CGW 41725 4-1/2" X 7/8" Type 29 80-Grit ZPC Zirconia Flap Disc

CGW 41725 is a 4-1/2 inch diameter Zirconia flap disc designed for high-performance material removal on steel surfaces. It features a Type 29 depressed center configuration with a 7/8 inch arbor/shank size, enabling compatibility with standard angle grinders. The zirconia grain and poly/cotton backing provide durability and a consistent finish during grinding and blending tasks, supporting efficient material removal while maintaining control over edge wear. The 80-grit construction is suitable for aggressive deburring, rust removal, and surface preparation, helping to achieve a steadier stock removal rate without excessive heat buildup when used within recommended RPM ranges. This disc is intended for steel applications, and its design aims to balance cutting aggressiveness with smooth finishing where a flatter face is needed to tackle contoured or curved surfaces. The combination of zirconia grains and a robust backing helps resist loading and provides a tougher working surface under typical shop conditions. Practically, users should mount this disc on compatible equipment at up to the rated RPM to ensure safe operation and optimal performance. The package is offered as individual units, with box quantities typically aligning to 10 discs per box, supporting bulk purchases for ongoing fabrication or maintenance tasks.
