CGW 48014 4-1/2" Dia x 7/8" 50-Grit Aluminum Oxide Brown Fiber Disc

CGW 48014 is a 4-1/2 inch diameter, 7/8 inch center arbor (shank) fiber disc engineered for heavy material removal on steel with a cool-cutting action. Constructed with sharp, heat-treated aluminum oxide grain Electrostatically coated onto a heavy-duty vulcanized fiber backing, this disc is designed to deliver long life and consistent stock removal while helping minimize heat buildup during grinding. The combination of oxide grain and durable backing makes it suitable for applications that require aggressive material removal without excessive loading, particularly on ferrous metals.

This 50-grit configuration provides a balance between material removal rate and a smoother finish, making it a practical choice for prep work, deburring, and surface finishing where a standard periphery grinding disc is appropriate. The 4-1/2" diameter and 7/8" arbor accommodate common angle grinders, and the discs are sold per piece with a box quantity of 25, helping maintain steady supply for maintenance or shop workflows. Because the abrasive is bonded to a tough fiber backing, users should monitor disc wear and replace when the backing begins to break down or the grain becomes glazed to ensure consistent performance.

In practical terms, this CGW brown fiber disc is suited for mid- to heavy-duty stock removal on steel components, with attention to proper wheel speed. Recommended operating RPMs for this size and grit are in the typical range for 4-1/2" fiber discs, and users should adhere to the grinder’s guidelines and PPE requirements when performing grinding operations on metal surfaces to maintain safe, productive work habits.
