Document Type and Number:
Japanese Patent JP2004516948
Kind Code:
A
Abstract:
The present invention relates to cutting tool insert consisting of a tungsten carbide based hard metal substrate and a coating. The hard metal consists of about 4-15 wt-% binder phase with face centered cubic structure and a composition of 35-65 wt-% Fe and 35-65 wt-% Ni in addition to dissolved elements. As a result, inserts have been produced with at least as good performance in machining as conventional state-of-the-art inserts with Co-based binder phase. The insert can be applied in milling and turning of low and medium alloyed steels as well as stainless steels.
