CGW 42752 7" X 5/8"-11 Type 27 40-Grit XL Z3 Zirconia Flap Disc

The CGW 42752 7" X 5/8"-11 Type 27 40-Grit XL Zirconia Flap Disc is designed for aggressive material removal on steel surfaces. This flap disc uses premium zirconia alumina grain bonded to a durable poly/cotton backing, balancing bulk stock removal with a smoother finish. The zirconia concentration enhances cutting efficiency, helping to remove material more quickly than standard grain blends when used on steel. An active grinding aid is included to promote cooler cutting, which can reduce heat buildup under light pressure during extended use.

Built for heavy-duty grinding applications, the Type 27 profile facilitates substantial contact with the workpiece, making it suitable for contouring and deburring as well as rough shaping tasks. The combination of zirconia grain and a robust backing is intended to withstand demanding shop environments while providing consistent performance across multiple passes. This disc is sized for 7 inches in diameter with a 5/8-11 thread, a common standard for many angle grinders, and is rated for up to 8600 RPM to support quick material removal at higher speeds.

When selecting this flap disc, ensure compatibility with your grinder’s arbor and operating speed. The package quantity is 10 discs per box, which supports frequent resupply for ongoing fabrication or maintenance projects. Practically, it’s well-suited for aggressive use and heavy-duty applications where rapid stock removal on steel is a priority and where a cooler-cutting action under light pressure can help manage heat during extended use.
