The CGW 48225 back-up pad is designed for use with 5 inch diameter resin fiber grinding discs that thread onto a 5/8-11 arbor. This medium-smooth rubber back-up pad supports coarse grinding grits and helps maintain consistent contact between the disc and the workpiece, contributing to more even material removal. The pad’s design incorporates spiral ribs that create contact points and channels for air flow, which helps reduce heat buildup and can extend disc life by an estimated 30% to 50% under appropriate use. Larger air holes further enhance cooling and improve abrasive life during extended grinding sessions.
When selecting a back-up pad, users have options to match contour needs and aggressiveness of grinding. Flexible rubber pads are recommended for contoured surfaces, while rigid pads are suited for more aggressive grinding applications where longer disc life is desired. The combination of material choice and ribbed air-flow design supports more efficient grinding, especially on uneven or curved workpieces, by maintaining stable disc-to-pad contact and aiding heat management.
Compatibility and basic specs: this back-up pad is sized for a 5 inch disc with a 5/8-11 arbor, rated up to 12,250 RPM, and packed as a single unit per package. For best results, verify the disc you intend to use matches the pad’s arbor size and the RPM range of your tools, and select the flexible or rigid variant based on your workpiece geometry. Maintaining proper air flow and ensuring clean, dry mounting surfaces will help maximize pad and disc life over time.
