Key Features
HyFlex EDM
EDM + CM-Wire with regenerative memory — manufacturer reports enhanced fatigue resistance (bench data; figures vary by comparator and test setup)
iRaCe Plus
Extended 4-file sequence (R1a-R1b-R2-R3) designed for narrow and/or severely curved canals where standard iRaCe R1 (15/.06) cannot reach working length — uniform 600 RPM / 1.5 Ncm settings
