Coltene HyFlex 4% 21mm Rotary Files are advanced nickel-titanium endodontic instruments manufactured using proprietary Controlled Memory (CM) technology. Designed to provide exceptional flexibility and resistance to cyclic fatigue, these files adapt naturally to root canal anatomy while maintaining efficient cutting performance. Their conservative 4% taper helps preserve tooth structure while ensuring predictable and safe canal shaping, making them ideal for curved, narrow, and complex root canal systems.
Pack of 6 Rotary Files
HyFlex CM files are engineered to follow the natural curvature of root canals, reducing the risk of ledging, zipping, and transportation. Their unique memory alloy technology allows temporary deformation during use and restoration of shape after sterilization, enhancing safety and longevity. The conservative 4% taper is particularly beneficial in preserving dentin while achieving effective canal preparation.
