It measures 4.5 inches in diameter and mounts on a 5\/8-11 inch arbor. The disc is built with multiple layers of jumbo blue zirconia cloth flaps that continuously expose fresh, sharp abrasive points as the disc wears. The reinforced fiberglass backing plate provides structural rigidity, and each disc is balance-tested to minimize vibration during grinding and finishing operations. Sold in a pack of 10, the 71932 is suited for metalworking professionals who need consistent stock removal and surface finishing performance.\u003c\/p\u003e\u003cp\u003eThis flap disc is intended for use with standard right angle grinders in fabrication, welding prep, and metal finishing applications. The Type 29 geometry — a conical, depressed-center profile — delivers better surface contact at lower angles than a flat Type 27 disc, making it well suited for blending welds and working on flat or contoured surfaces. The 80 grit rating positions this disc between aggressive stock removal and controlled finishing, handling both rough surface cleanup and finer finishing work. It is appropriate for residential and commercial metalworking environments where speed and disc longevity are priorities.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eJumbo blue zirconia abrasive cloth provides fast cutting action and extended disc life compared to standard aluminum oxide flap discs\u003c\/li\u003e\n\u003cli\u003eType 29 depressed-center profile improves surface contact at working angles typical of right angle grinder use\u003c\/li\u003e\n\u003cli\u003eMultiple cloth flap layers continuously expose new abrasive points as material wears away\u003c\/li\u003e\n\u003cli\u003eReinforced fiberglass backing plate supports structural integrity under load\u003c\/li\u003e\n\u003cli\u003eEach disc balance-tested for vibration-free operation\u003c\/li\u003e\n\u003cli\u003ePack of 10 discs reduces per-unit cost for high-volume users\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with right angle grinders fitted with a 5\/8-11 inch arbor, which is the standard spindle thread for 4.5-inch angle grinders used in metalworking and fabrication trades.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eMounting and disc changes must be performed with the grinder powered off and unplugged or battery removed. Verify the grinder's rated RPM meets or exceeds the disc's maximum RPM rating before use. Always install the disc with the proper flange and locking nut per the grinder manufacturer's instructions, and confirm the disc is seated securely before starting the tool. Eye protection, a face shield, and appropriate PPE are required during operation per applicable ANSI and OSHA standards.\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\u003eArbor Size\u003c\/strong\u003e: 5\/8-11 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 80\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Zirconia (Jumbo Blue Zirconia Cloth)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDisc Type\u003c\/strong\u003e: Type 29 Depressed Center\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBacking Plate\u003c\/strong\u003e: Reinforced Fiberglass\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 10 discs\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: EA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 3.7 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: FORNEY INDUSTRIES INC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 71932\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"FORNEY","offers":[{"title":"Default Title","offer_id":51559882391858,"sku":"71932","price":106.63,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/75c347289da6d49fc1b998488406ca8d.jpg?v=1786443488","url":"https:\/\/voomisupply.com\/products\/forney-industries-inc-71932-flap-disc-80-grit-4-5-in-10-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
