It measures 4.5 inches in diameter and mounts via a 5\/8-11 inches arbor. The disc is constructed with multiple layers of jumbo blue zirconia cloth flaps that continuously expose fresh, sharp grinding points as the disc wears. A reinforced fiberglass backing plate provides structural support, and each disc is balance-tested to minimize vibration during grinding and finishing operations. The package contains 10 discs and weighs 4.1 pounds.\u003c\/p\u003e\n\u003cp\u003eThis flap disc is suited for both rough material removal and fine finishing on metal surfaces. The zirconia abrasive construction is appropriate for fabrication shops, welding operations, and general metalworking applications where fast stock removal and extended disc life are priorities. Each disc is laminated using automated equipment for consistent flap placement and balanced performance across the full working life of the disc.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eType 29 depressed-center geometry for aggressive contact angle on flat and contoured surfaces\u003c\/li\u003e\n  \u003cli\u003eJumbo blue zirconia cloth flaps for fast cutting and extended service life\u003c\/li\u003e\n  \u003cli\u003eMultiple flap layers continuously expose new sharp abrasive points as disc wears\u003c\/li\u003e\n  \u003cli\u003eReinforced fiberglass backing plate for durability under load\u003c\/li\u003e\n  \u003cli\u003eBalance-tested for vibration-free grinding and finishing\u003c\/li\u003e\n  \u003cli\u003eFits standard 5\/8-11 inches arbor right-angle grinders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with right-angle grinders equipped with a standard 5\/8-11 inches arbor.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified operator familiar with angle grinder safety practices.
