Weiler’s Tiger Paw abrasive flap discs are designed for aggressive performance on tough edge-grinding applications. The zirconium flap discs incorporate a high-performance grain and special poly-cotton backing to improve grain retention. Multiple layers of coated abrasive material wear away during use to expose sharp, fresh grains. The discs are available in 4-1/2" and 7" sizes with or without a 5/8"-11 nut in both Type 29 and 27 standard and Type 27 super high-density configurations. Applications include pipe beveling, edge chamfering, weld blending, grinding, deburring, stock removal, surface finishing and blending.
