Orifice opener (17/.08) operates at 300 RPM / 3.0 Ncm; all other files at 350 RPM / 2.5 Ncm (per Eighteeth series brochure). Note: a distributor spec (Alkaramdent) lists a flat 350 RPM / 2.0 Ncm — series brochure from eighteeth.com is used here as the manufacturer source.
Gold heat-treated Control Memory NiTi wire provides enhanced flexibility and cyclic fatigue resistance (per brochure).
The system includes an integrated orifice opener (17/.08, 19mm) and glider (19/.02) — no separate glide path system needed.
Available in three sub-variants: Standard (variable taper .04 with orifice opener + glider), .06 Taper (sizes 15-35), and Wide Canal (.04 taper, sizes 20-50) (per specs).
Non-cutting safety tip reduces ledge formation and apical extrusion; variable pitch reduces screw-in tendency (per series brochure).
