CGW 48017 4-1/2" Dia x 7/8" 100-Grit Aluminum Oxide Brown Fiber Disc

The CGW 48017 aluminum oxide fiber disc is a 4-1/2 in. diameter, 7/8 in. arbor/shank finishing disc designed for high stock removal with a cool cutting action on steel. This 100-grit disc uses sharp, heat-treated aluminum oxide grain that is electrostatically coated onto a heavy-duty vulcanized fiber backing, providing robust performance under demanding grinding applications. The combination of premium abrasive and durable backing aims to balance material removal with controlled heat generation, helping to maintain workpiece integrity during grinding tasks.

Typical use cases include deburring, surface finishing, and light material removal on ferrous metals where a relatively aggressive cut is needed without excessive heat buildup. The abrasive is designed for use on compatible 4-1/2 inch cutoff/pertinent grinders and is specified at a maximum operating speed of 13300 RPM to support consistent performance when used within rated conditions. Each package contains individual discs, with box quantities of 25, offering a convenient density for maintenance and production environments.

Compatibility notes: ensure the disc size and shank are appropriate for the grinder being used, and confirm the mounting system aligns with the disc’s arbor/shaft specification. For best results, use with compatible backing material and follow standard PPE and grinder safety practices during operation. The stated specifications—4.5 inch diameter, 7/8 inch arbor, 100-grit aluminum oxide on a fiber backing—define the product’s identity and expected performance envelope for metalworking finishing tasks.
