CGW 49031 1-1/2" X 2-1/2" X 5/8"-11 Type 18 A16R 16-Grit Aluminum Oxide Resin Plug

The CGW 49031 is a resin-bonded grinding plug designed for use in metal finishing and deburring tasks in hard-to-reach areas. This particular accessory features an aluminum oxide abrasive grain, selected for its balance of cut rate and durability when grinding metals. The plug is sized with a 1-1/2 inch diameter and 2-1/2 inch overall thickness, and it uses a 5/8-11 arbor/shank to fit compatible spindle and tool configurations. Its Type 18 designation indicates a shaped abrasive configuration suited for surface treatment in restricted spaces, while the 16 grit and R (relatively hard) grade describe a coarser contact feel intended for material removal and finishing in confined areas. The maximum operating RPM is listed at 24,100, providing a practical speed limit to maintain control and avoid overheating during use.

This resin plug is constructed to withstand metalworking environments, where grinding in tight or contoured spots is required. Aluminum oxide grain offers general-purpose performance on ferrous and some non-ferrous metals, with a profile that supports both material removal and a finishing touch in corners or recessed surfaces. Given its Type 18 form, it is best paired with equipment that accommodates an exposed abrasive face oriented toward the workpiece, enabling effective contact in restricted geometries. When selecting this plug, consider the need for consistent alignment with the tool’s arbor size and the space available around the work area to ensure safe, effective grinding.

Packaging indicates a single-piece packaging size with ten units per box, which can support batching tasks or stocking needs in maintenance workflows. Compatible use relies on matching the 5/8-11 arbor to compatible tools and ensuring the workpiece geometry affords proper access to the abrasive face. Regular inspection for wear and re-contact with the workpiece is advised to maintain effective performance and control during metal finishing tasks.
