CGW 42356 4-1/2" X 5/8"-11 Type 27 120-Grit XL Z3 Zirconia Flap Disc

CGW 42356 is a high-performance flap disc designed for aggressive stock removal on steel surfaces. This 4-1/2 inch, 5/8-11 hub size Type 27 disc features 120-grit zirconia alumina grain bonded to a durable poly/cotton backing. The zirconia concentration provides efficient material removal, while the poly/cotton backing supports longevity and a smoother finish during extended operation. An integrated grinding aid helps reduce heat buildup and allows for cooler cutting with light pressure, which can contribute to longer tool life and better control in demanding grinding tasks.

The Type 27 configuration is oriented for off-angle grinding, making it well-suited for contoured shapes and weld seams where access is limited. The combination of premium zirconia alumina grain with a robust backing delivers both sustained stock removal and a reasonable surface finish for continued work without frequent disc changes. This disc is intended for aggressive use and heavy-duty applications, particularly in steel fabrication or maintenance environments where faster material removal is a priority.

Compatibility and packaging details indicate a 4-1/2 inch diameter with a 5/8-11 mounting thread, compatible with standard right-angle grinders. The product is packaged for single-unit or bulk distribution, depending on channel, with a typical configuration described as a box quantity of 10. When selecting discs, consider working speed and safe operating RPM to match the 13,300 RPM rating and to ensure proper grinding pressure and technique for optimal results.
