[HIGH-QUALITY MATERIALS] The abrasive uses the high temperature sintered aluminium oxide, which improves sandpaper wear resistance by 30% compared to conventional aluminium oxide materials.
[OPTIMAL CRAFTSMANSHIP] Traditional flap disc uses 105mm Fiberglass backing. Our flap disc uses a smaller 90mm Fiberglass backing, resulting in a 10% increase in the utilization of the flap disc.
[AUTHENTIC JUMBO] Sandpaper flaps are wider than traditional ones, traditional flaps are only 13 to 15 mm, and ours is 20 mm. There are more flaps, most brands have only 72 flaps, and we have reached 86. So the sandpaper weight is increased by 50% and the durability is increased by 50%.
[ADAPTABILITY] 4-1/2 Inch diameter x 7/8 Inch arbor size flap disc is compatible with angle grinders operatable of up to 13,300 RPM, T27 Type, 60 Grit, fits for most air and electric grinders.
[QUALITY ASSURANCE] Made in accordance with ANSI safety requirements.
