CNGA 12 Size ISO Indexable Inserts with 4 Edges
Double Edge non-regrindable CNGA PCBN (80° rhomboid) turning insert from Nikko Tools, designed for machining high hardened steels, cast iron and heat resistant alloys. CBN inserts can eliminate the need for additional grinding processes.
For best results with PCBN turning inserts, a high quality DOUBLE CLAMP turning tool holder or boring bar should be used to minimise vibration and maximise tool life. For hardened steel it is also recommended to machine dry.
