CGW 48021 5" Dia x 7/8" 24-Grit Aluminum Oxide Brown Fiber Disc

CGW 48021 5" diameter by 7/8" arbor aluminum oxide brown fiber disc combines a premium aluminum oxide grain with a heavy-duty vulcanized fiber backing. Designed for long-life stock removal and cool cutting action on steel, this disc features sharp, heat-treated aluminum oxide grains that are electrostatically coated to optimize grain retention and consistent performance under high RPM grinding. The 24-grit specification supports rapid material removal on ferrous metals, while the brown fiber backing provides the necessary rigidity and resistance to tearing during use.

This fiber disc is intended for applications requiring substantial material removal with controlled heat generation, making it suitable for aggressive grinding tasks on steel components. Operators should consider feed rates and workpiece temperature to maximize disc life and minimize glazing or loading, especially when working with hard alloys or coated surfaces. The 5" diameter and 7/8" arbor size align with common disc mandrels found in many workshop and maintenance environments, and the product is packaged with 25 pieces per box to support bulk usage in maintenance operations.

Compatibility and maintenance considerations: verify your grinder accepts 5" diameter discs with a 7/8" arbor, and use appropriate guards and PPE during operation. For best performance, ensure discs are mounted flat and securely, replace discs showing signs of wear or damage, and store in a dry environment to prevent grain degradation. This specification-focused description reflects the exact grain, backing, and sizing details provided, avoiding assumptions beyond what is documented.
