The CGW 48012 fiber disc is a 4-1/2 inch diameter, 7/8 inch arbor size abrasive disk designed for high-stock removal on steel with a cool-cutting action. It uses a sharp, heat-treated aluminum oxide grain electrostatically coated onto a heavy-duty vulcanized fiber backing to maximize life and performance during industrial grinding tasks. This construction helps maintain efficient material removal while minimizing heat buildup, which can affect workpiece hardness and surface finish.
The 36-grit specification indicates a coarse abrasive profile intended for rapid material removal on metal surfaces, making the disc suitable for applications like deburring, edge chamfering, and weld-prep where aggressive cutting is required. The combination of premium aluminum oxide and a robust fiber backing supports consistent performance under demanding grinding conditions, and the electrostatic coating aids grain retention during use. At a maximum operating speed rated for 13,300 RPM, users should ensure proper mounting and adherence to safety guidelines for wheel-type or fiber disc usage.
This disc is packaged as individual pieces with a 25-discount box quantity, facilitating inventory management for shops with higher throughput. When selecting replacement discs, verify the correct diameter, arbor size, grit, and material compatibility to ensure effective stock removal without compromising workpiece integrity. Regular inspection and proper storage help preserve abrasive performance over time, and following manufacturer mounting and usage recommendations is essential for achieving the described results.
