Abstract
Disclosed is a PVD ceramic thin film-coated cutting insert properly usable for machining a hard-to-cut material such as inconel or titanium having low thermal conductivity. The cutting insert for hard-to-cut materials includes a cemented carbide base material having an SMS value of 50-80% obtained by [Formula 1] below, and a ceramic thin film formed on the cemented carbide base material and having a thickness of about 0.4-1.5 μm. [Formula 1]: SMS=Saturation magnetization value of sintered body×100/TMS, where TMS=2010×Mass ratio of Co.
