CGW 42731 7" X 5/8"-11 Type 29 36-Grit Z3 Zirconia Flap Disc

The CGW 42731 flap disc is a 7-inch, 5/8-11 threaded Type 29 zirconia flap disc designed for heavy-duty material removal on steel. It features a premium zirconia alumina grain bonded to a durable poly/cotton backing, combining aggressive stock removal with a workable finish. The zirconia concentration is targeted to provide faster material removal while maintaining control, which can help reduce cycle times in demanding grinding tasks. An active grinding aid is included to promote cooler cutting under light pressure, potentially reducing heat buildup during extended use.

Constructed for aggressive use, this disc is suitable for high-production environments where durable performance is required. The Type 29 profile provides an angled grinding surface that can reach into contours and profiles, while the 36-grit size offers a balance between material removal rate and surface finish. The disc is designed for compatibility with standard 7-inch, 5/8-11 arbor tooling and is shipped in packaging that typically includes multiple discs for batch use in facilities that perform routine grind-and-finish operations.

When selecting this disc, ensure compatibility with your grinder’s RPM rating and mounting hardware. The product is specified for 8600 RPM operation and is intended for heavy-duty grinding on steel surfaces. Proper use includes applying light pressure to leverage the cooling aid and minimize heat generation, which can influence disc life and finish quality. For planning and inventory, note the package size (Each, Box Quantity 10) to align with procurement and stocking practices.
