The CGW 42735 7" x 5/8"-11 Type 29 80-Grit Z3 Zirconia Flap Disc is designed for aggressive stock removal on steel surfaces, delivering efficient material elimination with a cooler cut when used with light pressure. Its Zirconia grain on a durable poly/cotton backing balances durability and surface finish, supporting sustained grinding actions typical of heavy-duty applications. The Type 29 profile is optimized for grinding ridges, welds, and irregular contours, allowing access to angled surfaces and challenging work areas.
Construction features include premium Zirconia Alumina grain arranged for rapid material removal and a backing that provides both strength and a better finish. The disc is configured with a 7-inch diameter and a 5/8-11 arbor, compatible with common right-angle grinders used in fabrication and maintenance tasks. The included 80-grit specification targets heavier material removal rather than fine finishing, making it suitable for initial shaping, deburring, and smoothing of rough welds or scaler surfaces. An active grinding aid is present to help reduce heat buildup and prolong disc life under moderate pressure.
Practical use considerations include ensuring proper wheel compatibility with your grinder’s arbor size and RPM limits; this disc is rated for up to 8600 RPM, a parameter to observe for safe operation. The package quantity is ten discs per box, with each disc ready for immediate use in standard 7" flap-disc workflows. This flap disc is appropriate for heavy-duty metalworking tasks that require fast stock removal while maintaining control over the workpiece finish, particularly on steel surfaces where aggressive grinding is needed.
