The CGW 48530 is a spindle-pack set of 4-1/2" diameter by 7/8" arbor zirconia fiber discs designed for high-performance grinding on metal surfaces. These discs are intended to be mounted on a compatible spindle or backing hardware and used for blending welds and finishing on steel and stainless steel, delivering consistent material removal across the disc’s life.
Constructed with a high concentration of zirconia and heat-treated aluminum oxide grain, the discs are engineered for improved cutting action and heat resistance relative to standard aluminum oxide discs. The proprietary grain fracturing behavior promotes steady grinding and sustained performance, helping to maintain an even finish as the disc wears. The fiber disc construction supports robust disc-life under typical metal-finishing applications, where heat buildup and rapid wear can be factors.
Typical use scenarios include blending and cleaning weld seams, deburring edges, and achieving a uniform surface finish on stainless and carbon steels. The product is specified as a 50-grit zirconia blend, with an 4.5" wheel diameter and 7/8" arbor/shank size, compatible with standard grinding machines that accept fiber discs of this arbor. The package is provided as individual discs within a 100-disc box, suitable for ongoing maintenance or shop-wide stocking. When selecting this disc, ensure the grinder’s RPM rating aligns with the disc’s maximum operating speed (13300 RPM) to maintain safety and performance standards.
