The CGW 49042 aluminum oxide resin plug is a heavy-duty grinding accessory designed for use on metals in hard-to-reach areas. This plug-style wheel features a 2 inch diameter and 3 inch face width with a 5/8-11 arbor, making it compatible with standard mounting hardware on compatible power tools and benches. The wheel is constructed with aluminum oxide grain, which provides a balance of cut rate and durability for metal finishing tasks, particularly in confined spaces where larger wheels aren’t practical. Its 18R A16R designation indicates a particular hardness and shank/format specification used by CGW, and the 16-grit size suggests a coarser abrasive suitable for rapid material removal or initial shaping in tight channels or corners. The rated operating speed of 18,100 RPM reflects the wheel’s performance envelope and helps ensure safe usage within the tool’s recommended operating range.
Because this is a resin-bonded plug wheel, it relies on a resin matrix to hold abrasive grains and maintain structure under load during grinding or finishing operations. This makes it appropriate for applications where metal surface material needs to be removed efficiently without altering surrounding profiles. The packaging lists the wheel as an individual item within a box quantity of 10, which is a practical consideration for stocking and replacement in maintenance workflows. When selecting this abrasive, verify compatibility with your grinder or straight-rotary tool and ensure the arbor and mounting hardware match the 5/8-11 specification.
Use scenarios include deburring, edge blending, and surface finishing on accessible metal areas where a traditional wheel cannot reach. Operators should monitor wheel condition during use, adhere to manufacturer RPM recommendations, and follow standard safety practices for grinding: ensure proper PPE, secure mounting, and routine inspection for cracks or wear before assembly. The product identity and grain composition are fixed aspects of this CGW offering, and no additional specifications beyond those provided are assumed for compatibility or performance.
