The CGW 42331 is a 4-1/2 inch diameter, 5/8-11 threaded arbor Type 29 zirconia flap disc designed for aggressive stock removal on steel. This flap disc blends premium zirconia-alumina grain with a durable poly/cotton backing to balance material removal performance with a reliable finish. The zirconia concentration supports high stock removal rates, making it suitable for heavy-duty grinding tasks where rapid material removal is needed.
Key features include an active grinding aid that helps maintain cooler cutting action under light to moderate pressure, which can reduce heat buildup during extended grinding sessions. The Type 29 profile provides an offset grinding surface, enabling access to edges and contours while maintaining control on tougher surfaces. The disc is engineered for demanding applications where aggressive use is expected, and it is intended for use on common steel fabrication and maintenance tasks requiring efficient material removal.
Compatibility and packaging details indicate a 4.5 in diameter with a 5/8-11 threaded arbor, rated for up to 13,300 RPM, and sold in boxes of 10 discs. When selecting a flap disc, ensure the arbor size and disc type align with your grinder and job requirements, and verify RPM limits on the tool to maintain safe operation and disc life. For best results, use moderate pressure and consider allowing the flap layers to do the work rather than forcing the disc to grind aggressively, which can improve control and finish during heavy material removal.
