Cermet NAX Series for Milling

Cermet

The NAX series is developed as a series of Cermet material for cutting tools by Nachi's original sintering technology and traditional tool making expertise.

We propose the best Cermet grade for each application and provide the most suitable shape of blanks with small lots and short lead time.

Features

Cermets guarantees high quality machined surface due to their low chemical affinity to steel.
Various grades for Turning, Milling, and Tipped Saw Blade applications.
Not only tip blanks but also special shape tips are available upon request.

 Cermet grade name, For Tipped Saw Blade
