Description
Highly purified 99.99+ Zinc to which is added grain refiners, tougheners and deoxidizers. Gentler and smoother to use than prior zinc laps, but still more aggressive then the tin alloys. Produces very rapid prepolishes, and has been used for cutting with the “Watercut” Diastiks.
Lighter in weight than the heavy cast laps, they offer better balance, smoother running, and easier, more predictable use due to their finer and uniform grain sizes. In time, they will probably obsolete the cast products.
