CGW 48529 4-1/2 in diameter by 7/8 in arbor zirconia blue fiber disc spindle pack delivers a high-performance grinding option for blending and material removal on welds, steel, and stainless steel. This spindle pack uses a zirconia-aluminum oxide blend with a uniform grain structure designed for repeated cutting action and consistent performance across the disc’s life. The result is a wheel that maintains aggressive cutting characteristics while offering better heat resistance, helping to manage heat buildup during extended grinding sessions.
The discs feature a 4-1/2 in diameter with a 7/8 in arbor size, making them compatible with standard spindle mandrels used in a variety of stationary and handheld grinding setups. Zirconia grain is known for its fracturing properties, which promote a steady supply of sharp edges as the disc wears, contributing to dependable material removal from weld beads and between metal surfaces. The blue fiber backing is designed to provide support and tolerance for high-speed operation, supporting consistent performance at elevated RPMs.
For practical use, the discs are packaged in quantities that align with shop stocking needs, with a box quantity of 100 per bundle. Operators should verify spindle compatibility and RPM suitability for their specific tools and workpieces, and follow established grinding practices to manage heat and surface finish. This product is positioned for facility maintenance and shop-floor applications where welding prep, cleanup, and metal finishing are routine tasks.
