The most popular #330 pear-shaped tungsten carbide bur.
Komet's H7 (330) has a pear shape that is very effective for minimally invasive cavity preparations, ensuring that there isn’t too much tooth structure being removed. The 330 dental bur is also beneficial in removing old materials in the tooth, such as amalgam.
Carbide burs are made from tungsten carbide, which is three times stronger than steel. Their hardness makes them ideal for cutting work. H7 (330) tungsten carbide bur can maintain a sharp cutting edge and can be used multiple times without becoming dull. Unlike diamond burs, carbide burs don’t grind the enamel, leaving a smoother surface.
