Part of the Tiger Angled series, it features a zirconia alumina abrasive at 60 grit, making it well-suited for coarse stock removal, weld blending, and surface conditioning. The phenolic backing provides rigid support during high-load grinding passes. The disc mounts via a 5\/8-11 threaded arbor hole and is rated to 13,000 RPM. At 4.5 inches in diameter and 0.28 pounds, it fits standard 4.5-inch angle grinders used daily in fabrication, maintenance, and field repair work.\u003c\/p\u003e\n\u003cp\u003eThis disc is used in light fabrication shops, structural steel work, pipe fitting, and maintenance applications where both mild steel and stainless steel surfaces require grinding or blending. The Type 27 flat profile keeps the disc parallel to the workpiece, making it effective for surface work and inside corners. The zirconia alumina grain self-sharpens during use, maintaining cut rate over the life of the disc. It is a single-piece packaged unit, sold individually, suited for professionals who stock specific grit ranges by job.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eZirconia alumina abrasive grain self-sharpens for sustained cut rate on steel and stainless steel\u003c\/li\u003e\n  \u003cli\u003eType 27 angled flap disc profile for flat surface grinding and blending\u003c\/li\u003e\n  \u003cli\u003e60 grit coarse grade for aggressive stock removal and weld blending\u003c\/li\u003e\n  \u003cli\u003ePhenolic backing for rigid support under high grinding pressure\u003c\/li\u003e\n  \u003cli\u003e5\/8-11 threaded arbor hole fits standard angle grinder spindles\u003c\/li\u003e\n  \u003cli\u003eRated to 13,000 RPM for use with 4.5-inch angle grinders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use on standard 4.5-inch angle grinders with a 5\/8-11 threaded spindle.
