Kerr K3XF Nickel Titanium Rotary Files, #40, .08 Taper, 21mm, Black, 6/Pk, 823-8401
K3XF NiTi rotary files are third-generation, triple-fluted asymmetric endodontic instruments featuring proprietary R-Phase Technology for exceptional flexibility and resistance to cyclic fatigue. They are roughly half the stiffness of other files and twice as resistant to fracture, with a third radial land for better centering and stability, variable pitch for improved control and coronal debris channeling, and a stainless steel Axxess handle for better posterior access. This pack contains six size #40, .08 taper, 21mm files (black, item 823-8401).
