The new ceramic grinders produce few vibrations, allowing for work at high rotation speeds. Their varied forms allow for flexible uses. For instance, the pear shape in the coarse, medium and fine strengths is suitable for working on large areas, while the cylindrical form is suitable for nail edges. The cylindrical grinders also have a protective groove to protect against injuries with rounded edges. Correctly handled, grinders can have a very long service life. Prevent the ceramics from striking each other, since this may cause fine cracks. Use an autoclavable stand for further processing after cleaning, such as the stainless steel grinder stand.
