Measuring 4.5 inches in diameter with a 5\/8 inches-11 threaded hub, this disc fits standard angle grinders used daily in fabrication, welding, and metal finishing work. The 60-grit zirconia abrasive delivers a fast cut rate with good disc life, making it a practical choice for heavy grinding passes on steel and other ferrous materials. The conical T29 profile keeps the abrasive cloth at an angle to the workpiece, improving contact on flat surfaces and weld seams.\u003c\/p\u003e\u003cp\u003eThis flap disc is suited for metal fabrication shops, structural steel work, shipbuilding, and general weld blending applications. It performs on mild steel, stainless steel, and similar ferrous metals where consistent material removal and surface conditioning are required. Sold individually, it is a standard consumable for angle grinder operators who need a reliable 60-grit disc for medium-to-heavy grinding tasks.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eType 29 conical profile for improved contact on flat and curved surfaces\u003c\/li\u003e\n\u003cli\u003e60-grit zirconia alumina abrasive for fast, aggressive stock removal\u003c\/li\u003e\n\u003cli\u003e4.5-inch diameter fits standard angle grinders with 5\/8 inches-11 arbor\u003c\/li\u003e\n\u003cli\u003eZirconia grain self-sharpens during use for extended disc life compared to aluminum oxide\u003c\/li\u003e\n\u003cli\u003eThreaded 5\/8 inches-11 hub for direct mount without a separate backing nut on compatible grinders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with angle grinders equipped with a 5\/8 inches-11 threaded spindle, which is the standard arbor size for 4.5-inch angle grinders across most major tool brands.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eFlap discs are installed and serviced by metalworkers, fabricators, and maintenance trades.
