CGW 48101 4-1/2" (114 mm) diameter, 7/8" (22 mm) arbor zirconia blue fiber disc delivers aggressive material removal on metalwork with controlled heat. This 24-grit disc uses a high concentration of zirconia plus heat-treated aluminum oxide grain to achieve twice the cutting action of premium aluminum oxide discs while maintaining heat resistance during extended grinding sessions. The zirconia grain’s fracturing characteristics provide a consistent cutting action throughout the life of the disc, helping maintain steady material removal and finish when blending welds on steel and stainless steel surfaces.
Designed for use on ferrous and some nonferrous metals, these discs are well-suited for weld blending and light to medium grinding tasks where heat buildup can be a concern. Practical considerations include running at up to the recommended speed (13300 RPM) and ensuring proper disc seating on a compatible 7/8" arbor machine or compatible tool. Manufacturer-specified packaging indicates the discs are sold in individual units with a 25-disc box quantity, which supports bulk stocking for fabrication workflows.
This CGW disc is constructed for metalworking environments requiring a durable, heat-resistant abrasive option that can sustain cutting action through repeated use. When selecting this disc, verify the machine’s arbor size and the appropriate RPM range to maintain safe operation and achieve the desired surface finish on welds and edge-weld blends.
