Sold in a box of 10, each disc measures 4.5 inches in diameter with a 7\/8-inch arbor hole and carries a 50-grit abrasive rating. The disc is rated to 13,300 RPM, making it compatible with standard 4.5-inch angle grinders used in fabrication and weld prep environments. The Predator series is designed for fast weld removal while maintaining disc life beyond what standard flap discs typically deliver. Metal fabricators, welders, and maintenance professionals are the primary installers and operators of this product.\u003c\/p\u003e\n\u003cp\u003eThis flap disc is well suited for use on mild steel, high-alloy steel, nickel alloy, and stainless steel applications. The 50-grit designation places it in the coarse category, making it appropriate for heavy stock removal, weld seam grinding, and surface conditioning before secondary finishing passes. It performs in both shop fabrication settings and field repair scenarios where angle grinder access is available. The hard-edge construction maintains disc geometry under lateral pressure, which is useful during weld flush work and edge blending on structural steel components.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e50-grit abrasive for aggressive stock removal and weld grinding\u003c\/li\u003e\n  \u003cli\u003eHard-edge construction maintains shape under lateral load\u003c\/li\u003e\n  \u003cli\u003eRated to 13,300 RPM for use with standard 4.5-inch angle grinders\u003c\/li\u003e\n  \u003cli\u003eCompatible with mild steel, high-alloy steel, nickel alloy, and stainless steel\u003c\/li\u003e\n  \u003cli\u003eSold in a box of 10 discs for shop and job-site stocking\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with 4.5-inch angle grinders accepting a 7\/8-inch arbor.
