K3XF is a ground R-Phase rotary system for any torque-controlled motor at 350 RPM / 3.0 Ncm with 24 size/taper options; TF Adaptive is twisted R-Phase NiTi that switches between rotation and reciprocation according to canal load and runs only on a Kerr Elements-class motor in the TF Adaptive program. Choose TF Adaptive for severe curvature with the dedicated motor, K3XF for taper choice on standard equipment. [K3XF →](https://endo-guide.app/system/k3xf)[TF Adaptive →](https://endo-guide.app/system/tf-adaptive) K3XF vs ZenFlex Both are pre-bendable Kerr rotary files — ZenFlex in controlled-memory wire, K3XF in R-Phase heat-treated NiTi. ZenFlex is single-use, 500 RPM, .04/.06 in sizes 20–40 with a 1 mm flute diameter for conservative shaping; K3XF is reusable within limits at 350 RPM / 3.0 Ncm with 24 configurations up to .12 orifice openers. Choose ZenFlex for minimally invasive single-use shaping, K3XF when you need larger tapers and reuse.
