CGW 42124 4" X 5/8" Type 29 60-Grit Z3 Zirconia Flap Disc

CGW 42124 is a 4-inch diameter flap disc designed for aggressive stock removal on steel and related metals. This Type 29 wheel features a zirconia alumina grain embedded on a durable poly/cotton backing, which supports both effective material removal and a reasonable finish. The zirconia concentration enhances wear resistance and cutting efficiency, making it suitable for heavy-duty grinding tasks where material removal rate is a priority. An active grinding aid is included to promote cooler cutting under light pressure, helping to manage heat generation during extended grinding sessions.

Constructed to balance performance and long-term usability, the disc is sized for 4" wheels with a 5/8"-11 arbor and a Type 29 configuration, which typically provides an aggressive grinding angle and efficient material removal. The 60-grit specification indicates a coarse surface intended for rapid stock removal rather than fine finishing. For practical use, users should apply appropriate grinding pressure and maintain consistent contact to leverage the wheel’s cooling aid and zirconia grain benefits while monitoring heat buildup on the workpiece. The package is sold per disc with a box quantity of 10, making it suitable for shop-wide rotation and replacement planning.

This product is compatible with standard 4" flap disc systems that accept 5/8"-11 arbors and Type 29 profiles. Always verify arbor size and wheel compatibility on your grinder before use, and follow all safety and PPE guidelines when operating disc grinding tools to ensure safe handling and disposal of spent grinding materials.
