It is rated for a maximum of 15,100 RPM and is graded extra coarse, making it well-suited for aggressive material removal while maintaining consistent cut throughout the disc's life. The non-woven backing provides compliance and helps the disc conform to contoured or irregular surfaces. This disc is designed for use by metal fabricators, machinists, weld prep technicians, and general shop personnel working with portable or bench-mounted rotary tools equipped with a quick-change arbor system.\u003c\/p\u003e\n\u003cp\u003eThis disc is suited for a range of surface preparation tasks on metal workpieces in both production and job-shop environments. Typical applications include deburring sharp edges after cutting or punching operations, grinding down weld beads, refining surface finish after rough grinding, and blending transitions between surfaces. The extra coarse grade makes it most effective in early-stage material removal rather than fine finishing. It is a single-unit package intended for use wherever a compact 2-inch quick-change disc fits the tooling at hand.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePrecision shaped ceramic abrasive grain delivers consistent cut rate and extended disc life compared to conventional abrasives\u003c\/li\u003e\n  \u003cli\u003eExtra coarse grade for aggressive deburring, grinding, and blending\u003c\/li\u003e\n  \u003cli\u003eNon-woven unitized wheel construction conforms to contoured and irregular surfaces\u003c\/li\u003e\n  \u003cli\u003e2-inch diameter fits standard quick-change arbor systems on portable rotary tools\u003c\/li\u003e\n  \u003cli\u003e15,100 RPM maximum speed rating supports high-speed tool compatibility\u003c\/li\u003e\n  \u003cli\u003eSuitable for deburring, grinding, refining, and blending operations on metal\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use abrasive disc for portable and bench-mounted rotary tools equipped with a 2-inch quick-change arbor interface.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and disc changes should be performed by qualified shop personnel or tooling technicians following the tool manufacturer's arbor mounting instructions. Always power down and disconnect the rotary tool from its power source before mounting or removing the disc. Do not exceed the 15,100 RPM maximum speed rating printed on the disc or in the tool specification. Confirm the quick-change arbor is in proper working condition and fully secured before operating.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Diameter\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Precision Shaped Ceramic\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Extra Coarse\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Type\u003c\/strong\u003e: Unitized Wheel (Non-Woven)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 15,100 RPM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Applications\u003c\/strong\u003e: Deburring, Grinding, Refining, Blending\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.029 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: 7100290649\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51539495223602,"sku":"7100290649","price":19.1,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/da9d0eabf057b1796628a6ef98b9a688.jpg?v=1785841722","url":"https:\/\/voomisupply.com\/products\/3m-7100290649-quick-change-disc-2-in-ceramic-extra-coarse","provider":"Voomi Supply","version":"1.0","type":"link"}
