Clinical Tip

Same manufacturer, two motions. 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.
