60 Degree Triangular Turning Inserts
Adaptable Mitsubishi Type
60 degree triangular turning inserts, the insert shape is triangular, the ISO code starts with "T", it is a positive angle single use insert and has a total of 3 cutting edges. This insert is mainly used for semi-finishing and finishing of internal holes. It is occasionally used for external diameter machining, but this is not common. Because our inserts are designed with unique chip evacuation grooves, they can achieve a greater depth of cut in internal hole machining, and the chip evacuation effect exceeds other products on the market.
As a global expert in manufacturing tungsten steel inserts, we offer high quality 60 degree triangular turning inserts to meet your precision machining needs and ensure the best machining quality and efficiency.
