It uses Premium Ceramic Alumina abrasive on a polyester cloth backing with an X-weight rating, delivering durability and consistent cut throughout the disc life. The TR (Type III) attaching system — also referred to as Roloc TR — allows fast, tool-free disc changes on compatible right-angle die grinders and inline grinders. Rated at 25,000 RPM maximum, this disc is suited for weld blending, surface preparation, and deburring tasks common in fabrication and maintenance environments. Grit is 60, placing it in the medium grade range for stock removal without excessive surface damage.\u003c\/p\u003e\n\u003cp\u003eThis disc is used in metal fabrication shops, maintenance and repair operations, and light industrial environments. It fits applications where a small-diameter disc is needed to access tight spaces or work on smaller weld seams, pipe ends, and brackets. The ceramic alumina abrasive self-sharpens during use, making it effective on stainless steel, carbon steel, and other hard metals. It is typically installed and used by metal fabricators, pipefitters, millwrights, and maintenance technicians who require reliable, repeatable surface finishing performance.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePremium Ceramic Alumina abrasive for aggressive, self-sharpening cut on hard metals\u003c\/li\u003e\n  \u003cli\u003eTR (Type III) Roloc-style attaching system for fast, tool-free disc changes\u003c\/li\u003e\n  \u003cli\u003eX-weight polyester cloth backing for durability under heavy grinding pressure\u003c\/li\u003e\n  \u003cli\u003e25,000 RPM maximum speed rating for compatibility with standard die grinders\u003c\/li\u003e\n  \u003cli\u003e60 grit medium grade for efficient stock removal and weld blending\u003c\/li\u003e\n  \u003cli\u003eCompact 2-inch diameter for work in confined areas and on small weld zones\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with quick-change disc holders and mandrels that accept the TR (Type III) Roloc TR attaching system.

Before mounting, confirm the grinder mandrel is rated for TR (Type III) discs and that the tool free speed does not exceed the 25,000 RPM disc rating. Disconnect the air supply or unplug electric grinders before changing discs. Do not exceed the marked maximum RPM and always wear appropriate eye and face protection during operation.\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: Premium Ceramic Alumina\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: 60\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Medium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 947A\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAttaching System\u003c\/strong\u003e: TR (Type III) Roloc TR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBacking Material\u003c\/strong\u003e: Polyester Cloth\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBacking Weight\u003c\/strong\u003e: X\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: Maroon\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eButton Color\u003c\/strong\u003e: Orange\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: 0.01 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: 7100077047\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51691977638194,"sku":"7100077047","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0ea85c279ef1263a5eb90b62350cc24b.jpg?v=1788291661","url":"https:\/\/voomisupply.com\/products\/3m-7100077047-quick-change-disc-60-grit-2-inches-roloc-tr","provider":"Voomi Supply","version":"1.0","type":"link"}
