Built on a rigid polyester cloth backing with a Y-weight rating, it carries a zirconia alumina abrasive grain at 120 grit for fine-to-medium stock removal, weld blending, deburring, and surface conditioning. An advanced resin bond system holds the grain firmly under load, and a lubricating grinding aid reduces heat buildup during extended passes. Rated to 20,000 RPM, this disc is suited for handheld disc sanders in fabrication, maintenance, and finishing applications.\u003c\/p\u003e\n\u003cp\u003eThis disc is used across metal fabrication and finishing workflows where controlled material removal and surface quality matter. It performs on 300 and 400 series stainless steel, brass, bronze, hard carbon steels, soft carbon steels, and glass. Typical applications include weld blending on stainless structural components, deburring machined parts, and light stock removal before final finishing. It is intended for use with handheld disc sanders accepting TR or Type R quick-change attachments. The disc is sold individually but carries a minimum order quantity of 50 units.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eZirconia alumina abrasive grain provides consistent cut rate and longer service life compared to aluminum oxide on hard metals\u003c\/li\u003e\n  \u003cli\u003eRigid polyester Y-weight backing resists flex during aggressive grinding passes\u003c\/li\u003e\n  \u003cli\u003eAdvanced resin bond retains grain under high pressure and heat\u003c\/li\u003e\n  \u003cli\u003eLubricating grinding aid reduces heat buildup and smearing on stainless and non-ferrous metals\u003c\/li\u003e\n  \u003cli\u003ePower-Lock TR (Type III) and Type R quick-change attachment for fast disc swaps without tools\u003c\/li\u003e\n  \u003cli\u003eRated to 20,000 RPM for safe use on standard handheld disc sanders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with handheld disc sanders equipped with TR (Type III) or Type R quick-change attachment systems.

Always verify the tool spindle speed does not exceed the 20,000 RPM disc rating before use. Inspect the disc for damage, delamination, or loading before each use and replace immediately if defects are found. Use appropriate eye protection, gloves, and respiratory protection when grinding or deburring metal surfaces.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDisc Diameter\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 120\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Fine \/ Medium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Zirconia Alumina\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAbrasive Type\u003c\/strong\u003e: Coated\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: Y\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDisc Color\u003c\/strong\u003e: Blue\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eButton Color\u003c\/strong\u003e: Black\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlexibility\u003c\/strong\u003e: Rigid\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTrimmable\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eQuick-Change Compatibility\u003c\/strong\u003e: TR (Type III) \/ Type R\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 20,000\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMachine Compatibility\u003c\/strong\u003e: Handheld Disc Sander\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: R887D\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.018 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 50\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31191506\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: MERIT ABRASIVES\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 08834167120\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MERIT","offers":[{"title":"Default Title","offer_id":51560799732018,"sku":"08834167120","price":3963.7,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/63593716c663c21ae671f135130ef0c4.jpg?v=1786457875","url":"https:\/\/voomisupply.com\/products\/merit-abrasives-08834167120-quick-change-disc-120-grit-3-in","provider":"Voomi Supply","version":"1.0","type":"link"}
