Sirius TNMG carbide inserts are made for general machining applications in steel. The benefit of using TNMG over a CNMG insert is reduced vibration due to the wider cutting edge contacting the material when used with a 90° tool holder. PTFNR tool holders should be used for facing and PTGNR tool holders should be used for turning.
