At 4.5 inches in diameter with a 5\/8-11 threaded arbor, it mounts directly to standard angle grinders used in fabrication, welding prep, and structural metalwork. The 40-grit abrasive delivers fast stock removal on mild steel, stainless steel, and other ferrous metals. The conical Type 29 geometry angles the abrasive surface toward the workpiece, increasing contact area and cutting efficiency compared to flat Type 27 discs. Metal fabricators, welders, pipefitters, and ironworkers are the primary installers and users of this disc.\u003c\/p\u003e\n\u003cp\u003eThis flap disc is suited for flat surface grinding, weld blending, edge work, and deburring operations in industrial, commercial, and heavy fabrication environments. The 40-grit designation makes it appropriate for initial material removal passes where aggressive cutting action is needed before moving to finer finishing grits. It is sold in a minimum quantity of 10 units per order, making it well suited for shop stocking and job-site supply.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eType 29 conical geometry increases contact angle for efficient stock removal on flat and contoured surfaces\u003c\/li\u003e\n  \u003cli\u003e40-grit abrasive provides aggressive cutting action for weld blending and initial surface preparation\u003c\/li\u003e\n  \u003cli\u003e4.5-inch diameter fits standard angle grinders with 5\/8-11 threaded spindles\u003c\/li\u003e\n  \u003cli\u003ePowerflex construction supports consistent performance across the disc life\u003c\/li\u003e\n  \u003cli\u003eSold in multiples of 10, suitable for shop inventory and ongoing production use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard angle grinders equipped with a 5\/8-11 threaded spindle and capable of accepting a 4.5-inch diameter flap disc.
