Designed for 4.5" angle grinders, these 80 grit discs deliver industrial-grade durability and precision, outperforming traditional resin fiber discs. Sold in a bulk 100-pack, they meet ANSI and EU standards, making them ideal for professionals in automotive, construction, and fabrication sectors. ## Description Flap discs are used in heavy stock removal, usually weld removal. They outperform Resin Fiber Discs due to their increased lifetime. Resin Fiber discs are only two dimensional, once the abrasive surface wears down the product is finished. To achieve a finish equivalent to a resin fiber disc always use a flap disc one grit coarser. E.g. if the operator is running a 60 grit resin fiber disc try a 40 or 50 grit flap disc. ## Features - Benchmark Abrasives 4-1/2" x 7/8" T29 flap discs are ideal for surface blending, beveling, grinding, deburring, edge chamfering, finishing, stock removal, etc. - Zirconia flap discs are manufactured using European zirconia cloth.
