CGW 42562 5" X 7/8" Type 29 40-Grit XL Z3 Zirconia Flap Disc

The CGW 42562 flap disc is a 5 inch diameter, 7/8 inch arbor Type 29 flap disc designed for aggressive material removal on steel. It features premium Zirconia alumina grain bonded to a durable poly/cotton backing, which provides a balance of stock removal and a reasonable finish. The zirconia concentration helps promote faster material removal compared with standard abrasive grains, while the poly/cotton backing adds durability and flexibility to maintain consistent contact with the workpiece.

This disc incorporates an active grinding aid intended to promote cooler cutting and reduce heat buildup under light to moderate pressure. With a 40 grit specification, the disc is positioned for heavy-duty applications where stock removal is prioritized, and it is rated for up to 12,200 RPM, supporting fast, continuous grinding on compatible steel surfaces. The product is packaged as an individual disc, with a box quantity of 10 per order, making it suitable for stocking and repeated use in production or fabrication settings.

When selecting this disc, ensure the arbor size matches your grinder (7/8 inch) and that Type 29 shapes are appropriate for your work angle and grinding approach. The 5 inch diameter provides a compact yet efficient grinding surface, making it a fit for workpieces with limited access or in corner-fill operations where aggressive material removal is required. Maintain proper safety practices, and replace discs showing wear, damage, or glazing to preserve performance and safety.
