Type SF

These stones with a very fine grain size are recommended for further surface treatment after using DF or WP stones. They`re made from ground alumina only in a single grain size of 1200. SF grinding stones are very soft and the manufacturer guarantees that they do not scratch and are very suitable for working with diamond paste. However, due to their softness, they decrease relatively quickly. They can be used manually, but also with sawing devices. When working with these stones, we recommend using oil for working with grinding stones, which prevents the clogging of grinding stones with dirt and increases the grinding performance and quality of the treated surface.
