Built around alumina zirconia mineral with a grinding aid, this 4-inch, 80-grit disc delivers faster material removal than standard aluminum oxide abrasives across all metal types. Heavyweight polyester-backed flaps resist breakdown under sustained pressure, giving the disc extended service life in demanding tasks such as weld removal, beveling, and sharp-edge work. The quick-change attachment system reduces downtime between disc swaps, making it a practical choice for production-rate grinding environments. Licensed trade professionals and experienced fabricators install and operate this disc on compatible angle grinders.\u003c\/p\u003e\u003cp\u003eThis flap disc is suited for use on ferrous and non-ferrous metals in both fabrication shop and field settings. Common applications include weld seam removal, edge chamfering, and surface blending where a finished appearance is needed in a single pass. The Type 29 conical profile increases contact surface on flat workpieces, improving consistency across large weld beads and flat plate work. It is used in structural steel fabrication, pipe work, and general metal finishing where both aggressive material removal and a blended surface finish are required in one step.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAlumina zirconia mineral with grinding aid cuts faster than aluminum oxide on all metal types\u003c\/li\u003e\n\u003cli\u003e80-grit abrasive balances aggressive stock removal with a blended surface finish\u003c\/li\u003e\n\u003cli\u003eHeavyweight polyester-backed flaps extend disc life under high-pressure applications\u003c\/li\u003e\n\u003cli\u003eFlap design combines grinding and surface blending into a single operation\u003c\/li\u003e\n\u003cli\u003eQuick-change system speeds disc replacement and reduces downtime\u003c\/li\u003e\n\u003cli\u003eType 29 conical profile maximizes flat-surface contact area\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use on angle grinders accepting 4-inch quick-change flap discs with a Type 29 profile.
