Built on a flexible polyester and nylon web backing, this 1.5-inch diameter non-woven disc uses aluminum oxide abrasive grain with Clean Bond resin technology to deliver a smear-free finish without loading or glazing. At a coarse grade, it provides moderate material removal while the high-loft nylon fiber construction extends disc life beyond standard woven alternatives. The disc is rated to 30,000 RPM and connects via a Type R attaching system for fast, tool-free changes.\u003c\/p\u003e\u003cp\u003eThis disc is suited for metal fabrication, weld blending, deburring, and surface prep work across a wide range of materials including 300 and 400 series stainless steel, hard and soft carbon steels, tool steels, titanium, super alloys, and fiberglass or composite substrates. It mounts on die grinders, inline grinders, straight grinders, and handheld disc sanders, making it a practical choice for both shop and field service work where consistent surface quality is required across varied base materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eTR (Type III) quick-change system with Type R attaching button for tool-free disc swaps\u003c\/li\u003e\n\u003cli\u003eAluminum oxide abrasive grain with Clean Bond resin for smear-free, consistent finishes\u003c\/li\u003e\n\u003cli\u003eHigh-loft nylon fiber construction extends service life compared to standard non-woven discs\u003c\/li\u003e\n\u003cli\u003eFlexible polyester and nylon web backing conforms to irregular and curved surfaces\u003c\/li\u003e\n\u003cli\u003eCoarse grade provides moderate material removal on metals, alloys, and composites\u003c\/li\u003e\n\u003cli\u003e30,000 RPM maximum speed rating compatible with common pneumatic and electric grinders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with die grinders, inline grinders, straight grinders, and handheld disc sanders that accept a TR (Type III) quick-change Type R attaching system.

Confirm the tool spindle speed does not exceed the 30,000 RPM disc rating before mounting. Inspect the disc and mandrel for damage before each use, and ensure the attaching button is fully seated and locked prior to operation. Always use appropriate eye protection and follow applicable shop safety requirements when operating angle grinders or inline tools.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDisc Diameter\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Aluminum Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAbrasive Type\u003c\/strong\u003e: Non-Woven\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Coarse\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBacking Material\u003c\/strong\u003e: Polyester and Nylon Web\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQuick-Change Compatibility\u003c\/strong\u003e: TR (Type III)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAttaching System\u003c\/strong\u003e: Type R\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 30,000\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlexibility\u003c\/strong\u003e: Flexible\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDisc Color\u003c\/strong\u003e: Brown\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eButton Color\u003c\/strong\u003e: Black\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31191506\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 08834163540\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MERIT","offers":[{"title":"Default Title","offer_id":51557777998130,"sku":"08834163540","price":71.68,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/06fb7929d6ff285c36b650448a54cc5e.jpg?v=1786394952","url":"https:\/\/voomisupply.com\/products\/merit-abrasives-08834163540-quick-change-disc-1-5-in-coarse","provider":"Voomi Supply","version":"1.0","type":"link"}
