The disc measures 3 inches in diameter and carries a 36-grit extra-coarse ceramic abrasive on a closed-coat YF-weight fiber backing. Ceramic abrasive grain self-sharpens during use, maintaining a consistent cut rate without loading. An additional coating reduces surface temperatures at the workpiece, making this disc well-suited for metals that are prone to heat discoloration or metallurgical change during grinding. Maximum operating speed is 20,000 RPM. Sold in a 50-pack.\u003c\/p\u003e\u003cp\u003eThis disc is used in fabrication and maintenance environments where stainless steel, nickel alloys, cobalt, Inconel, titanium, and chrome workpieces require heavy stock removal or weld blending. The TR quick-change attachment system allows fast disc swaps without tools, reducing downtime during high-volume grinding operations. The rigid fiber backing supports edge work and flat-surface grinding in both shop and field applications. Typical users include pipe fabricators, structural welders, and maintenance technicians working with exotic or corrosion-resistant alloys.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eClosed-coat ceramic abrasive covers the full disc surface for faster material removal and a smoother finish versus open-coat alternatives\u003c\/li\u003e\n\u003cli\u003eSelf-sharpening ceramic grain maintains cut rate throughout disc life\u003c\/li\u003e\n\u003cli\u003eAdditional anti-loading coating minimizes heat buildup on heat-sensitive alloys such as Inconel and titanium\u003c\/li\u003e\n\u003cli\u003eYF-weight rigid fiber backing supports aggressive cutting applications\u003c\/li\u003e\n\u003cli\u003eTR quick-change system enables tool-free disc changes at the grinder\u003c\/li\u003e\n\u003cli\u003eHeat and tear resistant construction rated to 20,000 RPM\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with TR quick-change right-angle grinders and die grinders.

Verify the grinder spindle speed does not exceed the 20,000 RPM maximum operating speed rating of the disc before use. Wear appropriate PPE including a face shield, gloves, and hearing protection during grinding operations. Inspect the disc for damage before each use and discard any disc that shows cracking, tearing, or delamination.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 1187C\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQuick-Change System\u003c\/strong\u003e: TR\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Ceramic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAbrasive Grade\u003c\/strong\u003e: Extra Coarse\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 36\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Coverage\u003c\/strong\u003e: Closed\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBacking Material\u003c\/strong\u003e: Fiber\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBacking Weight\u003c\/strong\u003e: YF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Operating Speed\u003c\/strong\u003e: 20,000 RPM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eResistance Properties\u003c\/strong\u003e: Heat, Tear\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Purple\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePack Quantity\u003c\/strong\u003e: 50\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCountry of Origin\u003c\/strong\u003e: USA (subject to change)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 7100331749\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51525291278642,"sku":"7100331749","price":219.4,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bf06d7d04b71eed9d69a05e6125f7de8_2973ea74-07d1-489b-918a-e7a3cfc970b9.jpg?v=1785469741","url":"https:\/\/voomisupply.com\/products\/3m-7100331749-quick-change-disc-3-in-36-grit-ceramic-50-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
