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)
Vortex Blue
Blue heat treatment provides min 65% better cyclic fatigue resistance vs M-Wire NiTi and at least 42% higher peak torque strength (manufacturer data)
