Part of the Big Cat series, it uses 40-grit aluminum oxide abrasive on a cloth backing with a phenolic backing plate for rigidity and heat resistance. The threaded 5\/8-11 arbor hole mounts directly to standard angle grinders. Rated at 8,600 RPM maximum, this disc delivers consistent coarse-grade cutting action across flat and contoured surfaces. Fabricators, welders, and metal finishing technicians reach for this disc when they need fast stock removal without multiple tool changes.\u003c\/p\u003e\u003cp\u003eThe WEILER 50833 is built for weld removal and surface preparation on fabricated steel and stainless steel workpieces. The Type 27 flat profile keeps the disc face at a low angle to the workpiece, making it well suited for flush grinding of weld beads and mill scale removal on flat plate and structural shapes. It is commonly used in fabrication shops, ironworking, and maintenance environments where a single disc needs to handle both heavy grinding and blending passes.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e40-grit coarse aluminum oxide abrasive for fast, aggressive stock removal\u003c\/li\u003e\n\u003cli\u003eType 27 flat profile optimized for surface grinding and weld flush work\u003c\/li\u003e\n\u003cli\u003ePhenolic backing plate provides rigidity and supports high-load grinding passes\u003c\/li\u003e\n\u003cli\u003eCloth backing on flaps resists tearing under heavy pressure\u003c\/li\u003e\n\u003cli\u003e5\/8-11 threaded arbor hole fits standard angle grinder spindles\u003c\/li\u003e\n\u003cli\u003e8,600 RPM maximum speed rating for use on 7-inch angle grinders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use on angle grinders with a 7-inch capacity and a 5\/8-11 threaded spindle.

Thread the 5\/8-11 arbor onto the grinder spindle and tighten with the appropriate spanner wrench per the grinder manufacturer's instructions. Always verify the grinder's no-load RPM does not exceed the 8,600 RPM disc rating before operation. Inspect the disc for damage before each use and replace if any flaps are torn or the backing plate is cracked.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDisc Diameter\u003c\/strong\u003e: 7 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCenter Hole Thread Size\u003c\/strong\u003e: 5\/8-11\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: 40\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: Aluminum Oxide\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: Cloth with Phenolic Backing Plate\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAttachment Type\u003c\/strong\u003e: Threaded Arbor Hole\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 8,600\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDisc Color\u003c\/strong\u003e: Brown\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplications\u003c\/strong\u003e: Weld Removal, Surface Preparation\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Steel, Stainless Steel\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: 0.7 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: 50833\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WEILER","offers":[{"title":"Default Title","offer_id":51541458321714,"sku":"50833","price":40.43,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9ae41373e231ce309947b45cc7c13792.jpg?v=1785876692","url":"https:\/\/voomisupply.com\/products\/weiler-50833-flap-disc-40-grit-7-inch-type-27","provider":"Voomi Supply","version":"1.0","type":"link"}
