The CGW 48232 4" Zirconia Blue Fiber Disc is designed for aggressive material removal and blending on metal surfaces, particularly working with welds on steel and stainless steel. This 4-inch diameter wheel-like disc fits standard 5/8-inch arbors and is intended for high-speed applications typical of angle grinders, making it suitable for shop and fabrication environments where fast stock removal is needed.
Its construction combines a high concentration of zirconia with heat-treated aluminum oxide grain. This combination provides enhanced cutting action and heat resistance, helping to maintain effective performance under extended use. The zirconia grain also fractures in a controlled way as the disc wears, promoting a consistent cutting action throughout the life of the disc rather than fading quickly. The result is a disc that supports efficient blending of welds and a range of metal surfaces, including both mild steel and stainless steel, when used with the appropriate technique and wheel RPMs.
For practical use, select a 36-grit configuration to balance material removal with surface finish. The specified RPM of 15,300 ensures the disc operates within safe speed ranges for its 4" diameter and 5/8" arbor size. This item is packaged in box quantities of 25 discs, offering economical stocking for maintenance, repair, and operations settings. When selecting discs, confirm compatibility with your grinder’s arbor size and operational RPM to ensure safe and effective performance.
