Design Features

• Multi‑flute compact spiral structure
• Compact and uniform helix pitch
• Small angle between cutting edge and axial axis
• Tight flute pitch for large contact surface area
• Uniform shaping and stable canal tracking
• Ideal for root canal patency and refined preparation
• Superior torsional resistance
• Primarily for rotary cutting
  

Core Functions

• Basic rotary nickel‑titanium K‑file for root canal treatment, compatible with endodontic motors. It integrates root canal patency, shaping and refined preparation, making it one of the most widely used rotary files in clinical practice.
• Material Advantages: Constructed from medical‑grade nickel‑titanium alloy, it delivers excellent elasticity and fatigue resistance, adapts to complex root canals and minimizes the risk of file fracture.
• Versatile Cutting: Bidirectional spiral cutting edges support both rotary and push‑pull motions. It achieves uniform cutting and superior shaping performance for patency, shaping and refined preparation.
• Complete Specifications: Offered in 21mm and 25mm lengths, it covers full ISO standard sizes #08‑#40 with clear color coding for quick identification.
• Clinically Friendly: Its smooth surface and stable cutting performance reduce ledge formation and canal transportation. Compatible with various endodontic motors, it enables efficient clinical operation.

Clinical Use 

• Preoperative check: Inspect files for deformation or cracks; confirm motor speed and torque to prevent file fracture.
• Canal patency: Use small‑size files to establish a smooth glide path. Do not force advancement.
• Preparation: Mount the file onto the motor; apply rotary and push‑pull motions. Prepare sequentially from small to large sizes with gradual depth penetration.
• Irrigation: Irrigate with sodium hypochlorite or other irrigants after every 1–2 files to remove debris.
• Refined preparation: Use target‑size files to refine canal walls and avoid ledge formation and canal transportation.
• Postoperative check: Verify canal patency and taper; clean and store instruments properly. Record service cycles and discard once the usage limit is reached.
