CGW 48034 7" Dia x 7/8" 50-Grit Aluminum Oxide Brown Fiber Disc

The CGW 48034 is a heavy-duty fiber disc designed for on-metal grinding and finishing. Sized at 7 inches in diameter with a 7/8 inch arbor, this disc features a 50-grit aluminum oxide grain intended for rapid stock removal while maintaining cool-cutting action on steel surfaces. Its construction combines sharp, heat-treated aluminum oxide grain with a heavy-duty vulcanized fiber backing, which supports consistent performance under high RPM operation.

Electrostatic coating on the grain helps promote uniform abrasive distribution and attachment to the backing, contributing to steadier performance during extended grinding tasks. This disc is suitable for applications requiring aggressive material removal on ferrous metals, with a focus on productivity and controlled heat generation to minimize workpiece discoloration. When selecting discs, consider RPM compatibility—this product is rated for up to 8600 RPM—along with the 7/8" arbor size to ensure proper fitment on compatible grinders or polishing machines.

Packaging specifies the format as Each with a box quantity of 25, making it convenient for maintenance workflows that require multiple discs per job or periodic replenishment. The combination of 7" diameter, 50-grit aluminum oxide, and fiber backing provides a balance between aggressiveness and durability for metal-finishing tasks, particularly where a stout backing is advantageous to sustain abrasive integrity under heavier pressures. Always follow equipment manufacturer guidelines for mounting and operating speeds to ensure safe use and optimal results.
