Measuring 4-1\/2 inches in diameter with a 7\/8-inch arbor hole, this disc runs at an angled grinding position typical of Type 29 geometry, which increases surface contact and stock removal compared to a flat Type 27 profile. The Z3 zirconia grain is a self-sharpening abrasive that maintains cut rate longer than standard aluminum oxide, making it well-suited for sustained grinding on mild steel, stainless steel, and weld seams. At 80 grit, it removes material quickly while leaving a workable surface finish. Discs are sold in a box of 10.\u003c\/p\u003e\u003cp\u003eThis flap disc is used in fabrication shops, welding operations, and metal finishing applications where consistent cut-down of welds, burrs, or surface scale is required. The angled Type 29 profile is preferred when working on flat stock or large surface areas where a more aggressive bite angle improves productivity. It is a common consumable for grinders used by welders, ironworkers, pipefitters, and metal fabricators working on both light structural and sheet metal work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eType 29 angled profile for increased contact and aggressive stock removal\u003c\/li\u003e\n\u003cli\u003eZ3 zirconia alumina grain — self-sharpening for extended disc life\u003c\/li\u003e\n\u003cli\u003e80 grit for fast material removal with a workable finish\u003c\/li\u003e\n\u003cli\u003e4-1\/2 inch diameter with standard 7\/8-inch arbor — fits most small angle grinders\u003c\/li\u003e\n\u003cli\u003eUSA made Z3 grain construction\u003c\/li\u003e\n\u003cli\u003eSold in a box of 10 discs\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use on standard 4-1\/2-inch angle grinders with a 7\/8-inch arbor.

Verify the grinder RPM rating meets or exceeds the disc's maximum RPM rating before use. Wear appropriate PPE including a face shield, gloves, and hearing protection. Inspect the disc for damage before each use and do not use a disc that shows cracking, missing flaps, or a damaged hub.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 4-1\/2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eArbor Size\u003c\/strong\u003e: 7\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDisc Type\u003c\/strong\u003e: T29 (Type 29)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAbrasive Grain\u003c\/strong\u003e: Z3 Zirconia Alumina\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 80\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight (each)\u003c\/strong\u003e: 0.19 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQuantity per Box\u003c\/strong\u003e: 10\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 65533242325\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: CGW\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 42325\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CGW","offers":[{"title":"Default Title","offer_id":51342783742258,"sku":"42325","price":69.92,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310470868.jpg?v=1782006496","url":"https:\/\/voomisupply.com\/products\/cgw-42325-zirconia-flap-disc-4-5in-t29-80-grit-10pk","provider":"Voomi Supply","version":"1.0","type":"link"}
