K-FILES NITIFLEX (21mm & 28mm) 15-40 are precision endodontic instruments designed for efficient root canal preparation. These NiTi rotary files feature superior flexibility and resistance to cyclic fatigue, making them ideal for navigating curved and calcified canals. Available in two working lengths—21mm and 28mm—with sizes ranging from 15 to 40, they deliver consistent cutting performance and reduced chairside time. The nitinol construction ensures durability through multiple uses, while the tapered design promotes optimal debris removal. Essential for general practitioners and endodontists seeking reliable, cost-effective canal instrumentation.
