond abrasive delivers controlled material removal at fine finish stages, making it appropriate for bench grinder work, handheld die grinder applications, and surface prep in tight or contoured areas. The 2-inch diameter makes it particularly effective in confined workspaces where larger discs cannot reach.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e800-grit diamond abrasive for fine finishing on hard and abrasion-resistant materials\u003c\/li\u003e\n  \u003cli\u003eRoloc TR (Type R) attachment system enables fast, one-handed disc changes\u003c\/li\u003e\n  \u003cli\u003eFlexible J-weight polyester backing conforms to contoured surfaces\u003c\/li\u003e\n  \u003cli\u003eRated to 25,000 RPM for use with standard die grinders and right-angle grinders\u003c\/li\u003e\n  \u003cli\u003eCompact 2-inch diameter for access in confined or detailed work areas\u003c\/li\u003e\n  \u003cli\u003e3M 6234J series construction for consistent grit distribution and cut performance\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with Roloc TR (Type R) compatible right-angle grinders and die grinders that accept 2-inch quick-change discs.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by qualified personnel familiar with abrasive tooling and grinder operation. Ensure the grinder is fully powered down and disconnected from its power source before mounting or removing the disc. Verify that the tool's rated RPM meets or exceeds the disc maximum of 25,000 RPM before operation. Always inspect the disc for damage before use and follow applicable ANSI B7.1 safety standards for abrasive wheel use.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDisc Diameter\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Diamond\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 800\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: M20\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: Roloc TR Type R\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: J (Flexible)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 25,000\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: White\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 6234J\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.16 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: 3M\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 7100003670\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51699131351346,"sku":"7100003670","price":44.04,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/19e6f06a0003ecb61e161660a57ce3de.jpg?v=1788372567","url":"https:\/\/voomisupply.com\/products\/3m-7100003670-quick-change-disc-800-grit-diamond-2-in","provider":"Voomi Supply","version":"1.0","type":"link"}
