Built on the Tornado-Z standard profile, this disc delivers consistent stock removal and long service life on ferrous and non-ferrous metals. It measures 4.5 inches in diameter with a 5\/8-11 threaded arbor hole and carries an 80-grit zirconium oxide abrasive that cuts fast while resisting heat buildup. Rated to a maximum of 13,300 RPM, it is suitable for use on standard right-angle grinders. Sold individually, with a box quantity of 10 units per case.\u003c\/p\u003e\n\u003cp\u003eThis flap disc is used in metal fabrication, welding shops, and general industrial maintenance where surface grinding, blending, and finishing on steel, stainless steel, and similar metals are required. The Type 29 angled profile increases surface contact on flat and contoured workpieces, making it well-suited for both heavy material removal and intermediate finishing passes. It is a common choice for welders, pipefitters, ironworkers, and general metal tradespeople working on structural steel, pipe, and sheet metal.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eZirconium oxide abrasive for fast cutting and extended disc life on metal\u003c\/li\u003e\n  \u003cli\u003eType 29 standard profile increases contact angle for aggressive stock removal on flat and curved surfaces\u003c\/li\u003e\n  \u003cli\u003e80-grit rating balances material removal with surface finish quality\u003c\/li\u003e\n  \u003cli\u003e4.5-inch diameter with 5\/8-11 arbor fits standard right-angle grinders\u003c\/li\u003e\n  \u003cli\u003e13,300 RPM maximum speed rating for safe operation on common grinder models\u003c\/li\u003e\n  \u003cli\u003eSold individually with box quantity of 10\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with right-angle grinders accepting a 4.5-inch disc and a 5\/8-11 threaded spindle.
