The CGW 48122 Zirconia blue fiber disc is designed for heavy-duty material removal and blending on ferrous metals. Sized at 7 inches in diameter with a 7/8 inch arbor, this 36-grit disc uses a high concentration of zirconia and heat-treated aluminum oxide grain to deliver sustained cutting action and improved heat resistance. The zirconia grain fractures in a controlled way, helping the disc maintain consistent performance across its life and reducing glazing during extended use. This makes it suitable for applications that require efficient stock removal on welds, steel, and stainless steel surfaces while minimizing heat buildup that can affect workpieces and tools.
Practically, the disc’s construction supports aggressive grinding with a finer finish on weld seams and adjacent areas. The 7/8" arbor and 7" diameter are compatible with standard right-angle or die grinders designed to accept fiber discs, and the 36-grit grade is appropriate for blending and deburring tasks where rapid material removal is balanced with surface texture. When using these discs, operators should follow appropriate grinding speeds and inspect the disc for heat damage or edge wear to ensure consistent performance across the full life of the wheel. The package listing indicates the product is sold as individual discs, with 25 discs per box, which can help with budgeting and stocking.
This product is positioned for facility maintenance environments where durable, heat-resistant grinding tools are needed for steel and stainless steel workpieces. While compatibility details aren’t expanded beyond the stated arbor size and disc diameter, users should confirm their grinder’s speed and arbor fit before mounting to avoid polishing inconsistencies or equipment strain.
