Part of the 3M 6234J series, it features a diamond abrasive material at 200 grit, making it well-suited for fine finishing passes on carbide, ceramic, glass, and hardened steel. The disc uses a Type R (Roloc TR) twist-lock attachment system for fast one-handed mounting and removal on compatible angle grinders and die grinders. Backed with a flexible J-weight polyester backing, it conforms to contoured workpieces without loading. Rated to 30,000 RPM, this 1 inch disc is installed by machinists, tool-and-die techs, and maintenance mechanics.\u003c\/p\u003e\n\u003cp\u003eThis disc is appropriate for precision deburring, lapping, and surface conditioning tasks in industrial and maintenance settings. The 200 grit diamond abrasive is a standard choice when working materials that defeat conventional aluminum oxide or silicon carbide media. Its compact 1 inch diameter suits tight access areas and small-radius workpieces where larger discs cannot reach. The flexible polyester backing allows light contouring work without fracturing the abrasive layer.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDiamond abrasive material at 200 grit for fine finishing on hard and brittle materials\u003c\/li\u003e\n  \u003cli\u003eType R Roloc TR twist-lock attachment for 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 30,000 RPM for use with high-speed die grinders and angle grinders\u003c\/li\u003e\n  \u003cli\u003eCompact 1 inch disc diameter for tight-access and small-radius applications\u003c\/li\u003e\n  \u003cli\u003eSeries 6234J, Grade M74 construction for consistent abrasive performance\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with Type R (Roloc TR) quick-change disc holders and compatible angle grinders or die grinders that accept the twist-lock attachment system.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and disc changes should be performed with the grinder powered off and disconnected from its power source. Thread the Type R button into the compatible disc holder and rotate until it locks securely before powering the tool. Verify the tool spindle RPM does not exceed the 30,000 RPM disc rating before operation. Inspect the disc for damage before each use and discard any disc showing cracks, tears, or delamination.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 6234J\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: M74\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Diamond\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAbrasive Type\u003c\/strong\u003e: Coated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 200\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDisc Diameter\u003c\/strong\u003e: 1 inch\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\u003eAttachment System\u003c\/strong\u003e: Type R (Roloc TR)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 30,000\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: Red\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.3 pounds\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: 7010309472\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51693057147186,"sku":"7010309472","price":26.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d19b844aa3b84fabaeef9dd806421a0a.jpg?v=1788306741","url":"https:\/\/voomisupply.com\/products\/3m-7010309472-quick-change-disc-200-grit-diamond-1-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
