CGW 42114 4" X 3/8"-24 Type 27 60-Grit Z3 Zirconia Flap Disc

CGW 42114 4" X 3/8"-24 Type 27 60-Grit Zirconia Flap Disc combines a durable poly/cotton backing with premium Zirconia Alumina grain to deliver efficient material removal on steel surfaces. This flap disc is designed for aggressive grinding while maintaining a relatively smooth finish, thanks to the zone-specific Type 27 configuration that optimizes contact with curved surfaces. The zirconia concentration supports high stock removal, making it suitable for heavy-duty applications where faster material removal is essential.

The disc features an active grinding aid, which helps keep the cutting edge cooler under light pressure, potentially reducing heat buildup during sustained grinding tasks. This can be particularly beneficial when working with steel where heat management impacts workpiece distortion and wheel life. The combination of grit size (60) and zirconia grain provides balance between aggressive cutting and sandable finish, suitable for preparatory work or heavy material removal before finer finishing steps.

Compatibility and packaging details indicate a 4" diameter with a 3/8"-24 arbor, Type 27 profile, and a gauge of 60 grit. The product is sold in packaged units, with ten discs per box, aligning with workshop and maintenance department stocking practices. When selecting for use, ensure compatibility with a 4" flap disc tool setup and verify arbor size and thread pitch prior to operation. Regular inspection for wear and disc integrity is recommended to maintain consistent performance during prolonged grinding tasks.
