The CGW 48102 Zirconia blue fiber disc is designed for light- to medium-duty grinding and blending on ferrous metals, including steel and stainless steel. With a 4-1/2 inch diameter and a 7/8 inch arbor, this 36-grit disc combines a high concentration of zirconia with heat-treated aluminum oxide grain to deliver consistent cutting action and improved heat resistance across the disc’s life. The zirconia blend is engineered to resist glazing and maintain effective material removal during extended use, making it suitable for weld blending, deburring, and surface refinement in fabrication and maintenance settings.
The disc’s construction emphasizes durable bonding and fracturing characteristics that promote a steady grind. As the disc wears, the grain fractures to expose sharp edges, helping maintain cutting efficiency and reducing the chance of clogging in weld and edge areas. This is particularly advantageous when working on welded joints or edges where aluminum oxide alone might dull quickly. Proper selection of a 36-grit zirconia disc supports faster material removal while still allowing controlled shaping and smoothing of welds and contours.
For practical use, ensure compatibility with 7/8" arbor grinders and verify RPM capability since this product is rated for up to 13,300 RPM. The packaging lists individual discs with a box quantity of 25, enabling inventory planning for maintenance or shop use. Proper use and mounting practices, including securing the disc to prevent run-out, help maximize performance and reduce vibration during grinding tasks.
