Komet® H21 Flat End Fissue Carbide Preparation Bur

H21 is a parallel flat-end fissure carbide bur. Commonly known as #55, #56, #57, #58, and #59 Carbide Burs.

Carbide burs are made from tungsten carbide, which is three times stronger than steel. Their hardness makes them ideal for cutting work. H21 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.
