The wider space of the cutting edge stores more dentin debris, allowing the debris to be discharged from the spiral and avoiding apical blockage.
Unique 3S cross section
- A rounded safety guide tip without a blade
- Three sharp cutting edges
- Guiding tip without cutting force
- Large and deep chip space
- Avoid LEDGE FORMATION, offset, lateral penetration, or root tip
- Minimal root canal wall contact

Selection of the most advanced third-generation Nitinol material, with more excellent fatigue resistance and flexibility.
