Magma Diamond Tool offers 6-inch Snail Lock Puzzle Edge Polishing Disks for flat and bullnose edges. Each has a pressure of 2.5 bar. According to the company, during a test on engineered stone they stopped at 1500 and they did not need to use the 3000 or buff. “We found that running 3000 was not necessary,” stated Magma Diamond Tool. “On granite, the 3000 was a must after 1500; however, the buff on granite showed to be even more significantly better.”
