Clinical Tip
HyFlex EDM is electro-discharge-machined CM-Wire that regenerates its shape in the autoclave and is reusable within limits, with a OneFile 25/~ plus orifice opener, glide path and finishing sizes at 400 RPM / 2.5 Ncm; RACE EVO is a blue heat-treated three-file sequence at 800–1000 RPM / 1.5 Ncm, usable for up to 8 canals per its IFU. Choose HyFlex EDM for extreme curvature and autoclave shape recovery, RACE EVO for a fast uniform-setting sequence.
