The Full Face Diamond Faceting Lap with 1/4"-20 Screwback is full face diamond sanding disc, a professional-grade lapidary faceting and cabbing tool designed for precision grinding, shaping, and polishing of gemstones, glass, ceramics, quartz, jade, agate, and other hard materials. Unlike segmented laps, this full face diamond sanding disc lap provides maximum contact area and uniform wear for smooth, accurate, and chip-free finishes. The 1/4"-20 screwback mount ensures quick, secure, and perfectly balanced attachment to most faceting machines and flat lap grinders.
