The CGW 42361 4-1/2" x 7/8" Type 29 36-Grid Zirconia Flap Disc is designed for aggressive material removal on ferrous metals. It features a premium zirconia alumina grain bonded to a durable poly/cotton backing, a combination that supports efficient stock removal while contributing to a cleaner finish. The zirconia concentration provides higher aggressive cutting action, making these discs well-suited for heavy-duty applications where fast material removal is needed without sacrificing control.
A key attribute is the Type 29 flap construction, which offers a flared profile that maintains grinding efficiency and helps maintain consistent contact with the workpiece. An active grinding aid is included to aid cool cutting under light pressure, potentially reducing heat buildup and improving surface finish during extended use. This disc is sized for 4-1/2 inches in diameter with a 7/8 inch arbor, and is rated for up to 13,300 RPM, aligning with standard power tools used in metal fabrication and maintenance tasks.
Recommended for situations requiring rapid stock removal on steel and similar metals, these flap discs are intended for aggressive use and heavy-duty applications. When selecting a flap disc, ensure the tool and mounting hardware match the 4-1/2" diameter and 7/8" arbor, and observe appropriate shop practices for grit size and grinding pressure to maintain disc life and minimize surface damage. The packaging is listed as individual discs in boxes of ten, which supports convenient bulk stocking for maintenance workflows.
