Multidirectional and High Feed Back Turning with No Down Time and High Productivity

The XNMV 1105 is a double-sided 4-corner insert with a 70-degree angle. It combines the advantages of the ISO CNMG and DNMG inserts for various machining applications such as external turning, face turning and external profiling. Highly efficient machining with a maximum 3.5 mm depth of cut in both external forward turning and face turning as well as good chip control. An additional advantage of the XNMV 1105 insert is its unique high feed backward turning capability. This technologically advanced capability is made possible due to the insert’s helical cutting edge that works to reduce cutting forces as well as the insert’s lower entering angle – both features greatly contribute towards higher productivity. In addition, the insert’s rigidity is strengthened by its increased thickness while its stability is improved by the insert’s wide support surface.
