NT Rainbow S Rotary Files - 25mm (Pack of 4)

NT Rainbow S NiTi Rotary Files are high-performance rotary instruments engineered for efficient and safe root canal preparation. Made from premium nickel-titanium alloy, they undergo precise heat treatment and surface enhancement processes to deliver the ideal balance of flexibility and durability.

Their advanced heat treatment and surface therapy minimize crack formation and significantly increase resistance to cyclic fatigue. The slim S-shaped cross-section provides excellent flexibility, allowing smooth navigation in curved canals, efficient debris removal, and reduced preparation time.

These files feature an inactive tip design to ensure safe canal shaping and minimize the risk of perforations or zipping. The variable pitch design improves mechanical resistance and lowers the chance of tip fracture. Additionally, the files can retain a pre-curved shape at room temperature, making customization easy.

Available in multiple lengths and sizes, each file is clearly marked with its taper value on the handle. With a recommended speed of 400 RPM and torque of 2 Ncm, NT Rainbow S Files offer precision, safety, and efficiency for modern endodontic procedures.
