Material Advantages
- High‑quality imported nickel‑titanium wire – high purity, with superelasticity and shape memory effect.
- Heat‑activated treatment – imparts a golden finish, boosting flexibility and fatigue resistance while retaining hardness.
- Modular heat treatment – segmented temperature control for region‑specific processing, balancing flexibility, cutting efficiency and fracture resistance.
Design Features
Cross‑section: Convex triangular groove cross‑section – provides strong cutting efficiency and smooth chip removal.
Tip: Safe, blunt non‑cutting tip – effectively reduces the risk of root canal lateral perforation.
Taper: Gradually increasing taper design (SX–F3) – adapts to various root canal shaping requirements.
Length options: 21mm / 25mm / 31mm available.
- Clinical Parameters:
Recommended rotational speed: 260–360 rpm
Torque: 2.0–2.5 Ncm
Model Function Division
- SX (Pioneer File)：19mm short length with no color ring. It is specially used for short posterior root canals to establish coronal patency and quickly open the canal orifice.
- S1 (Purple ring)：Performs preliminary shaping on the coronal and middle segments of root canals, forming a standard “wide coronally, narrow apically” canal morphology.
- S2 (White ring)：Finely trims the middle canal segment, optimizing the passage for apical finishing files and avoiding ledges or canal transportation.
- F1 (Yellow ring)：Specially designed for apical preparation and final finishing of fine and narrow root canals.
- F2 (Red ring)：The final finishing file for standard root canals, creating an ideal canal shape for root canal obturation.
- F3 (Blue ring)：Suitable for large root canals and canals with apical resorption. It completes large-diameter apical finishing for special and complex clinical cases.
Core Features
- Excellent flexibility and high cutting efficiency – balances shaping speed and safety.
- Strong fatigue resistance and fracture resistance – minimizes instrument wear and tear.
- Triangular groove design for effective chip removal – reduces debris accumulation within the root canal.
- Efficient and time‑saving operation – suitable for rapid root canal preparation.
- Golden large‑taper design – focuses on efficient, high‑speed cutting, ideal for routine simple root canals, pursuing ultra‑fast preparation with low instrument loss.
