The GTN insert is a popular parting insert and is the standard insert used within our Parting-off range. This particular GTN-4 is a 4mm wide self gripping parting off insert and its general purpose grade is designed to cut most materials including stainless steel, mild steel, brass, bronze aluminium and cast iron.  The 4mm thickness is excellent for those large lathes requiring additional strength for those large parting cuts.
