CGW 48124 7" Dia x 7/8" 50-Grit Zirconia Blue Fiber Disc

The CGW 48124 is a 7 inch diameter fiber disc designed for high-performance surface finishing on metal substrates. Engineered with a dense mix of Zirconia and heat-treated Aluminum Oxide grain, this disc delivers efficient cutting action and exceptional heat resistance, making it well-suited for blending welds and working on steel and stainless steel. The Zirconia grain is engineered to fracture in a controlled manner, providing consistent cutting action throughout the disc’s life and helping to maintain steady material removal as it wears.

With a 7/8 inch arbor opening, this disc is intended for use on compatible power tools and is rated for high RPM operation to sustain productive grinding and blending tasks. The combination of zirconia and the abrasive bond is chosen to balance aggressive material removal with耐 heat buildup, which can influence disc life and finish quality. The package is organized for bulk purchasing and distribution, with 25 discs per box, supporting shop-wide maintenance and fabrication workflows.

When selecting grit and disc type, consider the material and weld characteristics you’re addressing: this disc excels in blending welds and finishing on both carbon steel and stainless steel surfaces. Ensure proper tool compatibility, appropriate guard use, and adherence to safety practices for wheel selection, mounting, and operation. Proper inspection and wheel dressing or conditioning may help maintain consistent performance over the disc’s useful life.
