The disc measures 4.5 inches in diameter with a 7\/8-inch arbor hole and runs a zirconia alumina abrasive cloth at 60 grit for coarse-grade cutting action. A phenolic backing supports the flap arrangement, maintaining disc shape and abrasive contact under load. Rated to 12,000 RPM, it handles the demands of sustained grinding on steel and stainless steel. Fabricators, welders, and metal finishing technicians are the primary users.\u003c\/p\u003e\u003cp\u003eThis flap disc is suited for weld removal and surface preparation on steel and stainless steel workpieces. The Type 27 flat profile provides flush grinding across flat surfaces and inside corners, making it a practical choice for weld bead blending, mill scale removal, and prep work before coating or inspection. It fits standard 4.5-inch angle grinders with a 7\/8-inch arbor. Both shop and field applications are supported given its compact form factor and single-unit packaging.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eZirconia alumina abrasive cloth delivers aggressive cut rate on ferrous metals\u003c\/li\u003e\n\u003cli\u003e60 grit coarse grade suited for weld removal and heavy surface preparation\u003c\/li\u003e\n\u003cli\u003eType 27 flat profile for flush grinding on flat and contoured surfaces\u003c\/li\u003e\n\u003cli\u003ePhenolic backing maintains disc integrity under continuous grinding loads\u003c\/li\u003e\n\u003cli\u003e12,000 RPM maximum speed rating compatible with standard 4.5-inch angle grinders\u003c\/li\u003e\n\u003cli\u003eBig Cat series construction for consistent abrasive performance across the disc life\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use on steel and stainless steel.

Before mounting, confirm the grinder RPM rating meets or exceeds 12,000 RPM and that the disc is free of damage. Mount the disc securely on the arbor and ensure the guard is in place before powering on. Do not exceed the maximum rated speed, and always follow ANSI B7.1 safety standards for abrasive wheel use.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDisc Diameter\u003c\/strong\u003e: 4.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCenter Hole Size\u003c\/strong\u003e: 7\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlap Disc Type\u003c\/strong\u003e: Type 27\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: Coarse\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Zirconia Alumina\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBacking Material\u003c\/strong\u003e: Cloth (Phenolic-Backed)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAbrasive Type\u003c\/strong\u003e: Coated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 12,000\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDisc Color\u003c\/strong\u003e: Blue\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Steel, Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplications\u003c\/strong\u003e: Weld Removal, Surface Preparation\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAttachment Type\u003c\/strong\u003e: Arbor Hole\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Big Cat\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.3 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: WEILER\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 96242\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WEILER","offers":[{"title":"Default Title","offer_id":51542378217778,"sku":"96242","price":22.67,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7846e148713b89ddf81cff2ee057d10a.jpg?v=1785899054","url":"https:\/\/voomisupply.com\/products\/weiler-96242-flap-disc-60-grit-4-5-inch-type-27","provider":"Voomi Supply","version":"1.0","type":"link"}
