NT Rainbow S NiTi Rotary Files are advanced rotary tools designed for efficient root canal preparation. Crafted from high-quality nickel-titanium alloy, these files undergo precise heat treatment and surface enhancement processes, combining flexibility with durability. One key feature is their innovative heat treatment and surface therapy, which minimizes crack propagation, enhancing resistance to cyclic fatigue. Their slim S-shaped cross-section offers exceptional flexibility, facilitating navigation through curved root canals while efficiently transporting debris and reducing preparation time. The files boast an inactive tip design that ensures safe preparation, reducing the risk of perforations and zipping. Their variable pitch design enhances mechanical resistance, reducing the risk of tip fracture. Moreover, their unique property of retaining a pre-curved shape at room temperature allows for easy customization. Available in various lengths and sizes, each file is conveniently marked with its taper value on the handle. With a recommended speed of 400 RPM and a torque of 2 NCm, NT Rainbow S files are the choice for precise, safe, and efficient root canal procedures.
