Key Features
TF4
Four-file hybrid sequence (T20 20/.07, T25 25/.07, T35 35/.06, T45 45/.05) where T25 25/.07 is run in reciprocating motion within an otherwise rotary workflow at 350 rpm / 2.0–3.0 N·cm (per IFU spec table and step-by-step)
TF Adaptive
Adaptive motion automatically transitions between rotation and reciprocation based on canal stress
