These burs consist of a medical-grade stainless steel shank with a cylindrical working head coated in natural diamond crystals. Because they do not taper, they are the instrument of choice for procedures requiring strict vertical orientation, such as Class I cavity preparations or specific crown and bridge work.

Features
Parallel Wall Geometry: Unlike tapered burs, the SF series ensures that the internal walls of a cavity or preparation are perfectly parallel, which is critical for the retention and resistance of certain restorative materials.
Flat End Cutting: The flat tip allows for the creation of a smooth, flat pulpal or gingival floor, providing a stable foundation for fillings or dental prosthetics.
Superior Concentricity: Manufactured to exacting standards to ensure a vibration-free rotation, which protects the handpiece turbine and provides a cleaner cut on the tooth surface.
High-Speed Efficiency: Designed with a standard 1.6 mm Friction Grip (FG) shank, making them compatible with standard high-speed air turbines (Airotors).
Durability: The diamond grit is bonded using a proprietary electroplating process that ensures high particle retention and a long-lasting, sharp cutting edge.
