Designed for 4.5" angle grinders, this 100-pack delivers consistent, industrial-grade performance across applications like rust removal, deburring, and finishing, all while exceeding ANSI and EU quality standards. ## 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. The European material is superior due to its uniform particle size and premium blend of ingredients. - Designed to meet industrial standards, our high-quality flap discs are recommended to be used with angle grinders sized 4.5”.
