CGW 42744 7" X 7/8" Type 27 60-Grit XL Z3 Zirconia Flap Disc

The CGW 42744 7" X 7/8" Type 27 60-Grit XL Z3 Zirconia Flap Disc is designed for heavy-duty grinding on ferrous metal surfaces. Built with premium zirconia alumina grain bonded to a poly/cotton backing, this flap disc combines durability with a smoother finish while delivering high stock removal thanks to its zirconia concentration. The XL construction is intended to endure aggressive use, making it suitable for demanding metalworking tasks where rapid material removal is a priority.

The disc features a Type 27 profile, optimized for grinding on contoured surfaces and at appropriate angles, with a 7" diameter and 7/8" arbor/shank size. An active grinding aid is included to help maintain cooler cutting action under light pressure, which can contribute to extended wheel life and reduced heat buildup on the workpiece. The 60-grit specification indicates a balance between material removal rate and a workable finish, appropriate for initial shaping or heavy material removal on steel and similar metals.

Usage considerations include selecting the correct RPM for the wheel—8600 RPM as indicated—and ensuring compatibility with standard 7" flap disc setups. This package is sold as individual discs, typically in boxed quantities of 10, and is suitable for applications where aggressive stock removal and durable edge retention are required. While this description reflects the provided product data, always verify the manufacturer’s instructions and machine compatibility before use to ensure safe operation and optimal results.
