CGW 42725 is a 7 inch diameter Type 29 zirconia flap disc designed for aggressive stock removal on steel. It features a zirconia alumina grain bonded to a durable poly/cotton backing, which supports both material removal and a smoother finish during grinding. The zirconia concentration delivers high stock removal while the backing helps maintain disc integrity under heavy use. An active grinding aid is included to promote cooler cutting and reduce chatter under light pressure, which can help manage heat buildup during extended grinding sessions.
This flap disc is specified with a 7/8 inch arbor and 80 grit, making it suitable for rapid material removal on ferrous metals while still offering enough finish quality for subsequent operations. It is rated for up to 8,600 RPM, aligning with typical high-speed grinder applications. The packaging indicates individual discs, with multiple units per box, which supports workshop inventory stocking and batch replacement.
When selecting this disc, consider the need for aggressive material removal on steel and the potential for heat generation. Use with compatible high-speed angle grinders and employ light to moderate pressure to leverage theActive grinding aid’s cooling effect. Regularly inspect the disc for wear and tear, especially near the flange and edge areas, and replace if any cracks or glazing appear. This product is intended for general facility maintenance tasks that involve rapid deburring, rust removal, and roughing steps prior to finishing operations.
