These tools covered in multi-layers by advanced vapor deposition technique are well-received by the experts and users at home and abroad for its highest quality and long serviceable life.

Especially, the hard alloy insert for processing cast iron and steel was highly appreciated at an exhibition sponsored by the World Intellectual Property Organization in Geneva. It is very ideal for precision processing and stainless steel processing.

Such tools as constructional bite and line drawing die which are cemented with titanium nitride by chemical vapor deposition provide sufficient qualitative guarantee to cope with rapid, intensive and precision cuttings.

The constructional hard alloy tools and various kinds of cutting inserts intended for machine tools and mining tools which are of proper mechanical intensity and strictly standardized are widely used at the coal and ore mines and machine-building plants across the country.
