The SI Series features a unique inverted cone design with a flat top and tapered sides that widen toward the tip.Manufactured using high-quality natural diamond grit electroplated onto a medical-grade stainless steel shank, these burs provide exceptional concentricity and balance.This design ensures smooth, vibration-free operation at high speeds, typically up to 450,000 RPM, protecting the handpiece turbine while providing a high-quality surface finish.

Features
Mechanical Retention: Ideal for producing undercuts at the junction of the pulpal floor and lateral walls in Class I, II, and V cavity preparations.
Surface Flattening: Efficiently used for flattening pulpal and gingival walls, ensuring a stable base for restorative materials.
Precision Cutting: The diamond coating allows for faster, smoother cutting with extreme precision, leaving a higher polished surface than carbide equivalents.
Friction Grip (FG) Shank: Standardized 1.6 mm shank diameter to fit high-speed dental turbines (Airotors).
Grit Variations: Commonly available in Medium (Blue band) for general preparation and Coarse (Green band) for rapid enamel reduction.
Durability & Sterilization: Built for long-lasting cutting ability and is fully autoclavable for clinical infection control.
