It carries an 80-grit zirconia alumina abrasive — a medium-grade material that cuts aggressively while holding up under heat and pressure. The phenolic backing provides rigid support, keeping the disc stable at speeds up to 8,600 RPM. The arbor hole measures 7\/8 inches, fitting standard angle grinder spindles. Part of the Tiger Big Cat HD series, this disc is built for demanding fabrication and weld prep work where consistent stock removal and disc longevity matter.\u003c\/p\u003e\n\u003cp\u003eThis flap disc is suited for metalworking applications in fabrication shops, structural steel work, and field welding environments. Its Type 27 flat profile is the right choice for surface grinding and blending on flat or slightly contoured workpieces. The zirconia alumina abrasive performs well on carbon steel and stainless steel, making it a practical option for both production grinding and finishing passes. Licensed tradespeople and fabricators working to AWS or shop-floor weld prep standards will find this disc fits standard 7-inch angle grinders.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eType 27 flat profile for surface grinding and weld blending\u003c\/li\u003e\n  \u003cli\u003e80-grit zirconia alumina abrasive — medium grade, aggressive cut with good disc life\u003c\/li\u003e\n  \u003cli\u003ePhenolic backing for rigid support and stability at high RPM\u003c\/li\u003e\n  \u003cli\u003eRated to 8,600 RPM maximum operating speed\u003c\/li\u003e\n  \u003cli\u003eHigh-density flap construction (Tiger Big Cat HD series) for extended service life\u003c\/li\u003e\n  \u003cli\u003eFits standard 7\/8-inch arbor hole angle grinders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use on steels and stainless steel.
