CGW 41765 4-1/2" X 7/8" Type 29 80-Grit XL ZPC Zirconia Flap Disc

The CGW 41765 4-1/2" x 7/8" Type 29 80-Grit XL ZPC Zirconia Flap Disc is designed for aggressive material removal on steel surfaces. This flap disc uses zirconia grain for efficient stock removal and a poly/cotton backing that enhances durability and finish strength during grinding operations. The Type 29 configuration provides a shallower angle, enabling more aggressive material engagement and versatile control on curved and contoured workpieces.

Constructed to withstand demanding grinding tasks, the 80-grit zirconia blend offers a balance between material removal rate and a smoother finish compared with coarser grits. The XL designation indicates a larger or more robust flap arrangement, which can contribute to extended disc life under heavy use. When operated at the specified speed, the disc maintains stable performance for prolonged periods, helping to reduce downtime from frequent tool changes.

This flap disc is sized for 4-1/2" diameter with a 7/8" arbor, making it compatible with common angle grinders used in metal fabrication, maintenance, and repair settings. It is intended for steel applications and should be used following standard safety practices for powered grinding tools. Consider pairing this disc with appropriate PPE and ensuring the grinder is set to the maximum operating speed within the disc’s RPM rating to achieve consistent results.
