It uses a TR quick-change attachment system for fast, tool-free disc swaps on compatible right-angle grinders and die grinders. The ceramic abrasive grain runs at up to 30000 RPM and is bonded with a resinoid bond to a fiber backing for durability under high-pressure grinding. At 80 grit, it sits in the medium grade range, making it well suited for weld blending, surface prep, and deburring tasks common in fabrication, maintenance, and mechanical trades.\u003c\/p\u003e\n\u003cp\u003eThis disc is used in metal fabrication shops, maintenance facilities, and field repair scenarios where fast disc changes and consistent cut rates are required. It is appropriate for use on steel, stainless steel, and similar hard metals. The TR quick-change mount is a standard attachment type found on many right-angle and die grinder configurations. Licensed tradespeople in HVAC, plumbing, electrical, and general mechanical maintenance regularly use discs of this type for fitting prep, bracket work, and metal surface conditioning.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eTR quick-change attachment allows fast disc swaps without additional tools\u003c\/li\u003e\n  \u003cli\u003eCeramic abrasive grain provides aggressive cut and long disc life on hard metals\u003c\/li\u003e\n  \u003cli\u003e30000 RPM maximum speed rating supports use on standard die and angle grinders\u003c\/li\u003e\n  \u003cli\u003eResinoid bond holds abrasive grain firmly through high-pressure grinding passes\u003c\/li\u003e\n  \u003cli\u003eFiber backing resists tearing and flexing under load\u003c\/li\u003e\n  \u003cli\u003e80 grit medium grade suited for weld blending, deburring, and surface prep\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with TR quick-change grinder mandrels and right-angle or die grinders that accept 2-inch quick-change discs with a TR-style attachment.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and disc changes must be performed with the grinder powered off and unplugged or air supply disconnected. Verify the grinder spindle speed does not exceed the 30000 RPM rating of the disc before use. Eye protection, hearing protection, and appropriate gloves are required when operating abrasive discs. Inspect the disc for cracks or damage before mounting and do not use damaged discs.\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: Ceramic\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 80\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Medium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAttachment Type\u003c\/strong\u003e: TR Quick-Change\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBacking Material\u003c\/strong\u003e: Fiber\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBond Type\u003c\/strong\u003e: Resinoid\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 30000\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDisc Color\u003c\/strong\u003e: Orange\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 787C\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: 7100100962\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51701659042098,"sku":"7100100962","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/eb8efdc56366d76908450e54e47000a5.jpg?v=1788403275","url":"https:\/\/voomisupply.com\/products\/3m-7100100962-quick-change-disc-2-in-80-grit-ceramic-tr","provider":"Voomi Supply","version":"1.0","type":"link"}
