The CGW 42505 is a 5-inch diameter, 7/8-inch arbor Type 27 zirconia flap disc designed for aggressive stock removal on steel surfaces. It combines premium zirconia alumina grain with a durable poly/cotton backing to provide both effective material removal and a smoother finished surface, thanks to the backing’s flex and the zirconia’s self-sharpening properties. An active grinding aid is included to help maintain cooler cutting under light pressure, which can contribute to reduced heat buildup during longer grinding sessions and help minimize discoloration and warping of the workpiece when used appropriately.
Construction features a zirconia grain concentration that supports fast material removal while aiming to balance finish quality and disc life. The Type 27 profile is optimized for grinding on flat, contoured, and welded areas, with the 5
