The CGW 48125 Zirconia Blue Fiber Disc is designed for fast, efficient material removal on metal surfaces, including weld blends on steel and stainless steel. With a 7-inch diameter and a 7/8-inch arbor, this disc is built to fit common upgrade and fabrication grinders, enabling consistent performance in finishing operations where higher heat resistance and aggressive cutting action are required.
The disc combines a high concentration of zirconia grain with heat-treated aluminum oxide to deliver twice the cutting action of standard premium aluminum oxide discs and to maintain performance under elevated temperatures. Zirconia’s fracturing characteristics promote a steady cutting action over the life of the disc, helping to produce uniform finishes as material is removed. This makes it well-suited for applications that involve blending welds and contouring metal surfaces where heat management and sustained grit action are important.
Practical considerations include its 60-grit specification, which positions it for coarse to medium-finishing tasks. The disc is intended for use with 8600 RPM grinders, and it ships in boxed packaging with 25 discs per box, making it suitable for shop wide usage where multiple pieces are needed for ongoing projects. When selecting discs, ensure the 7/8-inch arbor/shank size matches your grinder’s arbor to guarantee secure mounting and optimal performance.
