Key Features
HyFlex CM
Pre-bendable like stainless steel with enhanced cyclic fatigue resistance vs conventional NiTi (manufacturer reports up to 300%, in-house bench data)
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
