6"x1/2" Aluminum Lap Disc for Sapphire, Ruby & Zircon Polishing

Aluminum Lap Disc is made from high-strength aluminum alloy, designed for durability, stability, and long service life in lapidary grinding and polishing applications.

The surface can be easily prepared using a steel saw blade or sandpaper, offering flexible and efficient operation for different polishing requirements.

Compared to zinc alloy laps, aluminum laps provide superior wear resistance and longer lifespan, although polishing powder adhesion is slightly lower. This makes them a cost-effective choice for long-term use.
