The CGW 48015 is a 4-1/2 inch diameter, 7/8 inch arbor brown fiber disc designed for metalworking applications where aluminum oxide grain provides efficient material removal and a cooler cut on steel. This disc combines a sharp, heat-treated aluminum oxide grain with a heavy-duty vulcanized fiber backing, which supports aggressive grinding while maintaining durability under high RPM operation.
Constructed to balance grind efficiency with long life, the grain is electrostatically coated to the backing. This construction helps promote uniform wear and consistent stock removal across the working surface, making it suitable for grinding, deburring, and finishing tasks on ferrous metals. The 60-grit specification targets a middle-ground finish, offering a productive blend of material removal rate and surface texture without excessive gouging.
Practical use considerations include running at high speed, with the rated RPM of 13,300 supported by the disc design. The package is listed as individual discs with a 25-piece box quantity, which supports bulk purchasing for shop environments. When selecting a disc, verify the wheel diameter, arbor size, and grit to ensure compatibility with your grinding tool and the intended finishing result. Proper mounting and adherence to manufacturer RPM recommendations help maximize performance and disc life.
