The CGW 41704 Zirconia Flap Disc is a 4-1/2 inch diameter, 7/8 inch arbor size Type 27 flap disc designed for aggressive material removal on ferrous metals. Its zirconia grain paired with a poly/cotton backing provides durable cutting action and a stable finish surface, suitable for steel applications where efficient material removal and a finer final texture are desired. The 60-grit formulation supports rapid stock removal while delivering a workable finish on welded joints, rust, and scale.
The construction combines zirconia abrasive grain with a sturdy backing to maintain dressing resistance and reduce heat buildup during extended grinding sessions. The Type 27 configuration offers an angled grinding surface for accessing contoured areas and achieving a flatter contact with the workpiece, which helps control swarf and improve consistency across the job. Compatible with standard 7/8 inch arbor grinders, this disc is rated for up to 13,300 RPM, aligning with typical power tools used in metal fabrication and maintenance tasks.
When selecting this disc, consider the backing material’s influence on durability and finish quality, as well as the balance between aggressive stock removal and the resulting surface texture. Each package contains ten discs, allowing for multi-piece jobs or project continuity without frequent restocking. This disc is intended for use on steel and similar ferrous metals, and it should be matched to the grinder’s speed and mounting hardware to ensure safe operation and optimal performance.
