Dental Carbide Burs FG Cylindrical Cross-cut Designed for integration with high-speed handpieces operating within a range of 120,000 to 300,000 RPM, our FG (Friction Grip) burs deliver exceptional cutting efficiency for time-intensive procedures. Engineered for rapid and substantial material removal, these burs are the primary choice for critical tasks such as endodontic pulp opening, the removal of existing metal or ceramic crowns, and the surgical sectioning of wisdom teeth where extensive enamel and dentin reduction is required. Furthermore, they provide the necessary precision for initial cavity preparation, refined tooth shaping, and high-velocity surface polishing, ensuring a streamlined clinical workflow
1. High-Velocity Cutting Efficiency (ISO 314 Standard): Engineered for high-speed friction-grip handpieces operating up to 300,000 RPM. The optimized rake angles allow for effortless cutting through enamel (VHN≈ 300-400) and restorative materials, significantly reducing chair-time.
2. Precision Shank Specifications (ISO 1797): Features a high-precision 1.60mm (±0.01mm) Friction Grip (FG) shank. Available in Standard (19mm), Short (16.5mm), and Extra Long (25mm) configurations to ensure perfect compatibility with all global high-speed turbine brands.
3. Ultra-Low Concentricity Tolerance (T.I.R.): Every bur is tested to ensure a Total Indicated Runout (T.I.R.) of less than 0.02mm. This near-perfect concentricity eliminates "chatter" and vibration, protecting expensive handpiece bearings from premature failure and reducing hand fatigue for the clinician.
4. Fine-Grain Tungsten Carbide Composition: Manufactured from premium K30-grade fine-grain tungsten carbide. This high-density material ensures maximum edge retention and fracture toughness, even during high-torque tasks like surgical tooth sectioning or old crown removal.
5. Advanced Blade Geometry & Thermal Control: Features cross-cut or plain-cut blade configurations with scientifically calculated flute depths. This design facilitates rapid debris evacuation and optimal cooling-water flow to the cutting site, preventing thermal damage to the dental pulp.
