The CGW 48027 fiber disc is a 5-inch diameter, 7/8-inch arbor sized abrasive disc designed for high-volume metal finishing on steel surfaces. It uses premium aluminum oxide grain that’s electrostatically coated onto a heavy-duty vulcanized fiber backing, delivering both long life and efficient stock removal while maintaining a cooler cutting action during use. This combination of grain and backing helps balance aggressive material removal with reduced heat buildup, which supports better workpiece control and extended disc life in demanding grinding tasks.
Key construction details include a 100‑grit aluminum oxide grain and a heavy-duty fiber backing that supports aggressive grinding while remaining flexible enough to conform to contoured surfaces. The disc is engineered for high RPM operation, rated up to 12,200 RPM, making it suitable for fast material removal on steel applications in maintenance and fabrication environments. The product is packaged as individual discs, with a box quantity of 25, which can aid in inventory planning for job sites and shops that require reliable, consistent performance from their grinding tooling.
When selecting this disc, users should consider compatibility with standard 7/8-inch arbor tooling on 5-inch grinding machines. Ensure proper mounting and balance to maximize performance and minimize vibration. As with all abrasive products, follow appropriate PPE and manufacturer guidelines for wheel speed, workpiece material, and disc usage duration to avoid line grinding defects or disc glazing. This disc is intended for use on metal surfaces, particularly steel, where higher stock removal is needed along with a controlled heat profile during material removal.
