CGW 42551 5" X 5/8"-11 Type 27 36-Grit XL Z3 Zirconia Flap Disc

The CGW 42551 5" X 5/8"-11 Type 27 36-Grit XL Zirconia Flap Disc is designed for aggressive metalworking tasks, delivering material removal on steel surfaces with a focus on efficiency and finish consistency. This flap disc combines premium zirconia alumina grain with a durable poly/cotton backing, which supports long disc life and stable edge wear while promoting effective finishing action. The zirconia concentration in the abrasive contributes to higher stock removal rates compared with standard alumina blends, making it suitable for heavier workloads where speed matters. An active grinding aid helps reduce heat generation, enabling cooler cuts under light to moderate pressure, which can aid in extending the life of both the disc and the workpiece in challenging grinding scenarios.

The 5-inch diameter with a 5/8-11 arbor fits compatible angle grinders that accept Type 27, flat-to-convex profile discs. The Type 27 configuration is optimized for work on curved or contoured surfaces, giving access to a variety of shapes common in metal fabrication, automotive aftermarket, and general maintenance tasks. This disc is intended for aggressive use and heavy-duty applications, where rapid material removal is prioritized over fine finishing. When using this product, ensure proper guard protection and follow standard safety practices for grinding operations, as with all flap discs. Packaged with ten discs per box, this size suits shop environments where multiple units are required for production throughput or routine maintenance projects.
