High speed fissure bur

High Speed Fissure Burs are rotary cutting instruments designed for use with high-speed (air-rotor) dental handpieces. They are ideal for rapid tooth preparation, cavity outlining, crown sectioning, and material removal, delivering efficient cutting with excellent control.

Available in tungsten carbide or diamond variants, fissure burs are a staple in operative dentistry, prosthodontics, endodontic access, and oral surgery.
