Hi-Tech Diamond Backing Plates are essential accessories for your flat lap machine. These sturdy, rigid acrylic plates are designed to provide a perfectly flat backing for your adhesive-backed diamond smoothing discs, polishing pads, and standard grinding laps. Having multiple backing plates allows you to pre-mount your entire sequence of grits, making grit changes fast and effortless during the cabbing process. Precision-machined with a standard arbor hole, they run true without wobbling, ensuring smooth, consistent results and extending the life of your abrasive discs.
