Micro-grain Carbide and PVD/CVD-coated Carbide


Excellence in precision machining and machining of hard-to-cut materials

These material grades use WC micro-grain carbide, the hard layer of which is granulated to a micro size 1µm as the substrate. Furthermore, the substrate is coated by the PVD method with TiN, TiCN, and/or TiAlN. The end result are materials that are suitable for precision machining and machining of difficult-to-cut materials. Inserts in these grades are tougher and harder than carbide and come with precision sharp cutting edges. They even have superior toughness and sharper cutting edges than ultra micro-grain carbide grades, with excellent wear resistance and thermal crack resistance.


The result of intensive reseach and development for improving carbide grades

The NTK carbide grade series show very stable performance under a wide range of conditions. NTK uses micro-grain carbide well balanced between wear resistance and toughness, as substrate.



FeaturesSuperior cutting performance

        Relentless pursuit of better cutting performance
NTK takes pride in its carbide grade series for their outstanding cutting performance as a result of grinding ultra sharp cutting edges. This outstanding cutting performance benefits in better burr control, lower tool pressuer, stabilized dimensions and improved work hardening control.

FeaturesPrecise analysis on insert wear patterns

        Continuous research on insert tool life
Damage to insert cutting edges vary depending on the machining process and the work material. There are various types of coatings that reduce such damages to prolong the tool life. NTK carbide series offer a variety of coated insert grades which have been developed to improve their resistance characteristics, including wear, fracture, adhesion, oxidation and the likes, by utilizing our state-of-the-art technologies.
