CGW 42354 4-1/2" X 5/8"-11 Type 27 60-Grit XL Z3 Zirconia Flap Disc

The CGW 42354 is a 4-1/2" diameter flap disc designed for aggressive material removal on steel surfaces. It utilizes a zirconia alumina grain bonded to a durable poly/cotton backing, a combination that supports both robust stock removal and a smoother finish. The zirconia concentration in the grain enhances cutting efficiency, enabling faster material removal compared with many standard blends, while the active grinding aid helps maintain cooler cutting action under light pressure. This disc is built around a Type 27, 60-grit configuration, suitable for use on right-angle grinders where a flatter grinding profile and controlled airflow are desirable for flat-to-countered welds or contoured surfaces.

Key construction features include the 4-1/2" wheel diameter with a 5/8-11 arbor size and a max operating speed of 13,300 RPM, making it compatible with common professional grinders used in metal fabrication and maintenance tasks. The zirconia-alumina blend and the poly/cotton backing are selected to provide a balance of stock removal rate and finishing capability, making this disc a practical choice for heavy-duty grinding, deburring, and finishing operations where rapid material removal is prioritized.

For buyers, this flap disc is sold in a package size of Each with a box quantity of 10 discs, enabling convenient inventory management and replacement planning for shop environments that demand steady throughput. When selecting discs, verify grinder arbor compatibility (5/8-11) and ensure the selected Type 27 disc aligns with your grinding angle and application. Regular inspection for wear and heat buildup is advised, and the disc should be used with appropriate PPE to ensure safe operation.
