CGW 48533 5" Dia x 7/8" 24-Grit Zirconia Blue Fiber Disc Spindle Pack

The CGW 48533 5" Zirconia Blue Fiber Disc Spindle Pack is a high-performance wheel accessory designed for surface finishing and material removal on metal workpieces. This 5-inch diameter abrasive disc features a 7/8-inch arbor and a 24-grit zirconia-blend grain, optimized for blending welds on carbon steel and stainless steel, as well as other metal surfaces. The zirconia grain, paired with heat-treated aluminum oxide characteristics, provides robust cutting action and resistance to heat buildup, helping maintain consistent performance through the disc’s life.

What sets this disc apart is its grain structure, which fractures in a way that preserves a steady cutting action as the disc wears. This behavior supports predictable material removal and surface texture, reducing the need for frequent disc changes during mid-range grinding tasks. The blue fiber backing contributes to disc integrity under typical high-speed operation, while the spindle-style form factor facilitates quick mounting on compatible grinders used in facility maintenance and metal fabrication environments.

In practical terms, this disc is suitable for blending weld seams and finishing both mild steel and stainless steel surfaces where controlled aggressiveness and heat resistance are important. It is packaged as a spindle disc with a specified RPM rating of 12,200, aligning with common high-speed grinders used in workshop settings. When selecting replacements, ensure the 5" diameter and 7/8" arbor match your tool and that you apply appropriate safety practices for high-speed grinding, including eye protection and dust management. The package configuration is listed as an individual disc, with a box quantity of 50 for bulk stocking and easy reordering.
