The CGW 42542 5" x 7/8" Type 27 40-Grit XL Zirconia Flap Disc is designed for aggressive material removal on ferrous metals. This premium flap disc utilizes zirconia alumina grain on a durable poly/cotton backing to balance stock removal with a quality finish. The zirconia concentration contributes to higher material removal rates while the XL (extra-large) format provides extended disc life for heavy-duty grinding tasks. An active grinding aid is included to help maintain cooler cutting conditions under light to moderate pressure, which can help reduce heat buildup and prolong the tooling and workpiece life when used as part of an appropriate grinding routine.
Constructed for high-demand steel applications, the 5" diameter with a 7/8" arbor shank is compatible with standard right-angle grinders used in fabrication, maintenance, and workshop environments. The Type 27 profile offers a depressed-center shape optimized for working on flat and curved surfaces, enabling more versatile contact geometry across welds, rivets, and irregular contours. This package includes ten discs per box, enabling you to equip multiple machines or stock up for ongoing projects without frequent reorders.
When selecting this flap disc, ensure proper grinding parameters and personal protective equipment are observed. The combination of fast material removal and a cool-cutting aid helps maintain control during aggressive stock removal, but users should monitor heat generation and work with light pressure to maximize disc life and achieve the desired finish. Confirm compatibility with your grinder’s arbor size and RPM rating to avoid over-speed conditions and ensure safe operation.
