CGW 48106 is a 4-1/2-inch diameter zirconia fiber disc designed for high-velocity grinding and blending on ferrous metals. Its 7/8-inch arbor size fits compatible right-angle grinders commonly used in workshop and maintenance environments. The disc leverages a high concentration of zirconia grain and heat-treated aluminum oxide, delivering improved cutting action and resistance to heat buildup during extended grinding sessions. The zirconia grain fractures in a controlled manner, providing a consistent grinding experience across the life of the disc and helping to maintain steady material removal on welds and adjacent surfaces.
This 80-grit accessory is particularly well-suited for blending welds and finishing on carbon steel and stainless steel, where heat generation and material distortion are considerations. The design emphasizes balanced performance between stock removal and surface finishing, making it a versatile choice for metal fabrication, fabrication repair, and maintenance tasks that require efficient grinding with durable grain. When selecting discs, verify arbor size, grit, and diameter to ensure compatibility with your grinder and the target workpiece, as these factors influence cut rate, finish quality, and disc life.
Compatible with standard 4-1/2-inch diameter flap or fiber disc applications that use 7/8-inch arbor hardware. Packaged as a single disc or in bulk quantities per box (25 discs per box as specified), this product supports routine maintenance and shop floor stocking. Proper grinding technique and a suitable backing pad are recommended to maximize performance and minimize heat-related effects on the workpiece and disc.
