The CGW 48039 fiber disc is a 7 inch diameter, 7/8 inch arbor aluminum oxide abrasive disc designed for dry grinding and finishing on steel and similar metals. The premium aluminum oxide grain is electrostatically coated to a heavy-duty vulcanized fiber backing, providing a balance of long life, high stock removal, and cool cutting action during use. This construction helps maintain material integrity by reducing heat buildup during material removal, which is particularly important when working with harder metals or delicate finishes.
The disc features 80-grit aluminum oxide abrasive and is intended for high-speed operation, rated up to 8600 RPM. Its rugged fiber backing supports consistent wear and provides good heat dissipation, contributing to predictable performance across multiple uses. Each package contains 25 discs, suitable for bulk maintenance tasks where consistent grit and backing are required to achieve the desired surface finish on metallic workpieces.
Practical considerations include selecting the correct 7/8 inch arbor/shank size for compatible grinders and ensuring appropriate wheel speed to match the disc rating. This disc is suited for metal fabrication, maintenance, and workshop applications where a durable, aggressive grinding action is needed while managing heat generation. Always follow manufacturer safety guidelines and PPE recommendations when mounting and using fiber discs to ensure safe and effective operation.
